-Applied a style I have for HDR preparation, basically removing the default sharpening and adding Base Curve, Highlight Reconstruction and Lens Correction.
-Denoise (bilateral) with radius 18, red and blue channels at max and green at default. This got rid of most of the noise.
-Copied this across all images.
-Exported all to Enfuse with the ‘pseudo hdr or dff image’ plugin as 16 bit tif.
-On the resulting tif: adjust white balance, Tone Curve for added contrast and Color Contrast for added saturation. Color Zones to boost the reds and blues a bit and Color Correction to reduce a blue cast in the blacks. Crop and Rotate to make the image level.
-Then I had some extra noise reduction in Neat Image (might be considered cheating since it is not open source software?).
-final sharpening in Darktable.

I definitely made the colours and noise excessive enough to hurt your eyes and to express my feelings on the subject of oppression and obtuseness of the architecture. Also, my take is a little reminiscent of tourists using flash when they aren’t supposed to.
I’d say that is quite the adventure that you had there!
I took the opportunity to test a new dynamic range compression module that I am adding into PhotoFlow (similar to the tone mapping module in Darktable). Here is what I have been able to obtain so far:
opened all images in HDRMerge and saved the result as a 32f DNG
loaded the HDR DNG in PhotoFlow
applied chromatic aberrations correction and blend HL reconstruction
increased exposure by 2EV
applied the new dynamic range compression module, followed by a filmic tone mapping curve (to compress the highlights) and an additional S-shaped curve
rotation to straighten the framing
The processing is a bit “over the top” for my personal taste, but shows the potential of the algorithm. I will add the corresponding PFI file as soon as the new code will be committed to GitHub.
@Carmelo_DrRaw Adding this new tool is great for hdr addicts like me.
As for the result, can you reveal more details from that coloured glass on top (sorry, I forgot the word in Portuguese…)? I think it is a good test for your new tool.
With enfuse, I could get some details, by masking the more exposed frames before fusing.
As a gimp/nufraw/g’mic user, here is my KISS version (only the central exposure and the lightest and darkest, fed into my ‘Three Exposures’ plugin.
For each exposure, create 16-bit file in nufraw but do not use the denoising feature there (on some of my pics, it helps, but here it only softened them). Instead use gimp’s noise reduction with the default setting of 4 on each.
Open the “correct” exposure, use my plugin to merge the other two.
Add g’mic’s Local Contrast Enhancement.
Sharpen with gimp’s GEGL unsharp mask at the default settings.
Scale from 4036 pix wide to 2018, convert to 8-bit precision, save as jpeg.
This is the second attempt, on the first I went severely over the top with contrast - lovely shiny gilding but of course a loss of detail around the seats.
Maybe what I want to do is produce postcard-style gaudy prints. My own photos are usually taken pointing slightly down, and often a bit angled, and with very visible barrel distortion at wider settings - and I try to fix that up.
So here I’ve added negative lens distortion, rotated a couple of degrees, then used the perspective tool to try to get the side verticals acceptable (all in gimp). Cropped to approx 5:4. Then I’ve used the old Advanced Tone Mapping script, some more contrast, and g’mic octave sharpening. This was just a quick hack, starting from the previous xcf file (which was already sharpened).
I expect everybody here is going to hate me for doing this, but at least the colours are now more likely to hurt your eyes
All pp3 are equal except for the darker image which has been darkened of 1/3 stop to recover highlights.
In gimp I’ve merged the enfuse and mean images and further worked them after frequency separation
Thanks @gadolf for the showing and sharing the humble entrance of the jesuit’s hut, like it that is crooked, lord have mercy and golden showers each of the words, baby jesus flying like a ketamin butterfly … here here a humble servant. A lot of interesting approaches from everyone =)
Personally wanted to try the penguin’s new dress and so secondly went with single raw and some unorthodentist approach (changed from standard to raw color)… but boy @Carmelo_DrRaw this last iteration of PhF is unstable… fast, yes, breathtakingly so, but very hungry ghost driven, brace yourself when editing jeje. Anyway I cowardly jumped the boat here
Then firstly I hdrmerged the motherphotons whith such bad taste that a trail of phosphorescents ants followed me all the way to hell. Then so to synth hdrmerge >> PhF (behaving under the influence {of speed} cortex nimb) >> woodoo g’mic and a LUT… 'cause the acronyms helps evacuate. It looks a bit like aggrigio’s but I swear I stole it myself. Wel enough BS, a good nite 4all
Ah! This thread wouldn’t be complete without @chroma_ghost’s invaluable metaphors and edits!
Now it is.
Well, almost.
Movie recommendation still missing.,
Could you try to reproduce the instabilities? I have just prepared a new version that fixes few small bugs, but recently I could not really crash the application with the new tool…
