Digital Camera Battery Tips

Battery Conservation Tips

Are you always running out of battery power just before you take that perfect picture with your digital camera? Here are some

tips to conserve your batteries when you are out “snapping away”.

1) Turn off your digital camera when not in use. If you are in a situation where you must snap pictures quickly, this may not

apply as turning digital cameras on and off take a few seconds, and may cause you to miss a picture-taking opportunity.

However, if you are taking a leisurely stroll and can afford a couple of seconds before snapping a still subject, by all

means, conserve your digital camera’s energy!

2) Many digital cameras have a regular viewfinder and an LCD viewfinder. While the digital LCD viewfinder has its benefits,

it can drain battery power. Turn it off when applicable and use your regular viewfinder for taking pictures.

3) Don’t stop after taking every photo and look at the picture in your digital camera’s playback mode. Granted, you sometimes

need to look at photos immediately after shooting them in order to make sure your exposure is correct, the lighting is ok,

etc., but doing this does use up your digital camera’s battery power.

4) If you are using MicroDrive media, be forewarned that these miniature hard drives may take up quite more power than

Compact Flash cards.

Taking care of you new battery pack

Normally, a new battery pack comes in a very low charge condition and must be fully charged before use. Refer to the user

manual of your portable electronic equipment for charging instructions. A new battery pack needs to be fully charged and

fully discharged or “cycled” as much as five times to condition them into performing at full capacity. Your equipment may

report a fully charge condition in as short as 10 to 15 minutes when the new battery pack is being charged for the first

time. This is a normal phenomenon especially for Nickel Cadmium (Ni-Cd) and Nickel Metal Hydride (Ni-MH) chemistries. When

this happens, remove the battery pack and let it cool

down for about fifteen minutes then repeat the charging procedure. “Conditioning” (fully discharging and then fully charging)

is necessary so as to maintain the optimum performance of a battery pack, and is recommended at least once a month

particularly for Ni-Cd and Ni-MH batteries. Failure to do so could result in reduced charge capacity and can significantly

shorten the battery packs useful life. Lithium Ion batteries do not require conditioning. It is normal for a battery pack to

get warm when charging and during use. However, if the battery pack gets excessive hot, here may be a problem with the

portable electronic equipments charging circuit and should therefore be checked by a qualified technician. Rechargeable

batteries undergo self-discharging when left unused for long periods of time. This is normal particularly in the case of Ni-

MH and Li-ion chemistries. For best results, always store a battery pack fully charged. It should be removed from the

equipment and kept in a cool, dry and clean place. The amount of runtime a battery pack produces depends on the power

requirements of components in your electronic equipment.

Don’t let under-charged batteries keep you from taking great photos.

If you infrequently use your digital camera, you may think that you after you use your digital camera, recharge your NiMH

batteries, wait a few weeks or months, then use your digital camera again, that your batteries will be charged and you’ll be

ready to snap photos, right?

Oops… Do that and you’ll be stuck with a non-functioning digital camera or one that just blinks a picture showing a dead

battery.

Rechargeable batteries don’t stay charged forever. They tend to lose a little bit of their power every day. If you charge

your batteries and frequently use your digital camera, you will probably never notice this loss of power. However, after a

couple of weeks, the power loss may be noticeable, and after a couple of months or longer of non-use, those once ready-to-go

batteries may have lost enough power to make them unusable.

Don’t get caught in this trap. Always charge your batteries before every trip, and make sure to use a battery charger with a sensor that prevents over-charge.

How to Buy Discount Digital Cameras

Wednesday, October 29th, 2008
digital cameras
Russ Snapper asked:


Many brands of discount digital cameras are available from manufacturers such as Kodak, Fuji, Nikon, Olympus and Canon amongst others.

Why these cameras are discounted?  The reasons could be like they have been over purchased with a lot of stocks left or it could be a means of making you enter their store. Websites use discounted items to grab your attention to their website many times. Online purchasing has emerged as a large market and it can save some money to the company when you purchase online. As expenses such as opening a store, paying out salaries for employees, purchasing shelves and other fixtures are not incurred, these savings can be passed on to you to some extent.

By saving money on the purchase of discount digital camera, you will feel great as by not paying the full price, you still have the same quality. The digital cameras are exactly the same as the difference here exists only on the price. Hence, why should you pay an expensive price as you can get the same camera when you purchase it on a discount?  With the money thus saved, you can buy other great add-ons for your digital camera.

Finding discount digital cameras is easier over websites. The question is which digital camera to choose. You can find discount digital cameras from most major digital camera manufacturers. You should have a basic idea of the options, features and brand name of the digital camera you want to buy. You can also find from sale bills and newspapers about different types and brands of digital cameras along with the prices offered at many stores. Some times, though the deals are advertised over the web, they may not have them in their stores. Earlier the digital cameras had one thing in common when compared with non-digital cameras, (i.e.) an expensive price tag. However the cost of digital cameras has dropped so much recently that you can purchase a digital camera for less than $250.

When buying a discount camera, you have to be aware of at least the buzzword ‘Megapixel’ related with digital cameras. Megapixel refers to the number of pixels available per million or the resolution of the image. This is important to be considered because Megapixel directly relates to the image quality obtained. The factors such as budget, mega pixels, exposure control, battery life, user controls and Zoom lens are all important while making a choice of a camera and to get the best out of it. Knowing these features will save you time when you start looking for a discounted digital camera.

You have to understand also the type of software that is needed for the discount camera you have planned to buy. Because all digital cameras do not use the same software for storing or to transfer the photos from the camera to the computer. Make sure that the software supplied will be compatible with your computer, without the need for upgrading your older computer for the sake of having the photos on your computers.

If you don’t have an idea of the features you need, you can also then search by brand name of the digital camera and read all about the various models offered. Still, Price should not be the only factor when you shop for discount cameras, but also certain basic features.

Russ Snapper asked:


A Mini digital camera can be a best travel companion if you love to travel and are constantly on the move. The mini digital camera is most preferred now for travelers and photographers because of its small and unique size and easy to use features. To use this ultra compact camera, you don’t need to be a professional photographer. But you can be a good photographer with the enhanced resolution offered by the small sized camera that improves the quality of ordinarily photographed items also.

The availability of the following features can be checked out before you buy a mini digital camera.

Megapixel rating: Giving attention to this rating helps you to estimate the volume of information stored with each photograph taken. Resolution of the photographs depends on the Megapixel rating. Mini digital cameras have higher Megapixel ratings for storing more information and for getting great quality enlargements. For most of the pictures that fall under 4 x 6, a minimum of 3 mega pixels will be good for your camera.

Batteries: Battery usage is to be determined before you buy a mini digital camera. With a set of batteries, most bad cameras produce around 50 shots. However ensure that your enhanced mini digital camera produces around 500 shots with a set of batteries. Rechargeable AA batteries can be used for a longer duration of time and is beneficial and economical in the long run.

Other Features:It is advisable to choose a mini digital camera that is fast. When the shutter is pressed, time is taken for processing an image and this time gap varies for different cameras. Some cameras have a time gap of 5 seconds and for taking a second snap, you have to wait for that time. Due to shutter lag also, time can be consumed. Shutter lag is the time taken for the auto focus feature to terminate and then trip the shutter to start. Therefore ensure that your mini digital camera is really fast. Also ensure that your mini digital camera is having an optical zoom rate of 5X to 10X for getting better zoom for having close-up shots.

The mini digital cameras have an Inbuilt LCD screen, which helps you to frame the shot before clicking. You can immediately view the picture after clicking. Most mini digital cameras have autofocus feature and you have to ensure that this feature is fast. For a mini digital camera having a zoom factor of 10X and above, ensure that it has image stabilization to remove the shaking effect caused while taking pictures. Mini Digital cameras beautifully capture your moments of joy with least effort.

As an example, we will now look at the features of a Key chain Mini Digital Camera, MiniDIG. Some key features are Flash; Auto Formats; JPEG; White balance; Auto Shutter; Auto Resolution; 640×480, 320×240; Pop-up viewfinder; EV compensation; Auto System compatibility and Windows 98/SE/2000/XP.

This inexpensive, cute looking Digital Camera is a great little device to take along for spot photos for insurance claims or during vacation holidays and serves as an exciting addition to your keychain. This can also be a wonderful gift for children looking to have their first camera.



The Early Digital Camera

Friday, September 26th, 2008

Roberto Sedycias asked:


A digital camera is basically a digital device that enables images to be captured. Digital camera images are stored electronically rather than on film. This process involves converting light into electrical charges, and then translating this back into the image that was seen through the digital camera LCD. Although the digital camera is a recent addition to the world of photography, the concept of the possibility of a digital camera was begun in the 1950s.

The early concept of the digital camera was closely linked to television technology. It began with digital images being recorded on scanners and in the form of digital video signals. In 1951 broadcasting companies were recording images as electrical impulses and onto magnetic tape from their television cameras, and this paved the way for digital camera technology to begin. By 1956 electrical impulse recordings were common practise within film industry, and camera manufacturers began to dream of a digital camera device.

The first record of a patent for a type of digital camera was in 1972 when Texas Instruments patented a camera that did not require film. However, the patent revealed a more analog based design rather than a digital camera, and there is no record of whether the camera was actually created. What the patent does show, however, is that interest towards a digital camera was growing with the idea that the need for film could be removed. A pioneer in the history of digital camera was Steve Sasson, an engineer at Kodak. Digital images were of the moon were being transmitted via satellite by NASA, using a mosaic photo sensor, and he saw the possibility of a digital camera for commercial use. In 1972 he began to group together available equipment used within the film industry to create an image digitally rather than on film.

Central to this early concept of the digital camera, and still used by digital cameras today, is the Charged Coupled Device. The CCD detects light and colour intensity and then converts this information into electrons. The value of each cell in the image is then read, and converted to binary format to make the image computer compatible. Steve Sasson produced his first digital camera image in 1979. The image took a total of 23 seconds to take, and a further 23 seconds to read from the playback unit. Although the digital camera image was less than perfect, it showed that the digital camera was a possibility. Kodak had developed a camera that developed picture from light, but it was never manufactured for the public.

The first camera to be marketed was the Sony Mavica electronic still camera in 1981. It was not a true digital camera as the image was recorded on mini disc, and then attached to a television or video. It was more a freeze frame video camera but it greatly influenced people`s attitude to the recorded image. It made public the possibility of a camera that stored images using techniques other than film. It still used more television technology but was the first hand held with the general idea of digital camera usage. Cameras that could transmit images via satellite became popular, but were used by the media only due to the expense incurred. The possibilities were becoming apparent and images were used for news coverage. The first camera for general use with a computer was the Apple Quicktake 100 camera which appeared in1984. In 1986 the Canon RC-701 was used for coverage of the Olympics, with quality images printed in the newspaper. This showed the possible quality, and the desire for the digital camera was born.

The first mega pixel sensor was invented in 1986. It contained 1.4 million pixels and was suitable for a digital camera image measuring 5×7 inches. In 1987 accessories for storing, printing, manipulating, transmitting, and recording digital images came onto the market, with the Fuji DS-P1 arriving in 1988. This is arguably the first true digital camera as recognised today, boasting a 16MB memory card. With the arrival of JPEG and MPEG standards in the 1990´s, the face of the digital camera was changed for ever. Kodak marketed the first readily available digital camera that met all standards, with the Kodak DC40 in 1995.

Cheap Digital Camera Varieties

Sunday, September 14th, 2008

Russ Snapper asked:


Major manufacturers such as HP, Kodak, Samsung and Fuji offer cheap digital cameras too. Cheap digital cameras generally have lesser advanced features such as multiple file resolution settings, optical zoom, optional image file type settings, advanced automatic exposure meters, large capacity memory cards, replaceable lenses and waterproofing. Most of the cheap Digital cameras are of point and shoot type.

Image quality is related to Megapixel rating directly and the handling of white balance by the camera. If you want to post pictures on a web site, email pictures or store them on hard drives, cheap digital cameras with a 1.3 Megapixel rating are more than satisfactory. If you want to have images of portrait quality, then you have to look for cameras with 3 mega pixels or higher ratings.

Due to the Megapixel rating, many cameras are expensive. The higher the rating of the mega pixels, the larger the photographs. However, cheap digital cameras will not come with a lot of mega pixels but still may not be necessary at all times. You don’t require a lot of memory if you don’t need very large pictures. Most cheap digital cameras will print eight by ten inches and this is what many people may need.

However, cheap digital cameras can be an excellent gift for young children. If you want to get started in digital photography and if you are not sure how to take it forward, cheap digital camera is an excellent choice. It can also be a spare or a good second camera for keeping in your boat or car for taking advantage of capturing some unexpected photo opportunities. You need not spend a large amount of money for buying a brand new digital camera just for opening up the box and reading the instruction manuals once but not interested to learn all the features of the camera. Still, most people often get discouraged from buying a used digital camera as they feel that they can get great pictures by getting the most expensive camera available. There are many cheap digital cameras available for sale and you may not require all of the fancy features and thus can save money.

You have to think about the overall picture quality you get from a cheap digital camera. It can take amazing pictures outside and if you try to take some inside the house, the quality can be poor. Though you can repair them with some photo editing software, you will not get professional photograph pictures. But you can have it for your basic picture taking needs.

You can look for cheap digital cameras available on a number of websites and can read reviews and blogs from some people who have tried with such cameras. This is the best way for deciding the type of cheap digital cameras suitable for your needs. Many sites have listings of sales, coupons, bargains and cheap deals.  You can select a specific deal offered on a cheap digital camera sent to you via palm text message, email, RSS feed or mobile phone amongst others. Such alerts on deals can be customized to enable you to select for receiving only cheap digital camera offers from a particular brand or vendor in an area. You can also customize such that cheap digital cameras can be classified based on the price as everyone has a different budget.



Few Facts Of Digital Cameras

Sunday, September 7th, 2008
digital cameras
Roberto Sedycias asked:


A digital camera captures images in a digital format, unlike a conventional camera, which captures images using a photographic film.

History:

Using a mosaic photosensor, Eugene F. Lally of the Jet Propulsion Laboratory first showed how still photos could be produced in a digital domain. An engineer at Eastman Kodak, Steve Sasson, used solid-state CCD chips to build a prototype digital camera having a resolution of 0.01 megapixel, and recorded black and white digital images to a magnetic cassette tape. With this prototype model, Steve took the first image in December of 1975 taking 23 seconds to capture it.

In 1988, Fuji DS-1P became the first digital camera that captured images as a computerized file. However, the camera never entered the U.S. market. In 1991, Kodak DCS-100 was the first commercially available digital camera, which used a 1.3 megapixel sensor. With the advancement of technology, modern digital cameras have become multifunctional and are now capable of capturing audio/video and still photographs.

Benefits:

1 – You get superior image quality. Digital cameras can offer good to excellent image resolution.

5 – You can email the pictures to your friends. You can send the pictures by email to your loved ones.

6 – You can store the images in CDs or hard disk. Once the pictures are transferred from digital camera to the computer, permanent storage on a CD or hard disk is possible.

7 – You can take the camera in your pocket while you travel. The small size of the digital camera makes traveling with it easy and a pleasure.

8 – You can move in close to your subject. Zoom lenses offer close-ups of your subject with sharp focus. You can take very good close-ups of flowers, bugs, stamps, coins, etc.

9 – You can rework the image in a computer. Any photo editing software can rework the images taken.

10 – You can take good pictures even in low-light situations. Due to flexible over sensitivity or ISO equivalents, digital cameras can easily take detailed pictures even in low-light conditions.

11 – You can take quality still photos of moving objects. Sports and fashion photography can be easily accomplished due to the fast burst rate of digital cameras.

12 – You save money. There is no need of buying photographic films, developing them into negatives and positives. Moreover, the batteries are usually rechargeable lithium-ion batteries, which last a long time.

13 – You can choose as per your needs and fancy. Many models are available like standard digital camera, underwater digital camera, waterproof digital camera, compact digital camera, and the professional digital camera.

Storage Media:

Digital cameras use memory to capture and store images. Some of the storages media used are onboard flash memory, 3.5″ floppy disks, video floppy disk, PCMCIA hard drives, CD or DVD, CompactFlash memory cards, Microdrives, Memory Stick, SD/MMC, MiniSD Card, MicroSD Card, XD-Picture Card, SmartMedia, and FP Memory.

Power:

Digital cameras consume a lot of power, which is supplied by powerful, small in size batteries. Batteries are broadly divided into two groups, namely, off-the-shelf and proprietary. Off-the-shelf batteries are like AA, CR2, CR-V3, AAA, and RCR-V3. They are lithium-ion (Li-Ion) or Nickel metal hydride (NiMH) batteries. Standard AA non-rechargeable alkaline batteries either do not work or work for only a very short time in most cameras.

Proprietary batteries are built as per the manufacturer`s custom specifications and are usually available as aftermarket replacement parts. Generally, lithium ion batteries are widely used as proprietary batteries for digital cameras.
