As the weather has been lousy and Harry's been feeling poorly, I've been spending some time with older images where I took multiple photographs of the same thing. In this case, I was trying to get an interesting surf around the rocks on the so-called beach outside the White Point Resort near Liverpool, Nova Scotia. (Seeing the rocks, it is no wonder so many Canadians come to southern New Jersey beaches every summer.) I never did anything then with the seven source photographs as the surf wasn't all that interesting. Obviously, digital processing allows many different techniques than would have been possible in a wet darkroom in 1978.
The two images represent different processing techniques. In #1, the base layer is at 100% opacity and the other six are at 20%. In #2, they were all at 100% and I then used Photoshop's Auto-blend feature. In #1, the wave action would have smoothed out completely had there been many more source images, but you can see some of that beginning here. In #2, which appears sharper and more grainy, you can see more aggressive wave action. Considering how similar the combined images are (the yellow source-image borders are the same in both) I was surprised that the Context-aware fill around the edges looks so different.
#3 is the same beach clipped from a live-view webcam this afternoon. It looks like they hauled some New Jersey sand to this Nova Scotia beach. Or maybe the tide went out.
I've been doing the same, Andrew - revisiting old photos for editing. This post is an interesting read, and I enjoyed it. The beaches are lovely. I love the New England/Canada coastline.
