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
