My editing style is entirely inspired by film. My favorites being Kodak Portra in varying speeds and the Fuji Pro film series. For that reason, I usually stay in the “Negative New” tab in the film emulation presets (thank you again, @patdavid) in G’MIC and various RAW editors where they are available. Custom curves, strength and intensity tailored to each particular image, are a big part of my work flow as are color layers set to a low opacity on soft light or what ever mode suits best.
For the more “artistic” edits, I nearly always stick to GIMP, while RT and DT are used for basic things such as, WB, CA correction, defringing, and exposure compensation where needed. If working in DT, I always apply the Fuji Film base curve to every image despite the fact I shoot with a NIKON D90.
I like this treatment. On another forum, folks have been dredging up old railroad photos of historical significance, and some look a lot like this (well, put a train in place of the lighthouse… )
The second step was to match that image in darktable, first I’ve centered the middle gray at 18% again, the working space was set to PQ bt.2020,then I’ve used rgb curves and the HCL equalizer.
In gimp I’ve added a very small amount of grain and bloom effect in the highlights with a luminosity mask
Lovely photograph!
My attempt in GIMP. I felt that the tree and the foreground should frame the lighthouse.
As to film emulation: a sort of Provia, by adjusting component colours.
