Hey folks, could anyone help me with darktable modules on how to improve a picture?
It’s a pretty high ISO level and a big crop, but I can’t make it decent.
You can load my .xmp file to see the adjustments, but it’s basically standard profiled denoise, and two instances of diffuse and sharpen. One factory preset and customized acting more on local contrast. Apart from that, just a bit of contrast in sigmoid and a tweak to white balance in color calibration.
There are some open source AI tools like upscayle and Chainner - I’m not sure whether they could help with this.
Whenever I have a tight crop or high ISO image, I use one instance of denoise (profiled; wavelets), and try to just embrace the noise and blend it with grain effects, color balance RGB (with fine tunes to exposure in the brilliance panel), and other tone curve oriented filmic edits (to boost midtones), all capped off with sigmoid compression/ fine tuning at the end of the pipe.
I’ll attach my XMP file… which I’m afraid to say might look a bit of a mess, but it’s my current filmic workflow. The tone curve modules are meant to boost the midtones (I target a sweet spot around 70IRE), which I find key to making an image look more filmic.
Took a bit of elbow grease, but I added some chromatic aberration masks to try to take out all the chroma noise near high-contrast transitions (wasn’t entirely successful, but better than where it started).
Quick edits…not really better than yours… used the lut from the recent loglin post in the first pair …they are relative and perceptual renders… last two with filmic DSC02458.ARW.xmp (28.7 KB) DSC02458_01.ARW.xmp (17.8 KB)
your balancing of noise reduction to detail preservation is excellent, second to none in the thread by a long way for mine, but the image is let down a bit by the blue treatment bleeding into the wingtips.
As I said in a previous thread I always let the luma noise almost untouched to avoid a flat-plastic like rendering. When printing this is not even visible and it keeps crispy details.
Another denoise challenge…
That’s what I could achieve. I second that too much noise reduction leads to a plastc look. So the goal is to keep the noise even and controlled.
Your edit here is a png file which seems strange. Is this just a screen capture of darktable ?
What kind of modules did you applied in the darkroom view ?
Could you share your XMP file ?
@foto the context included in your crop is better than the tight crop on the bird alone. The picture is now telling me a story about a single bird from a flock of birds.
Here is my attempt. I chose a very different crop. I also did selective sharpening on the bird and extra denoising of the background. There are white spots in the image, which are not fixed by the hot pixels module. I would feel compelled to use the retouch module or GIMP to remove these distractions even if they where really in the original scene. But I have not done that here because of the effort it would take.
