A few months ago I experimented with Imagemagick by using it to merge very similar photos of flowing water to give the impression of a longer exposure.
Here are a few more examples.
By merging a series of thirty photos taken two seconds apart I created a pleasing image that looks like a sixty second exposure. The day I took these photo was overcast and dull, but not dark enough to do an actual long exposure like that without the help of some fairly dark filters. I used the intervalometer in Magic Lantern to shoot this so I didn’t even need a remote release. My camera did all the work! This was created using the following Imagemagick command line:
convert *.jpg -average average.jpg
I combined 60 long exposure shots of the night sky in the mountains of Utah (during the Automattic Grand Meetup a few weeks ago) to create a single long exposure of the stars moving through the sky. Thanks mkaz for publishing this post on interval shooting where I got this command line:
convert *.jpg -evaluate-sequence max combined.jpg
Finally, another series of sixty shots taken in Utah. The same convert command line was used to process these.
In the image above I should have cloned out the wires in the bottom left of the image. Lightroom makes it easy to make the same modifications to every image. Work on one image, then select all the ones you need and click “Sync Settings”.
It can be frustrating taking these types of photos as your camera is shooting a long series of very ordinary shots, and the final result can’t be seen until the images are processed correctly but it’s certainly worth it.
Update on December 1st: here’s one that didn’t work out so well. It was so windy the camera shook the whole time.
