High dynamic range shooting and editing

After further close study of Boris Hajdukovic’s YouTube episode 56 (explaining the channel Mixer) and 57 (processing high dynamic range raw files), I revisited this image of the river Derwent in Borrowdale, English Lake district. It was late evening and the light was reducing rapidly but I was attracted by the colourful sky. I carefully set the exposure so that the sky was just short of highlight clipping but that meant the remainder looked very underexposed.
I used two instances of tone equaliser to balance luminosity and increase contrast. I set WB with colour calibration then removed some red from the sky with channel mixer. I used two instances of Colour balance RGB one of them to liven up the green using a mask. Finished off with an instance of diffuse and sharpen for local contrast and a 2nd for sharpening.
2nd image is unedited.

I only see one image, and at full size it is very much not sharp. Everything has that slightly-out-of-focus look. But it does have a fancy frame, so I assume it’s the edited version. Nice photo with good composition otherwise :wink:

Thank you for your comments. I realised the lack of sharpness after editing. I think it might be due to slow shutter speed. I tried to upload the 2nd image but I don’t know why it’s not worked.

Here are my suggestions. I’ve opted for a softer mood in color and a harsher one in black and white.

Greetings from Brussels,


To my eyes its definitely not motion blur - not at all streaky. Maybe an AF hiccup? Very nice view through! I tried editing but my version didn’t really add much… I like yours.

Thank you. Both are an improvement. Love the monochrome.


I just had a quick play with the image and I feel there is a lot of potential to develop this image. I used the DS module and lens deblur preset hard to help with the softness.

I agree, @Terry. Here is my attempt, experimenting with extreme settings in the filmic module:

Thank you for your interpretation. Is this done in darktable?

Yes with darktable 4.4.1 :slightly_smiling_face:

Very calm, a little like a painting. I tried to enhance this feeling.
