Cropping photos and saving - Resolution Issues

Hi Miles, and a warm welcome to the forums! 🙂

Whew, found a way to do it finally.

Of course Aperature, Photoshop, or Acrobat Professional will do it, but for frre I found Seashore...

It can Read PDFs at resolutions up to 900dpi, then save them as a TIFF, (among other things), which are hi rez... just had to show Alpha channel and Invert them.

I just wanted to observe that if the images in the PDF itself are only 150 ppi (as might well be the case in a document intended primarily for viewing on screen or for printing rough proofs) there’s very little point in trying to save them at any higher a resolution. Do you know that the originals are at least 300 ppi? Note also that images in PDFs are often JPEG-compressed, with the result that they contain considerably less true detail than their nominal resolution would indicate.

AHA, good additional points! 🙂

I take too much for granted sometimes.
