Re: [APML] More shots (M101, Leo Quad, and NGC 2174, AKA "MonkeyHead" Nebula

Alen,

Your shots are nice but I think they have a lot more potential. I 
downloaded your images to cheek the histogram and all the data is 
crunched up to the left hand side. It also looks like some of the 
fainter data has been clipped and therefore lost for good.  If the 
histogram after scanning shows all the data compressed in a narrow band 
or blocked up against the left side then you might want to use the 
curves and tonal tools in your scanning software to get an initial 
stretch on the data before processing further in PS7.
