5 or 12 megapixels

I am just taking pics to be displayed on the screen, not for printing. I have a 12 megapixel cam, but it seems like overkill. Do you think using the 5 mp option is good enough, such as posting pics to social networking sites.

Most people don’t pay much or any attention to the number of pixel, but whatever you need or whatever you are happy with.

I am not familair with the CAM, but I can tell you that the number of PIXEL doesn’t mean much, but it often base of your toy. Example

– 5MP from a cellphone may not as good as 1MP of P&S camera

– 15MP of P&S camera may not be as good as 5MP of DSLR camera.

– 20MP DSLR with cheapie lens may not be as good as 10MB DSLR with best lens. Of course a good camera is capable of taken top-notch image with cheapie lens, but I am talking about normal use *not* special setup.

In general, you should pay more attention to the SIZE and acceptable quality you need. I dislike low-rez image so all my photos always saved as MAX quality (example with Photoshop I save at Quality = 12)

It’s a Polaroid i237 digital camera. I think it takes great pics.

If I upload pics to facebook at 5mp, it resizes it to fit on the screen. When I view the same pic in Photoshop (without facebook), it shows it at about 25% to fit on screen.

And the screen size may have nothing to do with the quality or number of pixel. I do know what Mega Pixel is but I do not understand what you mean by 5MP vs 12MP photo. Because they don’t mean much or anything.

Also, you can have 1M size photo to fill a whole large screen, when the 8M size may not. The displaying depend on the resolution (screen resolution not photo) or the W x H, when the quality depends on the W x H x PPI (and Compression)

Most graphic viewers should give you the option to FULL-SCREEN display (with option base on Ratio or stretch-to-fit), and fit the program displaying window. So, what you are saying doesn’t mean much or anything.

– WEB, some browser doesn’t have the option to fit-displaying-screen so with a large resolution it may display only smaller part of the whole image. Some browser with option to shrink whatever resolution to fit the displaying window (of the browser not monitor)

– Many Photo Hostings often have option to display either small, medium, large, extra_large and ORIGINAL etc..

– Web, web owner has option to display inside TABLE (frame).

Now talking about FACEBOOK which I have heard but never view any FaceBook to know much about it. But if you want to know more about web browser displaying then read below.

– If you want a smaller displaying then

a. Set the W x H (like 4×6 or 8×10 for example)

b. If you want to reduce the size for web displaying then. Lower the QUALITY, and also lower the PPI then you will have a smaller displaying

IOW, with two 10MP camera they may have the similar file size but may not have the same displaying size. Example if 1 has the PPI=50 and other has PPI=100, then the one with PPI=50 will display much wider than the PPI=100

Example, if you have (1) $100 bill in your wallet then it’s pretty flat, comparing to stuff (100) $1 bills in the wallet. Same quality but different QUANITY
