remember

When I'm told that this or that camera has 6.1 MP or 7.1MP, what is the amount of area that the MP resolution rating is for? Is it for the size of the screen of the camera? or is the MP resolution rating only for 1 square inch of picture area?

Wikipedia does a much better job than I could ever do... (or have the effort for...)

Or a comparison, a 5MP image is just under 8x10" printed at 300dpi(basically high resolution/photo quality)

MP accounts for the resolution of the prints. So basically, the bigger it is, the bigger you can make your prints. More pixels will accumulate on a picture horizontally and vertically to make the picture. So the more pixels, the bigger the picture can be.

If two camera's are both good camera's and taken at a certain resolution both camera's can take, you probably wont be able to tell the difference if one was a 3mp and one was a 7mp. It has nothing to do with the screen size of the camera, that's something else; such as in inches (2" lcd screen vs 3" lcd screen).

To DCIScouts:
Thanks for the wikipedia reference. It was very complicated, so I just bought my camera today with a 1 month return policy. So hopefully I'll finish reading that before I change my mind on this camera. Its a Kodak C875 (5x optical zoom and 8.0MP) for $200. The only other slim/compact I could find was 10.0MP with 6x zoom but it was $500. Hopefully I made the best "tech-time dependent" buy I could. It seems good, except the LCD screen is very grainy, but produces good pics once uploaded on to a monitor.

To The Other One:
What you say doesnt make sense. If 5MP produced 300dpi for a 8 x 10 photo= thats 80inches times 300dpi, which is only 24,000. So this whole thing doesnt make a lot of sense to me. I think that 8MP is actually way more than I need, because I couldnt even send someone more than 4 photos due to the size of the res. Now Ive got to figure out how to reduce the res on this pictures.

To computerhakk:
I understand what you say, but this is the same confusing subject I still cant understand with TV projectors. My cameras LCD screen is 2.5", and when you see the graininess, you'll know there is Not 8MP on that screen size. But what screen size will this camera produce 8MP's on?
If I keep enlarging the picture being produced from a TV projector that is HD 1080p x 1920 res, eventually its not going to be HD. So when these resolution "values" are given, I still dont know what the surface area size was when these resolution values were determined.

Well, MP=megapixel=1000 pixels. 1mp=100x100, 500x200, etc. It just depends what aspect ratio your camera takes pictures at.

Umm..., you're math is way off. MP = 1,000,000 pixels; which also would be 1,000x1,000 or 5,000x200

As for that camera, that's a pretty good choice for the money... There are a few Nikon models that would also be a good choice, but that Kodak is really quite good for a base starter camera.

Also, if you need some more info now or in the future, here's a little guide. Not completely exhaustive, but definitely should get you thinking along the right track:

No...300dpi is 300 dots per inch or pixels per inch...8x10 is a size of printed photo 8inches by 10inches...so u dont multiply thats only with megapixels(how many overall pixels are in the picture)...hopefully that clears that up a little

Reason it's not showing good it supported resolution it takes is because of the camera itself. As good as some of those 300-500$ 5, 6, 7 megapixel camera's are, they are still considered low-end. If you are looking for great quality images, you will have to invest in SLR camera's rather than compact, small, SLR-like camera's. You never want to keep enlarging a picture. You should try to take it bigger, than down-size it. Enlarging it will obvious cause it to lose quality.
