Description

the newly implemented exposure fusion has very little available settings. It would be nice to have settings for:
1) the number of exposures (not only two or three)
2) scalar weights for the three quality measured described in the paper (contrast, saturation, and well-exposedness)
3) an additional quality measure for regularization, something like the 1/exp(|median(Image Stack at Pixel(i,j)) - (Pixel(i,j) at exposure k)|) with an additional scalar weight (see 2). I think enfuse has something like that

the paper mentioned that they specifically used the multi-resolution blending with Laplacian pyramid to avoid artifacts like halos. I am not exactly sure how the 'shadow and highlights' module works, but I guess at some point it blends the adjusted highlights, the adjusted shadows and everything else back together to one image. Would it be possible to use the same multi-resolution blending in 'shadow and highlight' to avoid its prominent halo effects?

Work on something like that (better shadows&highlights) is already done in https://github.com/darktable-org/darktable/tree/monochrome – don't get confused by the branch name. :-)

that's great! Will it be part of the 2.2.0 release? As far as I remember the change log of 2.2.0rc1 didn't mention it
