Mark, what made you think that ? I said that EVEN Photoshop 4 has the
transfer function, meaning you don't need a fancy program to do this. Of
course Photoshop 7 has it as well. I told how to get there, & showed where
to click on the "print" screen (that "screen shot",by the way, has the
Mac's best sound effect).
In fact, checking page 37, I see I mentioned that the screen shots were
from Photoshop 7.
Dan points out for PC users that the "curve" in transfer function on the
Mac is the same as if you go to "curves." It never occurred to me that it
wasn't !!! (heh heh heh !) I simply think of transfer function as an
efficient way of applying a new curve -- or for that matter an old one --
and saving it for future loading.
Of course, for all I know, someone could be using Photoshop 4, 5, or 6 --
maybe even 3 (????). My impression of version 7, for what it's worth, is
that it's actually a better program than 4 (so VERY rare in upgrades) but
the documentation stinks. That is, the big book that came with is all
about html, & the online info is elusive . I bought a 3rd party book, but
my daughter borrowed it almost immediately and I haven't gotten around to
getting it back.
cheers,
Judy
