Mohit Sharma asked:

The digital cameras have the ability to display the images on the screen immediately after the image is recorded. The images to be captured can be seen on its screen instead of its viewfinder. This way you can get a clearer preview of the image you are intending to capture.

The digital camera outdoes the traditional film camera in its image storing capacity too. The digital camera has the ability to store thousands of images on a single memory device. In addition you can even erase or unload the captured images onto your computer and reuse the camera’s inbuilt memory. In some cases you can even put a new memory card and store more pictures. Digital cameras also allow you to edit images. When capturing videos, digital cameras have the ability to record sound too, thus making video capturing a fun experience.

There are varied categories of digital cameras:

Video cameras: They are the cameras that exclusively record moving images.

The professional video cameras are the ones used for film production, etc. these have multiple image sensors thus enhancing the resolution of the end product. These do not have a inbuilt VCR or microphone.

The camcorder is another type of digital camera that has a microphone to record sound and an LCD screen to view the image that you are going to capture. This is mostly used by amateurs.

The web cameras are the type that is attached to the computers. Some of these web cameras have microphones, while some of them also include zoom abilities.

Compact digital cameras: They are small and portable; the smallest of them are called subcompacts. They are easy to use with not many special features or high picture quality. They have built in flash of not a very high power, but sufficient for close objects. It also permits live preview. They have a greater depth of field thus allowing objects from larger distances to come in sharp focus.

Bridge cameras: They are higher-end digital cameras that look a lot like Digital SLRs. Bridge cameras have the same advanced features as SLR and the live preview like the compact digital cameras.

Digital single lens reflex cameras: This is the digital camera that works like the single-lens reflex with a film.

Digital rangefinders: A rangefinder is an optical mechanism used to measure subject distance. They were once widely used on film cameras.

Professional modular digital camera systems: Mostly these cameras are used in studios for commercial production. Since they are bulky and difficult to carry they are rarely used in action or nature photography. They can be changed to digital or film cameras by simply replacing the back part of the entire device.

Line-scan camera systems: This type of camera is used in industrial areas in order to capture an image of a constant stream of moving material. This technology has the ability

These cameras are almost solely used in industrial settings to capture an image of a constant stream of moving material. Line-scan technology is capable of capturing data extremely fast, and at very high image resolutions.

Digital Camera – the Easy Way to Take Pictures

Roberto Sedycias asked:

In comparison to film cameras, digital cameras have number of advantages which includes displaying the image on the camera screen right after recording, a single small memory device can record thousands of images, records video with sound, provision to edit images, and above all storage capacity can be re-used by deleting the images. There are numbers of devices available that has in-built digital cameras like mobile phones, PDA`s etc. Specialized digital cameras are fit into astronomical devices like The Hubble Space Telescope.

Digitizing images on scanner and digitizing video signals are much older than making of still images using digital signals from an array of discrete sensor elements. It was then used for astronauts to provide onboard navigation information during their visit to planets. It provided the still photos of stars and planet locations during transit and also additional stadiametric information for orbiting or landing guidance while approaching planet.

Steven Sasson, an engineer at Eastman Kodak, attempted to develop first digital camera with solid state CCD image sensor chips. But it was just a technical exercise. The true digital camera was Fuji DS-1P developed in 1988. And the first commercialized camera was Dycam Model 1 in 1990. Then in 1991, Kodak launched its Kodak DCS 100. Else Casio QV-10 was the first consumer camera in 1995. Nikon D1, a 2.74 megapixel camera was the first digital SLR developed in 1999. And in 2003, Canon 300D, first 600 megapixel camera was launched.

There are various types of digital cameras available. For videos, there are professional video cameras which are used in television and movie production. Camcorders come with inbuilt microphone and a small liquid crystal display to watch video while recording and playback. One can get still photographs also with them. Webcams, attached to computers, can capture full-motion video and are also available with microphones or zooming ability.

In live-preview digital camera, there is an electronic camera that can be used to frame and preview before taking the photograph and also to review stored photographs. Many of such cameras can take motion pictures. Then the recorded images can be transferred to computer, printer or any other such device. USB mass storage device enables the camera to function as disk drive for computer and Picture Transfer Protocol is then used.

To use Firewire, storage device is removed from camera and inserted into other device. Compact digital cameras, small and portable with inbuilt flash, are easy to use, and images are stored using Lossy compression. They might be able to capture motion picture but that to a limit. Bridge or SLR like camera is higher-end-live-preview camera with more advanced features like superzoom lenses, takes movies with sound, etc. Digital rangefinder, a user operated mechanism, is capable to measure subject distance.

Apart from above mentioned digital cameras, there are other categories also. Professional modular digital camera systems are used in studios for commercial production. Line-scan camera systems, based on focusing mechanism, are used in industrial settings to capture images of constantly moving materials. They capture images at extremely fast with high image resolutions.

Most of the digital cameras come with pre-set modes for different applications. Data can be transferred through USB port, Firewire port, USB PTP mode and even through wireless connections like WiFi, Bluetooth etc. These data are mostly stored in Microdrives, Joint Photography Experts Group (JPEG), Tagged Image File Format (TIFF) and RAW. Formats for movies are AVI, DV, MPEG and MOV. Recently MP4 format is also developed. Digital cameras have small but powerful batteries to operate for enough length of time.

The Technology Behind Digital Cameras

Roberto Sedycias asked:

Technology has revolutionized the concept of capturing live images. The earlier concept of producing permanent photograph was based on pure chemistry. In 1830, Louis Daguerre, devised the first practical way of producing permanent photographs. Today we are talking about the computerized photo imagery in the filmless picture taken by a device that is smart in electronic intelligence and in appearance – digital camera.

A digital camera takes video, still photographs, or both digitally. It records images on a light sensitive sensor. Instead of using a film, an arrangement of charged-coupled devices-light sensitive semiconductors, which stores electrical charges,-does the job. These digital sensors-composed of pixels -transform the light from the scene snapped into an analog signal which is then converted into a digital version. One electronic filtering system regulates color and other picture components. Another system reduces the picture. The image is finally sent to a temporary storage area and ultimately onto a memory card. Many compact digital cameras can record sound, video and still photographs.

The images are transferred to a computer where they can be modified, printed, attached to email, inserted in web pages, etc. The most significant advantages of a digital camera are its memory capacity and ability to screen the images taken on a tiny video monitor.

The technology of the digital camera relates to the same technology of Video Tape Recorder. The first VTR in 1951 captured images from the television by converting the information into electrical impulses (digital) and subsequently saving them onto magnetic tape. It was in 1960s when NASA had made a major breakthrough by converting analog to digital signals by means of the space probe for mapping the surface of the moon. Also digital imaging had its other uses in spy satellites.

Kodak scientists invented the first mega pixel sensor capable of recording 1.4 million pixels. In 1991, Kodak released the first digital camera system- a Nikon F-3 camera equipped with 1.3 megapixels aimed at journalists. The first digital camera for the consumers which worked with a home PC via a serial cable were the Apple Quick Take 100 camera(1994), the Kodak DC40 camera(1995), the Casio QV-11 with LCD monitor(late 1995) and Sony`s Cyber-Shot Digital Still Camera(1996).

The main features of a digital camera can be summarized as follows:

Resolution: Resolution means sharpness of a picture. The higher the number of pixels, the higher is the resolution.

Memory: The pictures are stored like a data file in a digital camera. The size of the memory determines the number of picture which can be taken, stored and downloaded in the computer.

Flash Type: Most digital cameras have a built in flash of a range around 10 -16 feet which is required to provide extra light needed to take photographs in insufficient light.

Optical Zoom: Normally two types of zoom lenses are used viz., digital and optical. The optical zoom lenses serve more purpose like adding detail and sharpness.

Compression: This process helps to reduce the file size.

Lens: The length of a lens determines how much of a scene will fit into a picture.

LCD Screen: A very interesting feature of a digital camera is the LCD screen which permits one to see what the photo will look like before and after taking photographs, leaving room to decide whether to erase or save the photo.

In the market there are several brands of digital camera which are selling successfully and the continuous improvement in Technology is leading way to introduction of more and more exciting features in the digital camera.

Digital Camera – Indispensable for Life

Roberto Sedycias asked:

It`s really quite difficult to memorize the events that happen in our everyday life. Certain events of our life are forgotten which we don`t want to forget, but still we can`t help ourselves to remember them. But we can save them in the form of pictures so that we can memorize those precious moments when going through the pages of past events. It is possible when we have a digital camera to seize the moment.

In the early 2000, a digital camera with 1 mega pixel sensor costs nearly about $500 American dollars. But now, a digital camera with 5 mega pixel sensor costs less than $ 100 American dollars. This is possible due to the competitive market. Digital camera prices have dropped seriously and features have increased considerably than the previous days. Everyone possesses a digital camera for his personal use or for professional use. We are presently living in a photo crazy world. To take some brilliant shots we require a digital camera. Then, how can we live without a digital camera in such an environment!

Whenever you desire to purchase a digital camera, certain points should be kept in mind which helps you a lot and saves you from the future troubles you might face. Points you need to keep in mind are:

Thousands of digital cameras are available in the market, but you have to be cautious regarding the features and price you need to pay. Be sure that you get more benefits than the price paid for the camera.

Mega pixel used in the camera is also an important thing to consider while buying. The higher the mega pixel, the clearer the picture would be. The zoom facility of a camera helps you to take better photos. The more zoom facility will enable you to get better options.

Image quality of the digital camera is extremely important. Photographs should be eye-catching so that one gets easily impressed at the first sight.

Memory storage capacity of the camera is equally important as quality. If you take hundreds or thousands of photos continuously, then you have to go for the maximum memory storing digital camera.

Size of the camera as well as the size of grip, display screen (LCD) and buttons is also taken into account before buying a digital camera.

The optimum range for capturing photographs determines the quality of the photographs taken from a distant place. To take some brilliant shots we need to have a digital camera with maximum optimum range.

Photo quality should not change when they are taken in dim and dark conditions. This is another aspect of digital camera.

The digital camera should be compatible to your computer so that you can transfer the images or videos, edit them, add sound and send to your friends and relatives.

Professional photographers use digital camera with binoculars which is an essential gadget for them. With this they can watch birds, animals and objects in distant places easily and capture excellent photos as if they are near to them. The replay facility enables them to view the picture or video immediately after the shot.

The functioning of digital camera depends on its battery. Normally the batteries are rechargeable in nature. Still, life of the battery and the stand by time should not be ignored while buying the digital camera.

With such an extensive range of advantages Digital Cameras have already entered into our life. We are no more in a position to ignore its use in our daily life. Moreover, digital cameras make sweet memories sweeter for the rest of our life.

Roberto Sedycias asked:


A digital camera is an electronic gadget that can capture photographs and then store them. Instead of employing photographic films like the traditional cameras or using magnetic tapes to record images in an analog format like in video cameras, a digital camera stores photographs in an electronic way in a digital format. Nowadays we also get modern and multifunctional compact digital cameras that can record and store sound and video apart from pictures.

Digital cameras have become a rage everywhere in the world. They are amongst the top items of must-have lists of every home. Not only much more technically advanced with better features than their older versions, digital cameras are also very handy and practical. They come in a wide range and variety to suit everyone`s tastes and budget.

Apart from having a better picture quality, the most obvious advantage of digital cameras over the conventional ones is that you can click and store as many pictures as you want without worrying about wasting the film roll. After you have transferred the pictures to your computer, you can easily keep those you want, discard others, print some and may even edit the not so flattering ones. This clearly gives you a lot of options and choices as you can change the background of photograph edit brightness and contrast and make other changes according to your whims.

Digital cameras can be of various types. The first in the category is the video camera which is mainly used to record moving images. Then you have digital still camera or live preview cameras. These cameras are usually of two types, compact and bridge. Compact digital camera has small zooms and is characterized by easy focusing and easy operation. They usually have a built in flash. Bridge digital cameras have super zoom lenses and are capable of taking good images.

Then we have digital single lens reflex cameras with a mirror and reflex system, digital rangefinders which is nothing but a camera that has a rangefinder and the professional modular digital camera system that is a very professional camera with different modular parts like grips, winders etc to suit different purposes. These types of cameras are usually used for commercial purposes in studios as they are quite big and bulky.

With a wide variety of digital cameras available in the market, it is obvious to get confused as to which will be the best-buy amongst them. However you need to understand that each camera has its unique function and specialty and you need to check out each one to determine your pick. As for example, if your purchased camera is going to be a gift then you need to know which type of digital camera will be suitable for the person. For instance, teens will obviously like cameras that are funky and cool, while mums will be delighted to get cameras that will allow easy image sharing for family pictures.

Before buying a digital camera it is important that you get your basic information right so that you can get the best deal. There are lots of factors that you need to consider like the resolution of the photograph and the size of camera. Another important consideration is the Digital Camera Storage or Memory Cards. Semi-professional photographers would also like to consider having a decent Digital Camera Zoom.

Last but not the least, after you get your brand new digital camera then learn about the basics of its maintenance and operation. Get acquainted with its various features; learn how to share your images with friends and family and steps to take to troubleshoot your camera.

How to Find the Best Digital Camera

Friday, August 1st, 2008

Nicholas Tan asked:


It seems that every month, if not every week, different manufacturers are coming up with the latest digital cameras to entice potential clients. And it’s just not working for us!

After spending sizeable amount of time at the mall figuring out which is the best digital camera for us, we finally have enough money to buy for that eye-popping, 7 mega pixel, 10x digital zoom, potable, candy colored, up to 512MB expandable memory of super hi-speed SD memory card and not to mention very portable, (that will be the envy of almost everyone we know). We march to the mall armed with our life savings and lotsa pride in ourselves, when we pass by a new display – an eight mega pixel, up to 1G expandable memory, with built it mic and stereo surround, video playback capable, with 22 scenic modes kind-of-camera. And we sigh because the producer of this amazing gadget claims that this is the best digital camera yet out in the market. And so as we always want to have the best, armed with our life savings and a few credit cards, we buy the “best digital camera.” But then again, that doesn’t last too long, after two months or so, there’s another “best digital camera.”

And so it confuses us. What makes a digital camera, the best digital camera?

Well, there are certain factors to consider when looking for the “best digital camera” for us.

MEGAPIXELS. One of the most important features of digital camera to make it into the best digital camera category is its mega pixel property. The higher the mega pixels the better the actual photograph will come out. A mega pixel is equivalent to one million pixels. The resolution of your image is based upon the mega pixel property of your camera. This means that as you enlarge the picture, you would get more detail and less blurry colors.

LCD SIZE. The best digital camera will always have a large LCD to help you frame your subject without having to squint to the viewfinder. This is also helpful when reviewing your images, some cameras enable touch up and editing features with its LCD. A 1.5-inch display is average, a 2-inch LCD display is good, but the best LCD size would be 2.5 inches or higher.

ZOOM. Most digital cameras have both digital and optical zoom. A higher optical zoom is always better than a higher digital zoom. Digital cameras are usually furnished with optical of between 3x to 10x. The better the optical zoom, the higher it climbs up to the best digital camera category.

MEMORY CARD. Always make sure that your memory card is the right one for your digital camera. There are different types of memory card like the xD, SD, Flash card and the likes. And these types of memory cards go with certain types of digital cameras. of course memory storage is also up there in choosing the best digital cameras. Choose the size of memory that you need, if you’re a photo junkie, you might need more than 32MB. Memory cards can go up to 1G.

The key point to find the best digital camera is to find one that will best fit you and your lifestyle. Don’t just buy the latest or the one that claims they are the best digital cameras out in the market. You wouldn’t want to buy a DSLR and use it with your home activities or family outing and have to lug it around?! Or you don’t want to buy the latest point and shoot camera when you’re serious about being a professional photographer. (Of course, you can use this for starters, but if you’re not a novice photographer anymore, you wouldn’t want to get this kind of camera.)

Actually, the best digital camera is the one that you will enjoy and use. Not the type that you’ll just leave rotting in its box or after a few weeks of usage or so, up there in the attic.



Digital Camera: the Future of Cameras

Saturday, July 26th, 2008

Nicholas Tan asked:


Basically a digital camera is a deice use to capture pictures without the use of films. Unlike the conventional camera, the digital camera does not rely on mechanical and chemical processes. It has a built in computer and records the images it captures in an electronic form. Having and operating one does not even require the use of electricity.

Since the images that a digital camera captures is in electronic form, it is a language recognized by computers. This language is called pixels, tiny colored dots represented by ones and zeros that make up the picture that you just took. Just like any conventional cameras, a digital camera is furnished with a series of lenses that focus the light and creates the image that you want to capture. The difference here is then; a conventional camera focuses its light on a film while a digital camera focuses the light into a semiconductor device that electronically records the light. Remember the built in computer, it comes in here and breaks this information to digital data resulting to all the features of the digital camera.

Another feature of the digital camera is that it has a sensor that converts light into electrical charges. A charge coupled device or CCD is an image sensor that is found in a digital camera. While other low-end digital camera use complementary metal oxide semiconductor or CMOS as an image device, it can still become better and more famous in the future but most engineers are do not believe that it can replace the CCD for higher-end digital cameras.

A collection of tiny diodes, the CCD gathers electrons when they are struck by photons or the light particles. Each diode or photosite is sensitive to light, meaning that the brighter the light, the number of the electrons gathering will be larger

The price of a digital camera nowadays have been depreciating, one of the main reasons of this is because of the introduction of CMOS image sensors, this is because CMOS sensors are less expensive and are easier to manufacture than CCD sensors. A CCD and CMOS sensor works the same way at first, by converting the light electrical charges into photosites. Simply putting it, is to think that a digital camera works in such a way as thinking that the millions of tiny solar cells, each of which forms a part of the whole image. Both CCD and CMOS do this task using different methods.

When shopping for the best digital camera, take note of these key features.

Image quality. Check the resolution of the camera. The higher the resolution, the more thou will be able to enlarge your picture without the grainy or the out-of-focus effect that we all want to avoid.

Lens. Choose a digital camera with better digital zoom. The digital zoom of the camera will enable you take the pixels from the image sensor and incorporate them to make an image.

Power. Always opt for rechargeable batteries, they can always come in handy, plus you don’t waste as much money on the disposable ones.

Options. So you can brag to your friends how good a photographer or artist you are. Or choose the one that gives options that best cater to your lifestyle, so you won’t ever whine how you never get the right pictures.

Memory. If you’re a photo freak, be sure that you have enough memory in your camera to take all the wacky, freaky, funny and just about any photo you can. Think 512MB if you’re a photo junkie and takes pictures of just about anything.

Computer Interface. Always make sure that it is compatible with your PC, laptop, palmtop or whatever your local picture printer software is, you don’t want to go running around the whole state or the country looking for a computer that’s compatible with your digital camera, wont you?!

Physical. If you are going to be bringing it everywhere, choose a handy and portable digital camera. This way, it won’t always feel as heavy and bulky as those cameras that you see professional photographers are always dragging on their neck. Don’t they ever get tired of that?!

These are just the basic things you have to look for in a digital camera when you buy one. A digital camera is so great that it is quickly replacing all conventional cameras in the market, with all its technology and portability, truly the digital camera is the future of cameras.



Trusting Digital Camera Reviews

Friday, July 11th, 2008
digital cameras
Nicholas Tan asked:


Digital camera reviews are abundant not just online but also in the newspapers, magazines and even TV shows. We often wonder why most digital camera reviews always praise all the digital camera out in the market, that’s why we end up getting confused on which product to buy or get our loved ones.

Here’s one thing you should never trust regarding digital camera reviews – never trust press releases or reviews that are directly from the manufacturer or advertising office that is directly connected with producer of the digital camera. Why?! Well because these digital camera reviews are never too truthful, or they just give out the good points about their products. I mean, what would you expect, supposing you own your own line of digital cameras and to boost your sales, you release digital camera reviews about your products. Of course you wouldn’t point out the bad things or the glitches of your product in your digital camera reviews, because that way you will never be able to shoot up your sales. Press releases or digital camera reviews from manufacturer are always half-truths. Haven’t you had any experience with that?! I mean, that just doesn’t go for digital camera, remember that brush-blower thingy that you bought over the internet that says it would work tremendously for your hair, but ended not working for your hair after all. Press releases are press releases, meaning that they are aimed to get people to buy the product or to give the product a better name.

On more thing that you can never fully trust are home shopping networks and advertisements. As much as press releases, they pretty much pose the same claims about their products. But hey, don’t trust me, you can always get them and return them after proving to yourself that it doesn’t work. Never mind the time and effort that you’ve wasted, you chose to listen to a half-truth digital camera review, that’s what you get for that.
