Maybe this will help. I:
I crop at 13" x 18"13" x 18"
, and when I put that (exactly as it is) in to the crop tool, it would crop to an aspect ratio of that size but the image would not be 13 x 1813 inches x 18 inches
. I
I finally figured out that itI needed to put 13
in
x 18
in
into the crop tool 13 in x 18 in and it worked, it needed to know that it was inches. Hope this helps.
