Although you can use the haze removal module of the darktable, I usually find out that I prefer to remove haze manually using tone curves with drawn masks. The following photo has been developed by such a technique.
Hi. I’m trying to use your xmp but Darktable tells me about wrong version of bilat filter (?), and the image results very dark. I’m running Darktable 2.2.5 on Arch Linux. Besides, I have no haze removal moduel, maybe it’s found in the latest git version?
By the way, thanks to everybody, now I have to learn something from your examples:)
I tried the RGB curves with the GIMP and I was able to get faster to a useful point, so it looks like it’s a feature Darktable is currently missing. I read a bug report about it.
I don’t know about the license of the raw, let’s say that you can use it but report me as original author, in the remote possibility you would use the image somewhere else:)
@Dario Here is a guide to licensing: PlayRaw stuff to keep in mind. You can apply it to anything you create, not limited to PlayRaws. Just a common way to communicate how to respect each another’s work.
@Dario Which GIMP are you using? If you haven’t already installed 2.9.x, I suggest you try it. It has features that are essential for the type of edits you would need for this raw.
@Dario I’m just curious…what version of the image most closely matches what your eyes saw the day you took the photo? Your original? Your edit? Someone else’s edit?
Well, actually the mountain range was quite blueish, I have to say that the raw from the camera reflects more or less faithfully what I saw that morning… Probably James’ version is the most faithful representation of what my brain did perceive. I estimate the mountains were about 20km from where I stood.
I’m using an Appimage of Gimp 2.9.5 from last year downloaded from this site - newer ones don’t run on my computer.
I am glad that I wasn’t too far off. I tend to exercise restraint when processing raws, so you could be more aggressive with the steps and arrive at your desired outcome. And examine @james’s pp3, although it seems like you prefer dt.
That is an okay version. If you have any trouble with the appimage, I am sure that @Carmelo_DrRaw would be happy to assist you.
Your photo is an excellent test for dehaze methods, thanks @Dario. Here I used RawTherapee 5.3-dev tone mapping, plus the new® so-called HDR tone mapping (which is based on the Fattal code from LuminanceHDR), and Retinex to help beat the fog, and adjusted some color curves.

Equalizing is a powerful tool to help us see what an image contains, like a “proof print” from a negative. It may give a lousy image aesthetically, but this one is good.
