Recently on vacation we visited a dripstone cave in Syrau, Germany. Apparently someone thought a cave in itself wasn’t exciting enough and it should have a L.A.S.E.R. show at the end of the tour. It was both jarring and impressive.
An opportunity for me to do the ‘wrong’ thing, because Darktable allows me.
btw I couldn’t get the centre of the lights, and the diffuse patch above them, smooth at the same time with highlight reconstruction.
I suspect some type of read-line oversaturation. But I do not know much about the protection circuitry in CMOS imaging sensors. These horizontal lines reminds me of many linear defects that I ran across in my semiconductor days.
