Hi Ron,
Thanks for your post. Accordingly I had a look into this...
the ideal crop box is only achievable unconstrained. If I try to re-create a 'custom ratio' of similar size (as it is the only way to create a preset), I can save it, but when I recall the saved preset for the next image, the crop box jumps in size to something different. All the images are same-size.
what I am trying is to move an always same-size constrained crop-box over different images to select only its position (without resampling) – like a cookie-cutter.
is a macro something that could work?
Thanks for your thoughts and time.
