Your answer seems a bit strange to me. While I on very rare occasion
crop an image to specific pixel dimensions I more frequently crop an
image to specific aspect ratios (w/o pixel dimensions) or, if I'm
intending to print, then may do the crop with a specif resolution
setting or re-use the dimensionless crop and force it into a specific
size and resolution. For example, an image cropped to a dimensionless
2:3 ratio may be reused (with resolution resizing) to make a 2x3", 4x6",
6x9", 9x12", etc, etc. without ever having to up-rez anything.
PhotoShop certainly doesn't do it but does Lightroom store cropping and
resizing info in sidecars as well without altering original images? I
suspect no.
