I read about people blending several bracketed images taken in quick succession to create visually enhanced images. This gave me the idea of taking long exposure photos and making that into a movie.

Unfortunately, I am limited by the hardware I have. I am testing blending photos to simulate long exposures. There is a lot of software available that will blend two images. Nothing I can find will blend N images. I had to write something myself, but it went quickly.

Oddly, when I started this, getting the camera to wait between photos was the problem. Now I think I need more frequency.

So far I am ambivalent about the results. Like a lot of things, the source material has to be appropriate. Which really means that if I can’t get the proper frequency this technique won’t work.

Though the sample images here look pretty good.

It’s fascinating to watch the way this first image washes out as sequential images are added in.

Two image blend

Three image blend

Eight image blend

The more change there is in an area, the more ghostlike its appearance. (See how the water is getting fuzzed — especially look at the difference from the first image to the last.)

Fourteen image blend

I notice the image seems to lighten (brighten) over time. I wonder if I have a bug in my code? I guess I should look a the source images too.
