I took this shot back in 2016. K-3 + FA*300mm f4.5. The light was very poor - well into twilight. Even at 1/50th sec, f5 and 6400 ISO it was still heavily underexposed (1.5 or 2 stops or so). So really more like 18000 ISO plus. Which is very high for the K-3. I shot RAW + jpg; here is the SOOC jpg:
I have recently reprocessed the RAW file with DxO's PL5 and its DeepPrime noise reduction, which uses AI. I pushed the DeepPrime slider a long way. It did very well, without obvious artifacts and with minimal loss of detail. Finished it in Nik Color Efex.
Still suffers from the slow shutter but pretty amazing outcome in the circumstances. We are seeing some game-changing improvements in NR software lately.
