Captured on my Sony A7 II attached to a Sigma 20mm f/1.4 DG HSM Art wide open for 10 seconds at ISO 6400.
Not a particularly heroic shot to get – save for waking up at 4 AM to drive up the Volcano – but quite pleased with the result.
Processing was done entirely in Lightroom with quite a few sky detection-, luminance-, and color masks as well as a minor Lightroom AI denoise treatment.
