Wow, glad I watched that video, I didn’t notice the auto match tone curve in the UI.

I’ve been compiling latest dev branch for ages, I really need to pay more attention to things I think.

@agriggio power, applying math like a .

Some curves, a lot of saturation and white balance

Here is my take. Required lots of tuning and patience. Doing this from a sad screen so I don’t know how good or bad it looks. In my estimation, it is average looking compared to the other attempts. However, I hope it recovered enough of the sky and greenery to satisfy @isagalaev.

PhotoFlow
a) Linear Rec.2020 with negative clipping.
gmic
a) Curve to remove linearity.
b) Subdue details (guided smoothing) in prep for #3.
CLAHE (wish gmic had it).
gmic cont.
a) Expose shadows (luminosity mask).
b) Curve to increase contrast + brighten shadows, stretch chroma, recover details (guided sharpening).
c) Prep for sharing (contrast, resize, fp to jpg).

Enjoy!

[Edit: uploaded wrong version. This one is slightly sharper.]

some quick RT basics, gmic popshadows + simplelocalcontrast, color-efex vignette + warm-up curve

thx for this nice play raw

Here is my first take with PhotoFlow. @isagalaev - thanks for sharing this image, it’s an excellent example for testing the various shadow adjustment methods!

My edit is mostly based on exposure compensation + ad-hoc masks, plus some fine tuning with RGB curves:

Hi Morgan,

I have downloaded your .PP3 file and tried to apply it to the RAF file of this playraw, to see how you achieved your excellent result in practice. However, after opening the RAF file in RT and applying your PP3 file with the “Load a profile from file”, this is how the processed image looks like:

Here is the information about my RT version, running under OSX:

Version: 5.3

Any idea why the output looks so different with respect to your edit?

Thanks!

The version @Morgan_Hardwood used has some new tools. For example:

[FattalToneMapping]
Enabled=true

Carmelo_DrRaw · February 5, 2018, 6:28pm

Thanks Ingo! Is there a place where one can download bleeding-edge OSX builds? If not, would there be some interest in such a possibility?

@Carmelo_DrRaw

Carmelo_DrRaw · February 5, 2018, 6:36pm

Stupid me! I completely forgot about that thread… thanks!

Morgan_Hardwood · February 5, 2018, 6:58pm

Also, if the image still doesn’t match, you might want to checkout a commit from dev from the day I posted that image, as Fattal’s behavior changed over time and I’m not sure whether its behavior from the day I posted hadn’t changed till today. Backwards compatibility is absolutely not supported for development builds, but we do try to support it for stable releases.

afre · February 5, 2018, 7:46pm

What are those?

Cool. Is that an application of a certain paper? I know Fattal has a bunch of stuff on tone mapping.

But it was changed by many people before it fell into our hands.

4 posts were split to a new topic: Processing another very high dynamic range raw

darix · February 6, 2018, 8:40am

I did not want to move this as his post touches both the current and his own image. that’s why i asked @Gobo to start a new thread.

Gobo · February 6, 2018, 8:57am

Specifically for darktable. Mask features in darktable is what I would love to use and what I am missing in LR. I was thinking about GIMP when I saw tutorials with masks in dt so I decided to give it a try.
