Megapixel Calculator Instructions: This calculator will compare two cameras
with different megapixel amounts or aspect ratios. It will tell you the
difference in terms of resolution and also of print size.
Simply enter the number of megapixels of the first and second camera, as well
as the aspect ratios for each. Normally there are only two aspect ratios
"4:3" and "3:2" but these have to be entered as a number. Enter 1.333 for 4:3
and 1.5 for 3:2. Of course if the camera produces an image with a different
aspect ratio then you can adjust the aspect ratio accordingly.
CAUTION! Please note
that this comparison assumes that image quality and things that affect it (i.e. sensor technology, individual pixel size,
dynamic range, noise, color accuracy, diffraction, lens quality, internal processing, etc) are comparable for both
cameras. In real life this is often not the case. This tool represents only the theoretical maximum gain, or loss, in resolution.
