I thought it might be interesting to see the effect of sharpening this small image - so here are some comparisons

Here is the original image

This is Dan Margulis standard PostCard sharpening action which I feel improves the image, although it sharpens the middle distance which may not be a good idea.   

Just one pixel of the Local Auto-Levels action which is a subtle improvement everywhere.  

And a whopping 13 pixels of Local Auto-Levels, which burns out the bodies, but adds quite a lot of contrast to the background - and is definitely not the way to go!  


So lastly - what about the colouring?
