Also you could include a short sample video that has a movement of light, midrange and dark shapes on light, midrange, and dark backgrounds.
That could be used to produce previews of settings and presets: and allow controlled tweaking of those presets.
After a bit more thinking, you can't really make an HDR from a series of regular shots, because the low dynamic range shots will be missing data in the low range and/or high range. You'll still be mixing with blown out data.
HDRs are made from multiple bracketed exposures. A slow exposure getting detail and color data in the shadows, a fast exposure getting detail in the highlights, so nothing is blown out...
And If there is movement, there's artifacts. The HDR feature in iOS shoots fast, but large movements fail.
So I'm liking the "lighten only" and "darken only" blend modes more.
(I can't imagine other blend modes working great yet, but probably worth looking into.)
Right, a time stamp. This would be cool, but would like a at least a couple size options, so I can hide it small in a corner. I don't like destructive editing so I'd rather it saved to a log. (Also with the other current settings for that frame in a .csv file. Then I can add those later if I want.)
I have a kind of similar suggestion: "More blending modes, like lighten for light trails/streaking lights."
The current blending is like "normal" or "mix". HDR may be possible and good too, but I think a "lighten only" blend mode would as fast (or nearly) to process than the current blending.
Glad this is planned!
