They are installed just under an inch thick, and with advanced functions and high-resolution sensors. Advanced settings include common features such as multiple AF zones, manual settings and scene modes developed.
 
There are some shortcomings of compact digital cameras. Since the sensitivity of a digital camera can be calculated by the ISO, the ISO range is a compact digital camera between ISO 50 and 400 while on the other hand, the ISO range of digital SLR camera varies from ISO 100 to 1600th This makes compact digital cameras are less sensitive than digital SLRs.

If you want to know a few basic guidelines for drawing fair comparisons between a plethora of options available in the market, read the article. It will definitely help you make the best deal for you.

There are many factors that make a particular camera better or worse for you. The pixels, optical, memory, camera size, digital zoom and cost of various digital cameras should be compared well before picking any camera. The important task is to put through a sieve all the hype and get the best digital camera suiting your needs.

But before you start comparing the features of different cameras, it is important for you to make certain basic decisions. They are related to identifying your basic needs and prerequisites for the camera. Decide on why you need a digital camera. The purpose should be well-defined. Ask yourself, is it for taking candid snapshots or for serious photography. If you are buying the camera for clicking pictures for an exhibition or a photo website, the criterion of purchase will definitely change. There are different sizes of models that include compact, miniature and big size cameras. Be clear about the size you need to buy.

Then you may start comparing the specific features of the digital camera. You can compare the quantity and quality of the pixel. The more the pixels in the camera, the clearer and quality pictures it would produce. The pixels are nothing but tiny squares of color and light. Thus to get the best camera, you should have the best pixel quality. The sensor of the camera can be called as its eye. Generally, the digital cameras with larger sensors have better quality diodes, which result in sharp and clear pictures.

You should also compare the digital camera on the grounds of its memory. All the digital photographs require the storage capacity of several megabytes. You should compare the capacity of built-in memory of the digital camera. You should certainly go for the one with more battery capacity. A general guidance principle is to have a battery with at least 256 to 512MB of memory. It is important to check the memory compatibility while comparing the digital cameras.

You can also compare the SLR digital camera with compact digital camera. There are many features that you may find in a compact digital camera but not in the SLR digital camera. It can also be vice versa.

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.
