There is certainly a Photoshop look as here in this shot taken tonight and I'm tempted to go back to GIMP!

Especially as I've discovered that in certain B&W shots there is still banding in the feathered brush even in 16bit, the thing I changed to Photoshop to avoid. Also I find the sharpening method I used in GIMP to be superior.... perhaps I'm just in a mood because I couldn't get the shots I wanted from tonight... or I've just over cooked this one... or.. or....
