We're going to Iceland and shooting some long exposure pictures at night. Between us, we have an LX5 (max shutter speed around 4 minutes), ZS7 (60 sec) and ZS20 (15 sec). It seems that there is no way to turn off the long exposure noise reduction on these cameras, effectively halving the number of pictures that we can take, which is particularly annoying when you're trying to shoot the aurora, which can be transitory.
I've read of people manually turning their cameras off during the dark frame period, and subequently using a spearate dark frame "picture" in PS to remove the noise.
Before I tried that, I wanted to ask if anyone has done this on this forum, and what their experience was--the last thing I want to do is to brick the camera. Or if they have any other suggestions, short of buying another camera!
TIA.
