Hi guys! this seems to be a lovely place to arrange the discussion.
Since there’s not much on the web about fused HDR processing with Darktable, we might have it comprehensively discussed here )
So I have an image which I got by fusing three shots of a landscape at different exposure (-1, 0, +1). For that I used DT’s HDR function which provides fusion of RAW files (unlike the conventional HDR masks blending or .tiff output fusion). I’m pretty happy with the dynamic range I got after that. Then, after adjusting the exposure and white-balance controls, I have obtained acceptable average lightness and colors. I believe, those are basic steps to be done for the HDR to average lightness and whitebalance of the fused images.
Then I’m completely lost with my following step.
Once all of the above was done, I started tweaking the tonal group to bring out the contrast, since, after the fusion, the image lacks contrast and has washed-out look. Though, nothing helped. Each tool could not provide any acceptable result - it increased the contrast while lost a lot of original colors. For each tool I referenced the manual, but with no significant success. Also I could not find specific advice for HDR development. The Tone Mapping provided the best contrast, but, unfortunately, it sacrificed a lot of colors initially present in the HDR. The image came out contrasty, but dropped a lot of saturation and looked grey-ish.
It looks there is a large potential in this image with its high dynamic range, but I can’t get it further processed correctly. Did anyone experience the same problems with the contrast?
Here’s what I got after basic processing steps http://i.imgur.com/vwhW9S0.png
Any advice how to get rid of that greyish look while retaining the colors?
