The "Fine" print is the one where I've selected out of the series, after I've decided to stop. It is NOT always the last one ... I think that there is something of "overworking" involved.
Come to think of it... It is usually the second or third print, out of as many as twenty prints of the same image.
Note that I've said, "Fine". I am firmly convinced that there is no such thing as a "perfect" print, nor will there ever be.
We just have to realize that we MUST stop somewhere.
