Show HN: Simulate long-exposure photography with video
- blt 13y agoCool, now do image stabilization so it works with handheld video.
- tmchow 13y agoVery clever idea. Can't wait to try this!
- eliteraspberrie 13y agoThanks. Let me know if you have any feature requests.
- cookingrobot 13y agoHow 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.
- ye 13y agoAnd 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.
- eliteraspberrie 13y agoI 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. :)
- tedunangst 13y agoYou 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.
- eliteraspberrie 13y agoGood idea. I'll add support for still images.
