Re: Intervalometer for A6400 +30s exposure

Just stack 30 sec exposures.

With CMOS image sensors there is little difference between stacking 30 sec, 1 min, 2 min and 4 min subs.

In my tests (some light pollution) 1 min sub exposures is the sweet spot. Do hardly see any difference whrn stacking lots of 30 sec exposures - so that it is in my case.

Longer sub exposures is a relic from tge days of photographic film (reciprocity) and CCD cameras (much higher read noise than CMOS image sensors).

Shorter sub exposures than about 8 - 15 sec is byond the soft spot.

Just try for yourself.
