Making the Most of Digital Camera Memory Cards

Thursday, December 25th, 2008

John Pawlett asked:

Digital cameras are revolutionizing the world of home and professional photography, but they are married to memory cards just as traditional cameras are married to film. Making the best use of memory cards can have a very big impact on your enjoyment of digital photography. Choosing the right memory card for the job can be as important as choosing the right film for a traditional camera.

If you are new to digital cameras, the digital camera memory cards are the most important parts of any digital camera, without which they may not work at all. So if you are handling a digital camera or planning a purchase, you must know more about the memory cards used in these cameras.

Something many new digital camera owners find counter-intuitive is that bigger is not always better with a digital memory card. The actual response speed of your digital camera can depend greatly on the memory card it is using. The speed that your camera writes new pictures to the digital memory card is partially dependant on the transfer speed of the digital camera but is also dependant on factors in the memory card itself.

Memory cards that have buffers can take the data into a faster type of memory and then transfer the data from there to the slower flash memory which provides the main storage of almost all digital camera memory cards. Some digital camera provide their own buffer memory to allow you to take your next picture while the previous picture is being transferred to the memory card.

When you delete an image from the memory card of your digital camera, the flash memory is reconfigured because of special issues having to do with how this memory stores data. Normally this is an issue that you don’t have to worry about at all. However, if you have a very large memory card and delete an image, you may experience a several minute delay while house cleaning is performed on the memory card. Because of this, do not delete images while you are taking pictures.

Instead wait until you are at home, your hotel or in the car before reviewing your pictures and deleting the ones you don’t want. Smaller cards take less time for this house cleaning so many experienced digital camera owners will choose to have more than one medium sized memory card instead of one very large one.

Now the question arises-how many memory cards are enough for your camera? On an average basis, you must have at least two memory cards for your digital camera. That is, if you are using it in a normal and average fashion.

Most professional photographers choose to carry about four to six memory cards. This helps them shoot smoothly and constantly. If they run out of memory, they just take the loaded card out and insert the fresh one. Because memory cards can malfunction (just like traditional film canisters, but not as often), you should choose to have at least two memory cards at all times.

By having at least two cards, you can work with one and keep the other in reserve for emergency. Having at least one extra memory card for your digital camera will also ensure that you have the backup protection needed if you run out of space on your first card or in the possible event of the first card malfunctioning.

The next important issue is how to take proper care of these memory cards. The memory cards may seem like some small and fragile piece of technology, but they are actually fairly sturdy. The flash memory is encased in a stiff plastic shell which can withstand normal wear and handling. At one end of the memory card is either a set of little holes or copper strips. These are the sensitive part of the card. Any voltage source or a large jolt of static could corrupt the memory and probably cause permanent damage to the card. When the card is not in your camera, it is best to keep it stored in a protective case or in your camera case. Putting it in your pocket could cause a short (from your keys perhaps) or dirty the electrical contracts.

There have been instances where the users have misbehaved greatly with them and the memory cards have yet survived and continued to function correctly. But, this does not mean that one should not care for them.

When it is time to transfer your data from the memory card to your PC, it is best to have a memory card reader, or have a PC with a built-in reader. The data cables provided with most digital cameras are very slow compared to the speed of a direct reader and it is often easier to review, copy and delete images from a memory card when using a reader instead of through the data cable connection.

When traveling, X-Rays have never been shown to corrupt the data on, or damage, a digital camera memory card. The memory card is also not magnetic in nature so the motors in the X-Ray machine’s conveyor belt should not be able to cause any harm either.

Armed with knowledge comes the power to benefit from that knowledge. If you have learned something new about digital memory cards, hopefully you will benefit by enjoying your digital camera more and finding more opportunities to take great pictures.

Making Your Digital Camera Batteries Last Longer

Roberto Sedycias asked:

Digital cameras, also known as filmless cameras are one of the most intelligent inventions of late. Because before digital cameras, even the most high end cameras were chemical process dependent for photo printout.

But in digital camera, images are recorded electronically by an inbuilt computer. Though initially they were beyond the reach of normal people due to price factor, now they are available in within an affordable range.

Battery is an important component of any digital camera. In fact the longevity of your digital camera depends upon the performance of its battery. First thing to remember is never go in for alkaline AA batteries as they have shorter life span. Always opt for rechargeable batteries called as NiMH. Although they are a bit costly as compared to alkaline AA digital camera batteries, but they can be reused for a long time.

If you are going out on a long trip, it is a good idea to take extra rechargeable batteries. You never know when they will come handy as digital cameras consume power from batteries quickly even if you use rechargeable ones.

While going on a trip, it is also advisable to take battery charger along with you as digital camera batteries may lose their charge over time. Having a charger is helpful especially if u r novice in digital camera photography for you tend to consume more batteries while clicking the perfect shot. Here are some other helpful tips to increase the longevity of your digital camera batteries.

It is always advisable to remove the batteries when the digital camera is not in use. This simple precaution can ensure the longevity of batteries.

Never let your digital camera batteries get wet as water can corrode the batteries and eventually damage them.

You should have prior knowledge about this fact that, if you are using MicroDrive media these miniature hard drives may take up quite more power than Compact Flash cards and hence extra rechargeable batteries are a must.

Turn off your digital camera when not in use. If you are in a situation where you must snap pictures quickly, this may not be a wise suggestion, but if you are in no hurry and can afford a couple of seconds before snapping a still subject, by all means, conserve your digital camera`s energy.

You do not need to stop and take a look after taking photo every time as by doing this does use up your digital camera`s battery power. However, once in a while, it is good to check if your exposure, lightening is perfect or not.

Now-a-days, many digital cameras come with regular viewfinder and an LCD viewfinder facility. While the digital LCD viewfinder has better resolution, it can drain battery power. Turn it off when applicable and use your regular viewfinder for taking pictures.

Try to keep your image playback to a minimum as they can drain out the battery power.

While replacing batteries in a digital camera, it is recommended that their mAh values match. The `mAh` stands for Milliamp Hour is a technical term used while describing how much power a particular battery will hold. It might be possible that one lesser mAh battery will drain before the others, resulting extra strain on the remaining batteries.

For better performance, do check in for an add-on power pack that uses AA NiMH batteries in your digital cameras.

When your AA NiMH batteries stopped accepting a charge, do not throw away them for they are recyclable. Contact your battery manufacturer or local recycling agency to see if these dead batteries can be recycled.

Always make sure to insert similar batteries into your digital camera battery charger. Miss-match set of batteries can result in damaging the batteries or the charger, and in extreme case, a fire too can ensue.

Taking proper care of your digital camera batteries ensures optimum and long lasting performance. Hope the above tips will come handy for the consumers of digital cameras.

Digital Camera Handling And Maintenance

Tuesday, December 16th, 2008

Roberto Sedycias asked:

A photographic camera is an apparatus for taking photographs or moving film. All cameras have the same basic design – a lightproof container with a lens and a light-sensitive surface. A digital camera is different from a standard 35 mm SLR (single lens reflex) in the sense that digital cameras require no film rolls.

In earlier times careful planning went into taking pictures of an object but with a digital camera you can take a number of photographs and then select the best posture that you have captured while the rest of the pictures can always be deleted without involving any monetary loss. The pictures can then be transferred to your personal computer from where you can take out printouts if you have a color printer installed.

The quality of the photographs in a digital camera depends upon the camera resolution which is determined by pixels. Pixels or picture elements are any of the minute areas of uniform illumination of which an image on a digital display screen is composed. The greater the number of these pixels, the sharper is the image created. A digital camera which offers a resolution of 5 mega pixels is normally considered a good camera.

The weight of the digital camera also goes a long way in camera selection. Once upon a time digital cameras used to weigh one kilogram but with technological advancement they have become very compact and sleek. These modern cameras now come with zoom facilities. You can use digital zoom in any picture-taking mode to get up to 3X magnification beyond optical zoom.

You can do more with your digital camera like using different modes. General picture taking offers an excellent balance of image quality and ease of use. Point-and-shoot simplicity function is provided when taking pictures under special conditions. You can capture video with sound. You can view your favorite pictures. To capture far away scenes, the camera uses infinity auto focus. The camera automatically sets the focus distance depending on the zoom position.

Most digital cameras permit a white-balance setting which automatically transmits by inference which element should look white and which should look black. The lens is an integral part of any camera and determines the quality of the photographs. All digital cameras have LCD screens which can vary in size.

Care and maintenance of your digital camera is of utmost importance. If you suspect water has gotten inside the camera, remove the battery and memory card and allow all components to air-dry for at least 24 hours before using the camera. Blow lightly on the lens or LCD to get rid of dirt and dust. You should always wipe softly with a lint-free and soft cloth or lens cleaning tissue. Never use solutions unless intended particularly for camera lenses. Never allow chemicals such as sun tan lotion, to contact painted surfaces.

For digital camera, battery care is vital. Do not allow batteries to touch metal objects, including coins. Otherwise a battery may short circuit, discharge energy, become hot or leak. Always remove the battery when the product is stored for an extended period of time.

If your budget allows always buy a digital camera that provides you with higher resolutions, longer zoom lens and some other special features. Advanced consumer cameras usually require that you spend some time with the instruction manual to master all their capabilities, but they have few limitations.

Digital camera assures a user friendly working with pictures and videos. If accidentally you delete a picture you can use the undo delete function to retrieve it but this should be done immediately after you delete a single picture.

Look Through a Digital Camera Review Before You Buy That Camera!

Friday, December 12th, 2008

Brooke Hayles asked:

When deciding on a digital camera, looking through a digital camera review first can help tell you about each camera. Each camera has different options and a digital camera review will help you decide which fits your needs best. As we all know, the digital camera is much different than previous camera models. Before the digital boom began, cameras operated purely on mechanical and chemical processes.

If you’re new to the world of digicams, then you will need to remember that unlike their predecessors, they work through a built-in computer. This allows pictures to be captured electronically. With the popularity of these amazing gadgets, prices have dropped and what was once far too expensive for the average person, has now become just as affordable as film cameras.

Different Digital Camera Styles

Digicams, a common phrase for digital cameras, come in many shapes, sizes and features. As you look a digital camera review keep in mind if you are interested in a small, pocket sized camera or a larger model that has more features than the pocket sized. Point and shoot digicams are the most popular, but the larger camera with its additional features can be a good investment for your money.

Due to its convenience, the pocket sized cameras are wanted most often. A digital camera review will reveal that the small camera can be quite expensive due to the necessary technology needed to operate such a tiny camera. As you get further into your digital camera review you will see the phrase digital SLR. The SLR style is for the serious photographer. The professional SLR style of camera will produce the highest quality of photograph.

The SLR has quite a few enhanced features. One of its features includes the ability to switch lenses on the need of the situation. Of course, the SLR is also the most expensive of digicams. As you read through a digital camera review it will become obvious that most people’s photography needs are met with either a standard or pocket sized digital camera. However, if photography is a hobby of yours the SLR models may interest you greatly.

Digital Camera Tips

One term that you will find often in a digital camera review is “pixel.” Pixels refer to the individual dots that make up the picture. You may be more aware of the term “megapixels.” This term is the same as pixels, but measured by the thousand.

You may notice in the digital camera review that the more megapixels a camera has, the more expensive it seems to be. The reason behind this is that the more pixels a camera has, the high-quality picture your camera will take. Most digicams have either 3-4 megapixels. Earlier models have less, but it’s easy to find a reasonable priced camera with either 3 or 4 megapixels. If you plan to use your camera for family photos and to print 4X6 photos, this will suit you just fine. If you want to print pictures at the size of 8×10 or more, a digicam with more megapixels will keep your pictures sharp.

If you own a PC and then purchase a digital camera, you can upload your pictures to your computer. With special paper you can then print your own photos at home!

Summary:

A digital camera review will help you decide which camera will suit your needs best. Do keep in mind that digicams operate differently than film cameras. Since digital cameras record images electronically you can upload them to your computer and share them easily via email!

History And Type Of Digital Cameras

Friday, December 5th, 2008

Roberto Sedycias asked:

A digital camera is such a camera that will take either video or still snaps digitally. It records the images digitally on a light-sensitive sensor. Some digital cameras can take still snaps as well as video and audio. The digital cameras have become very popular nowadays and more and more people are opting for rather than regular cameras.

Digital cameras are technologically much advanced and have many user-friendly features that are usually not found in regular cameras. One such very good feature is that it displays the image on the camera’s screen just after you catch it. Thus you can click and record millions and millions of pictures, keep the ones you want and discard the others. After the pictures or videos are recorded, you can edit the images and thus can be a virtual master of the background, people etc. Imagine the fun when you can change the background of a picture taken at your home to be changed to a Hawaiian beach, or changing the hair color of your sister to a wild pink and many other things. The choices are unlimited.

Nowadays digital cameras can be incorporated in many devices like PDAs or mobile phones or computers etc. Some astronomical devices like Hubble Space Telescope also use specialized digital cameras.

Digital camera technology has evolved from the similar technology that first recorded television images. It was in 1951 when the first video tape recorder was used to capture live images using television cameras. They converted the information in electrical impulses and saved the information on magnetic tape. It was actually due to NASA`s space technology that used digital images to capture photographs of surface of moon and advanced computer technology that led to major developments in digital photography.

Government was also using this technology in forms of spy camera and the time that being spy satellites and it contributed immensely in advancement of science of digital imaging. Soon private companies like Kodak, Sony etc were releasing professional digital cameras for ordinary people. Their strong marketing tactics worked and today digital cameras are found everywhere.

There are many varieties of digital camera and we will discuss some of them. Compact digital cameras are one of such varieties and are designed to be small as well as portable. The miniature versions are called subcompact cameras. Though they do not have much advanced features or excellent image quality but they are very simple to use and easy to carry around. Images are stored using Lossy compression in JPEG format. Such cameras are generally equipped with a low power, built-in flash usually sufficient for close subjects. Live preview is generally used for framing the photos. They are perfect for casual and home use.

Another type are Bridge cameras that are higher-end cameras. They resemble DSLRs and also share some advanced features with them but just like compact cameras, the photo framing is done with help of live preview and they also have small sized sensors. A Fuji film FinePix Bridge camera is also equipped with super zoom lenses that give you a chance to take very distant shots, though at the cost of image quality.

Another type is Digital single lens reflex cameras that are based on film SLRs or single-lens reflex cameras. These cameras are characterized by the presence of a mirror-reflex system. Other types include rangefinder and are generally used for film cameras, professional modular digital cameras that are assembled from different modular components and used for specific purposes. The common brands for such cameras include Mamiya and Hasselblad.

Digital Camera Basics – Want To Stop Being An Idiot And Learn How Digital Cameras Work?

Tuesday, November 25th, 2008

Mike Singh asked:

With the advancement of the digital camera and the software that is made for them, most pictures look professional from the first click of the camera. But like most things, it is important to understand the “how and why” for higher quality results.

The basics of a digital camera revolve around terms like pixel, pixel count, white balance, sensor, sensitivity, optical zoom, or digital zoom. These improve your understanding of what digital photography is all about, and will help you become a more efficient photographer.

For example, one important term is digital sensor. A typical digital camera may have a digital sensor element that is as big as a small finger nail. Most 5MP digital cameras use a sensor that is 7mm x 5mm in size. This is much smaller than the size of the negative of a 35 mm camera. However, high-end digital cameras have large sensors, and generate superior images. These are important things to know, to see how pictures can be better or worse.

Digital cameras also have sensitivity settings similar to ISO ratings on film. Most digital cameras will have settings for sensitivity equivalent to ISO 100 and ISO 200. Many also have a setting for ISO 400. A few expensive digital SLR cameras with large sensors have settings for ISO 3200 or even for ISO 6400.

Most digital cameras have an optical and a digital zoom. An optical zoom lens works by changing the focal length and magnification while the zoom is being utilized – with the image quality remaining high. Digital zoom works by cropping the image to a smaller size. The cropped image is enlarged to fill the frame, causing a significant loss of quality.

The manufacturers of digital cameras use the term “pixel count” to describe their camera’s image properties. The word pixel originates from “(PIC)ture (EL)ement”- with the use of phonics added for emphasis. It represents a single point in a graphic image – not a dot but an abstract sample that can be reproduced in any size, without a dot or square appearance.

A pixel is important to understand because it is the basic unit of measurement, used to define a digital photograph. The more the number of pixels per square inch, the higher the resolution of a digital picture, increasing its clarity. Some examples would be 2,400 pixels per inch, 640 pixels per line, or spaced 10 pixels apart. Designers, artists, and photographers sometimes interchange the pixel terminology, such as dots per inch (dpi) with pixels per inch (ppi). The dpi is used when it refers to the printer’s resolution for the printing density. Each pixel is made up of three color channels – red, green and blue-and has a numerical value of between 0 and 255.

The pixel count also decides the size of a print in case you want to print photographs. A 3MP camera can provide excellent 4×6 inch prints, while a 4 or 5MP digital camera can deliver high quality 8×10 inch prints. With a digital camera you can pick the white balance to suit the light source. This is meant to ensure that white looks white, and not yellow or blue. Normally, your digital camera will do this automatically. You can also set the white balance yourself for better effects.

Since each pixel generates three bytes of data, a photographer using a 3MP camera will need a storage space of 9 million bytes or 9MB to store a single image. This is a huge amount of space. Camera companies therefore allow for a compression of image using a format called JPEG. This reduces the file size significantly but while doing so a lot of data is lost. To overcome this problem companies have come up with different storage formats. Canon calls it RAW while Nikon calls it NEF. The data loss is less in these formats.

The low end cameras used by beginners can shoot images whose pixel count is one million is categorized as 1 MP or one million pixel camera because the intensity of each pixel is variable, with each pixel having three or four dimensions of variability – such as red, green and blue, cyan, magenta, yellow, and black. The high-end cameras used by professionals, can range from 14MP to 22MP with a pixel count as high as 14 million or 22 million per image.

The thing to remember is the higher the resolution, the more realistic the image is, matching closest what the actual image is. So take your time, do some research, and talk to people who know cameras. Otherwise, a lot of money will be spent on something that is barely adequate for what you want.

Digital Cameras: Great Pictures Come With Superb Cameras

Digital Camera Buying Guide

Saturday, November 22nd, 2008
digital cameras
Monty Alexander asked:

Planning to buy a digital camera? Not sure how to get started?

Read on to discover how…..

What do you need the camera for?

If you buy a simple one that can be used at home, you will not get interesting capabilities that you need for taking really good photographic pictures. On the other hand, it would be a waste of your money if you have the latest digital camera only to be used for personal photos at home.

Based on the purpose one can choose from the following main three types.

· Point and shoot: – reasonably compact, with features and size like 35mm cameras.

· Lifestyle: – with moderate features, it’s sleek and compact, so you can carry it around with ease.

· Professional: – with interchangeable lenses, flashes and other accessories, this camera is robust and feature laden, just the right choice for a professional or serious photographer.

These are the important features to look for?

Pixel resolution

Digital images are made up of dots called pixels. The higher the number of pixels in your image, the better will be the quality of the image. This will therefore enable you to enlarge your image to higher pixel dimensions without creating a pixilated (broken) image.

Compression

Compression shrinks a photo’s file size, thus accommodating more images in the memory card. However compression causes a small amount of data loss. If you need the absolute best-quality images, you have to consider buying a camera that takes uncompressed photos but will accommodate less number of images.

Memory

A camera’s memory size will decide the number of images that can be stored. Memory of 128MB will be good enough if you want to use the camera mostly at a social do or a party. If you are on a vacation or when you cannot download images for days at a stretch, a memory of 512MB to 1GB will be most favorable.

LCD screen

Most digital cameras come with at least an optical viewfinder but many digital cameras also come with an LCD screen built into the back. For a digital camera, they vary from 1.5-2.5 inches.

Lens

It is the length of a camera’s lens that determines how much of a scene will fit in a picture. A “Normal” lens is about 50mm, most closely approximate to what your eye sees.

Optical zoom

This enables the photographer to zoom in on an object without any problem in picture quality. Depending on the magnification number, you can zoom in more.

Digital zoom

This feature enables the photographer to zoom in on the centre of the picture by removing the edges of the image.

Focus an exposure

In most cameras, the correct exposure for the lighting conditions is automatically determined. A camera rated ISO 100, has approximately the same light sensitivity as that of a traditional film camera loaded with ISO 100 film. A higher ISO rating means that the camera is more sensitive to light and is potential enough to take pictures in darker settings.

Audio and Movie capture

This feature allows you to record sounds and moving images at the same time, in exactly the same way that a camcorder functions. Some digital cameras provide the facility to record a few seconds of audio with each shot, thus letting you add a personal sound bite to your photos.

Movie mode

This is a feature that lets you take short film clips with your camera. The total record length is typically limited to 10 to 90 seconds.

Flash

Most digital cameras come with an in-built flash. Some cameras however include additional features, such as red-eye reduction or night portrait mode.

Image erase

Most cameras also let you select pictures to erase. This handy feature gives you the chance to edit out the photos you don’t want in order to create space in the memory.

Self-timer

A self-timer allows your digital camera for a delayed exposure, usually giving you about 10 seconds before the picture is taken.

Computer connections

Most high-end cameras have software and connections for both Mac and PC computers. However it is necessary to make sure the digital camera you want is compatible with your platform before you buy it.

Image stabilization

This feature enables the photographer to capture still images of something moving very fast.

Printing

Nowadays you can buy special printers, depending on the compatibility of your camera, to print off your pictures without connecting it to a PC. This applies both for digital and SLR Professional cameras.

How important is size and portability to you?

Size is another very important factor to consider. If you are to use the camera for non professional purposes the size has to be small as you cannot afford to carry huge sized cameras when you are enjoying a trip.

What is your budget?

Based on the budget the features will vary and the overall offering of a camera. Today’s digital cameras run anywhere from Rs 800 to Rs 30,000, depending on resolution and features. While the initial expense of a digital camera is still high you may find that the added convenience and savings in film and processing costs are worth it.

Slr Digital Camera: Advantages and Disadvantages

Thursday, November 20th, 2008

Russ Snapper asked:

A tough decision war happens to all who want to buy a digital camera, whether to buy a compact digital camera or an SLR digital camera. SLR is Digital Single-lens reflex camera, which is a standard tool for professional photographers. It provides the advantage of large, bright and accurate optical finder with large controls and fast operations.

Among the digital cameras, the SLR camera is the best for you provided if you are a family oriented person having a serious appetite for photography. For capturing pictures during family vacations, birthdays and holidays, the SLR camera will be the best companion. Though the point shoot cameras have increased to higher mega pixels, the choice of serious photography hobbyists and photographers is SLR. The clear reason for the choice is that SLR has the capacity for producing artistic photographs.

The main advantage and biggest difference that exit in the SLR is that there are more manual operations than the point-and-shoot cameras have. To get a perfect shot, your camera should be always in ready mode. SLR cameras offer instant start up and also minimum shutter lag. The point-and -shoot cameras have shutter lag of 2 or 3 seconds, which means you can miss a shot. The SLR camera’s shutter lag is less than a second and so you can get all the shots without miss. Another advantage is that the SLR cameras can accept interchangeable lenses. This helps you in getting best shots of sports and nature where you cannot go close for taking pictures. You can zoom the lens of SLR digital cameras and take close-ups. The other advantages are long battery life, high-speed continuous shooting, great image sensor and the ability to save RAW images.

The disadvantage is its larger size and you cannot fit it in your bag or purse. Not only larger in size, but also heavier and not suitable for vacations. It’s also very expensive when compared with compact and subcompact digital cameras. The SLR prices can range between $1,000 and $10,000. The best portrayal of SLR is its speed, clarity and optical system. It can be easily mistaken for a point-shoot camera but it is entirely different in the way it is used and the delivered picture quality. In real meaning, this camera enables you to look at the picture precisely without any alteration of digital features within the camera.

The digital SLR is built in such a manner that it enables to deliver high quality images. In a compact digital camera, the image that you see in the eyepiece or through LCD screen is generated digitally; but in SLR the image is sent by the lens and mirrors to viewfinder that reflects the images from one mirror to another. The digital SLR is versatile and that is why the image seen in an SLR is exact without any alteration. The interchangeable lenses allow you to utilize custom lens for a meticulous shot like Portrait, Landscape and Macro or Micro shots. Some lenses are even available for taking motion shots.

The image sensors in SLR provide good picture quality and quick shoot and click capability with no time lag. Detachable lenses give more attraction for photographers in choosing SLR as their choice. If you are not comfortable with manual operations SLR cameras have automatic settings and this provides transitional steps in learning to use an SLR.

Jonson William asked:

This electronic gadget should always be compatible with size, ease of use, manual options, battery types, shutter lag time. One thing to always keep in mind while purchasing a camera is that, it will solve your purpose in terms of personal or professional photography. The correct digital camera information will help you in taking decision for the right choice. Through those cameras, you will be able to share memory cards and batteries among your friends and family members. Camera’s brand lines are often similar and try to stay within the same brand. So, you can easily share your digital camera accessories with your family and friends. Now-a-days every one can own a digital camera and it is no longer a novelty now.
