Does anyone know the best digital camera with the cheapest price? and doesnt run off of batteries? Thanks! :)?

I do not know of any digital camera that does not require electrical power to operate. Usually this comes from batteries, but most cameras have optional power cords that can connect your camera to a wall outlet. I don't think this is what you are really looking for, though.

The only cameras I know that can operate without batteries are film cameras made prior to the 1980's that were all mechanical. The light meter won't work (in most) without a battery, but the basic camera functions will still work. There are a few very high line professional 35 mm film cameras still made today that will operate without batteries, but they are not even close to "cheap" in price.

The following questions will help you get a better idea of which digital camera will be best for you:

What are you looking to accomplish? What are your goals? Do you want to simply document the life and times of your family, for example, or do you fancy yourself become a digital artist?

Do you want to print your images? In large sizes? (Look for high resolution)
If you are going to print, what kind of output device (i.e. printer) will you be using and what are its resolution requirements? (Again, look for resolution)

Do you only see yourself publishing your images on the Web or emailing them to friends? (You don't need much resolution - don't worry about it)
Will you be taking this digital camera to Europe or around the world? (Look for lots of storage)

Do you own a laptop? (Look for a CompactFlash or other PCMCIA storage device)

As taught in our Top Ten Tips, the cardinal rule in photography is to move in close to your subject. Will you always able to get very close to your subject? (If not, be sure to get a digital camera with a good telephoto zoom lens)

Will you be taking pictures of small items like stamps, coins, bugs, flowers, etc? (Look for a digital camera with a macro feature)

Do you already own Photoshop or Photoshop Elements? (Then you might want to just get a camera with a Photoshop plug-in)

Do you prefer shooting digital photos over reworking them on the computer? (Then you might want to go for a camera with a popular, easy-to-use software program)

Do you foresee yourself shooting at night, at concerts, indoors, or in other low-light situations? (Then get a camera with flexible over sensitivity or ISO equivalents)

Do you foresee yourself shooting sports, fashion, or anything else that moves quick? (Then get a camera with a fast burst rate)

Do you want to make sure that the money you save on film and developing doesn't just end up getting spent on batteries? (Then you might want to get a camera with rechargeable Lithium-Ion batteries or some such similar set-up)

How much money do you have to spend? (Look for a bank that will refinance your home...)

Why Resolution Matters

Especially if you are going to be printing your images, you will want to get as much resolution as you can afford. This is often expressed as MP (megapixels) or as a figure such as 1024 x 768.
Unfortunately, this aspect is the one most closely tied to the price of your camera because this aspect is dependant upon the high costs of electronic chips.

If you are one of the lucky few who are only going to be using your camera for Web site imaging, emailing, or other screen-output applications, you can relax; most of these cameras will offer more resolution than you will ever need.

Let there be light (on the subject of resolution) 漏Jim Miotke

Note: It is important to find out if the resolution of a digital camera is optical or interpolated. Usually, interpolation is the digital imaging equivalent of cheating at poker; you may walk away with more but you will never feel good about sharing your work with others.

File size is just another way of estimated the quality of the camera's output; if the camera can capture more information, odds are good that the quality will be better, especially when printed.

However, resolution is not the only factor in image quality. In order to make outstanding images, you need a way to store lots of photos, a good lens, good software or compression algorithms, burst rate, sensitivity options, and battery consumption... among other camera features.
