Oh wow, how do I count the ways and where to even start. Just off the top of my head, the ability to
EASILY- Resize, change aspect ratio
- Create layouts with multiple prints of various sizes on a page
- Invoke the highest quality interpolation algorithm(s) available so that almost any decent digital image can be printed to any reasonable size
- Adjust color balance, lighting and contrast
- Do all of the above without ever destroying, or altering the integrity of the original image
- Manage and organize photos into albums without having to actually make multiple copies of the images
- Instantly recall and revisit any photo page you have ever printed
- Do all the pixel peeping you want to, even compare two versions side by side
I have barely gotten started
