Very clever idea. Can't wait to try this!

Thanks. Let me know if you have any feature requests.

How about making it output video, with a rolling average over the previous N frames. Then you can experiment with having the brightness of a pixel impact how many frames are affected. For example, make brighter pixels have a longer impact to get light streaks, or have darker pixels last longer for a kind of hdr effect.

And what's the point of that? Videos are generally low resolution, compared to photos. We're talking order of magnitude difference - 2 megapixels vs 36 megapixels.

I originally wrote this for a computer vision application (averaging frames attenuates low-light noise) but I'm curious what other use cases people come up with. :)

You can also do the same with multiple stills and retain full resolution, which may be easier to work into a regular photo workflow. Take a dozen shots at ISO 9000000 and pipe into enblend -> crystal clear result.

Good idea. I'll add support for still images.

Cool, now do image stabilization so it works with handheld video.
