[QUOTE="WayneF, post: 555506, member: 12496"] 1. Yes, your crop would have more pixels remaining from the larger image. If you cropped both to 50% of the image dimensions, the larger image would still have larger dimensions than the smaller one. 2. Image size is 4608 x 3072 pixels. Megapixels is 4608 x 3072 = 14.155776 megapixels (the total count). 3. RGB data size is 3 bytes per pixel, 14.1 mp x 3 = 42 million bytes. Megabytes is a number nearly 5% smaller, 40.5 MB (still the same bytes, just a different numbering system). Then the JPG file compresses the data to a much smaller file size (but when opened into computer memory, it is still the same 42 million bytes again).
