I don't get why people are calculating cropped file size. To get to 1x1 you will only be cropping in one dimension. You will still be able to print/view just as large as the smaller uncropped dimension would have allowed.
You lose a part of the frame when you crop, so you end up with less resolution to print with.
Yes but only on the long side.
Let's say you were happy to print a GFX image at 40x30 inches, if you crop to 1x1, you can still print 30x30 inch images, with the same resolution. So I would just work out how large you can print any image from any format and be happy with the resulting quality, and then look at the short dimension. That is the size you should be still happy to print at.
If using a 3x2 format and you were happy to print at 30x20 inches, then you should be able to print at 20x20 inches with no loss of quality.
This ^ .
First question is what PPI requirements do you desire / require for resolving quality.
If you're a 300 PPI or a 200 PPI, then that sets the stage for your max print.
With the short side of the GFX 50R at 6192 ... call it 6000 for easy math ... then 300 PPI will yield a 20x20, whereas a 200 PPI will yield a 30x30.
Meanwhile, the 100S has a short side of 8736 ... call 9000 ...then 300 PPI will yield 30x30, and 200 PPI will yield 45x45.
The salient point is that for 1:1 ... short side is the limiting dimension (whether it starts at 3:2 or 4:3). I reckon one could say that the short side is the limiting dimension, regardless of format.
