Re: Christopher Creek...How should I crop or otherwise change it
150 pixels on the long edge is a bit small to see clearly, Bernie. When I try to view at full screen size it looks a bit soft, which is probably due to the sizing.
I normally work around 1000 pixels but you can go a fraction larger if you want.
As far as I can see, the basic image looks fine at that crop; unless there are any specific areas that you wish to remove or to zoom in tighter.
Re: Christopher Creek...How should I crop or otherwise change it
As mentioned, it's hard to comment due to the small size. The only thing I can offer is that IMO there is a lot of dead space in the foreground. Unless a larger version reveals underwater details that aren't evident as presented. Maybe try a pano crop removing some from the bottom
