Andy,

You really don't need to print photographs at much more than 240 DPI,
unless you have very small text or tiny details that you must keep as
sharp as possible. 300 DPI many be better yet, but no more is really
needed for your average photograph. The stairstep method is a HAIR
sharper than genuine fractals.  Fred now has a stairstep action for the
D30 and D60 cameras. It works better than genuine fractals. And his D30
and D60 sharpeners are better than any other sharpen method I've yet
tried.  No, you don't have to have a digital camera to take advantage of
stairstep. The files aren't all that huge, especially for a print that
is only 10x15. Unless you are in 16 bit, you should only have a file
size of around 24 or 25 megabytes at 2400 DPI. You would have a very
large file if your file size were 480 DPI. You really don't need to
print with that high a file size.

You shouldn't sharpen the image until you've got your final size from
the stairstep program.
