Re: [APML] Beginner scanner images

Thanks Jerry and Herm!

Jerry, I had your CD open all thru my processing attempts last night---without
it I would be totally clueless. Thanks a million for putting it out--the PS
textbook I purchased is nowhere in the same league!! 

The histograms for the prescan were odd. I am not using Auto exposure 
adjustment on the scans. I found that by increasing the exposure I could 
fill the RGB histograms from edge to edge as opposed to having a tiny 
curve in the middle of each channel.Too much exposure, and the edges 
get clipped.  As the exposure was increased, the vignetting I assume is
associated with the petzval design of the TV101 became increasingly
apparent.

The shapes of the curves are sure different from the examples in your CD
and from the results I got when scanning a slide! I'll try a round with the
tiny
curves in the middle of the histograms.

I had the misimpression it was best to try to accomplish as much tweaking
as possible in the original scan.  So far each Auto feature I've disabled
seems
to have yielded better results! Still its more likely operator error than any 
deficiency on the part of the hardware/software!

The vignetting is something I've become more and more aware of in my shots.
I really didn't want to tackle radial gradients, but guess thats going to have
to be  
a standard tool in my toolbox so long as I stick with the TV101. Do you
suppose
its possible to develop a "standard radial gradient mask" for my TV101, and 
not have to make a new one each time?

Thanks again for the pointers guys--I'll post results as I stumble along the 
learning curve!

Take care--Steve
