Hello Antonis,

Your  "histo-wrecking" comment makes me wonder if it is not 
better to back up and do things in the color channels before I 
convert to greyscale.   I recently tried to make "improvements" in 
the Tone Curves of my scanner prescans, but only managed to 
change my beautifully smooth r, g's and bees into  storm 
wreckage. :-(  This learning curve gets steeper by the day.  :-)

I think the secret is to "just do it" until I get a feel for what works. 
My only fear is that I will lose a lot of info in the process.  Those 
wrecked histograms don't necessarily show in the monitor 
image, but I can imagine that a large print  will bring any 
weaknesses into view.

    Happy Holiday!
