Use the minimum compression that will give you the file size you need for
your purpose. The more you compress, the more data you lose. Always save
the original. Remember, HD space is something like $.50US a gigabyte
these days, so adding HD space is a pretty cheap alternative.


I can second that.
And 95% quality level really gives you the optimal value to start with.
A 100% doesn't scale to the gain you get for quality and everything less is
covered by the 50 cent/GB (nice value BTW )

Yes, considering that only a very few years ago, a 1GB HD cost $2200!!!!
Amazing!

I agree that you should always save the original. However, isn't that
50cent number ignoring the time/money required to keep things backed up?

"Best" with respect to what?
"Best quality" = least amount of compression
"Best size" = most amount of compression.
Most people select a medium compression value, and that might be OK for you
provided that you do not edit the image very many times.

I just want to scan some camera photos that I borrowed.
I may not have access to the photos again as they will be sent
overseas, so I need a good scan job.
