[QUOTE="WayneF, post: 447297, member: 12496"] Image size is only dimensioned in pixels. File size is dimensioned in bytes, or KB or MB or GB. But that seems way small now. It looks like ONE original D7100 image, slightly cropped. If it is four, then it is tremendously cropped. 5834x3829 pixels is 22,338,386 pixels (22.3 megapixels). D7100 takes 24 megapixel images, 6000x4000 pixels. 22,338,386 pixels * 3 bytes per pixel for RGB is 67,015,158 bytes data size (uncompressed), JPG files might be 1/5 or 1/10 that size. Four of them might be nearly 4x that (less due to panoramic overlaps, cropping, etc). I don't see any way to compute 1 GB. Maybe 100MB or 200MB? But four is not over 1/4 GB. This one is less than 100MB. No one is going to tell me I went the wrong way in original message, dividing instead of multiplying by 1.024 three times? My blunder, brain not in gear. Worse, I just did the same thing here. :) Corrected here now. [/QUOTE]
