Red eye- web formats

PNG

JPG

GIF

I knew there were different extensions for pictures but i never knew about the differences about them. They are very different from each other. I see that PNG is extremely clear, brighter, and crisper than the others. The difference is less in the JPEG format (better) but more noticeable in the GIF format(worse).
The shadows in the pictures are clearer and the difference in the color is obvious therefore the PNG format is the best, JPEG is not so bad but the GIF is the worst one in this case with less colors.
In the GIF format is nearly like an old cell phone camera (VGA, less colors).
So in this case PNG is the best!!!
