Re: [APML] Photoshop conversion to jpeg

[Alan Voetsch <alanv12952@yahoo.com>]

Hey Bert,

I'm pretty much done with them, at least what little I can do to them.
I spent many hours last week working with levels, curves, etc... after
re-scanning some older negs. First time scanning since I've had the
newer computer (March '03), which is the reason I got this computer in
the first place. 

The negs have been in 16 bit mode all the time.
I wouldn't know about normal looking histograms, some of mine end up
looking pretty strange. 8-)

The other thing I was wondering about is; after converting to 8 bit,
will the 'save' dialog box offer me the option of saving as a jpeg? Or,
will I need to look somewhere else?

For those wondering, these were the very first images I've processed in
18 months, hence the elementary questions. And let's face it, I've
never claimed to be a Jerry Lodriguss anyway! 8-)

Thanks Bert,
Alan
