Sunset scene with darktable & rawtherapee

It works seamlessly: HDR windows display highlights brighter than white in the rest of the UI. If I turn off the highlight rolloff and save the file as an EXR image, then the sunset looks amazing if you open the EXR in Preview.app (also the train has bright red lights on it!).

wait…WHAT?!
this works? not only for HDR videos, but *.EXR files as well? OMFG!

@paulmiller *.exr and screenshots, or it didn’t happen!

[paulmiller]

Screenshots of HDR windows are tricky: firstly, command-shift-3 doesn’t work (it captures the screen to an 8 bit buffer and clips the >100% bits leaving ugly colour casts), secondly - how would you view it?
Here is a literal screenshot, I adjusted exposure so the highlights don’t clip. Exr is on the left, JPEG on the right.

The actual screen looks more impressive because it is much brighter.

Here is the .exr:

I do image white balancing in CAT16 space - this is the profile for that (zipped because I can’t upload .icc files (get a message about corrupted image files?).
CAT16_n.icc.zip (737 Bytes)

You can get a similar effect by turning the display backlight up to full brightness, underexposing the image by a couple of stops and viewing it full screen (becuase otherwise any UI white is really bright) - but this is much more fun.

@paulmiller The screenshot is helpful. I can see more contrast and detail in the EXR.

I have been hesitant to tackle this one, but I finally decided to try on it.

You missed the tip of a branch.

Hope I did not ever did it, tryed to mimic the highlight processing set in the example and did it to my taste after that, nice pic !

Shameless haloing. I kind of like that.

Hi @PebalX, welcome to our forum! We focus on free and open source software for photographers. I hadn’t heard of SNS-HDR pro before. Is it FOSS?

We really try and keep proprietary software out of our PlayRaws, since it is not easily obtainable by all members of our forum.

It was mentioned on the forum a few times before. Looking at their website, they have are closed source and licensed as commercial freeware, non commercial or commercial products.

For me, it looks like, that zbyma72age and pebalx are trying to do some commercial for that hdr-software…

[afre (Alan)]

Zbyma72age does use GIMP though. His workflow is explained here (I haven’t followed his link yet.): Snowy Waterfall at Noon - #22 by Zbyma72age.
