Like many people here, I'm particularly interested in astro timelapses and 'holy grail' timelapses.
I've tried to do several 'holy grail' timelapses (day to night or night to day), but I haven't been able to get it quite right. I've also tried using qDSLRdashboard with my Nikon Z6 but have found it quite buggy and it often crashes, even though I have it connected with USB to my camera.
I heard from Timestorm Films that he uses a Sony A7RII and A7RIII to do his 'holy grail' timelapses, and then smoothes the exposures and deflickers in LRTimelapse.
He said the way he does this is by using a setting on the Sony A7 cameras called "autoISO minSS" that when used with Aperture Priority mode allows for a 'holy grail' timelapse. The maximum shutter time is set (i.e. 20 or 30 seconds) and the maximum ISO the camera is permitted to use is also set. During sunset, as the light darkens, the camera ramps the shutter speed to the maximum value, then ramps the ISO setting. The reverse is true during a sunrise. Here is a video on youtube that explains it: https://www.youtube.com/watch?v=ONggTOYtHdk
Has anyone else tried this method for a 'holy grail' timelapse? If so, what was the result?
I am aware of the reasons against shooting with auto metering in Aperture Priority mode posted by Gunther here: https://forum.lrtimelapse.com/Thread-why...-a-av-mode.
However, I have also seen Martin Heck achieve some really incredible outcomes using the method above:

Could anyone do me a favour (if you live outside the city) and try to auto expose a single shot with the method above to see if you can get the Milky Way with this "autoISO minss" method?
