This is from my first Sigma 105mm F2.8 session on a 2nd hand Pentax K-50 that slowly developed the common aperture block. I didn’t realize that and ended up shooting most of the session too slow and too noisy.
Do you know how Upscayl works? I can’t parse these docs yet - Guide · upscayl/upscayl Wiki · GitHub - it’s definitely using the Nvidia GPU and didn’t ask for pytorch at launch like Cupscale.
Philip mentioned somewhere that he chose Gigapixel in the end to skip geeking totally out on all parameters known to man and machine
Darktable came first. Maybe I should have skipped the filtering, just export after basic development, then use chaiNNer, and then process further.
Here it is: only filmic etc. in darktable, then chaiNNer, then darktable with diffuse or sharpen with the local contrast preset + the local contrast module with default settings.
It’d probably be good to mask the results and/or experiment with models, as there are weird artefacts, such as:
Or how the hair is only sharpened inside a block:
@dqpcoxeas@age thanks! Very curious to dig through your sidecar and learn new DT tricks
I remain tempted to try and isolate her, remove the pole behind her right hand and the concrete chunk of a building as well. Blue shirt guy breaks the dress code and is out of there soon.
Didn’t antipate that at all before this round, thanks for the inspiration.
@kofa I’ll leave the tech notes for now and another thread, your feedback and example edit is much appreciated
AI codeformer robots revealed a definite Pentax fixation. Not sure if there’s space for two portraits within this busy frame and Jubilant Stretch doesn’t need that much sharpness to stay happy. Mono seems to balance her joy better.
Love it! Are you working on kofa’s jpg to achieve such face sharpness?
It’s now becoming obvious that the grey-blue-ish buildings I caught them in front of is a major part of the color clash and challenge. Yours and @age 's seems to mix up best on my display.
Maybe the Sigma 105 met a soft limit at this scene or K-50 is damaged. I ran some quick DT styles to for reference.
