RE: [APML] Revisit of M16/M17

["Jeff Ball" <jeffball@zoominternet.net>]

Thanks so much for the tips, Jerry.  I do use a 5000k light box.  I find
it hard to get the back illuminated look from the slide to show up on
the processed image.  The only thing I do with the scan is make sure the
histogram is in good shape.  Maybe I should tweak the curves in the
scanning software.  I will definitely try the zoom box on the Nikon.
Thanks!

Hi Jeff,

Excellent results.  It looks really good to me.

If you are going to try to match the view of the original slide make
sure 
you use a 5,000k light box.  This probably wouldn't work too good if you

shot the original under any light pollution though. <G>  


I don't have the Nikon scanner hooked up right now, but I'm pretty sure
all 
you have to do is draw a crop box, and hit the plus magnifier icon.   I 
seem to remember that you might have to run the preview again to get a
high 
res display of the crop to show up in the preview window. Then you have
to 
remove the crop and run preview again to get the 1:1 sized preview 
back.  It's definitely worth using the magnification function when you
are 
setting the "sky background aim point". I've started using that term 
instead of "black point" because you don't really want it black at
0,0,0.
