A 51-MINUTE exposure through pre-sunset, sunset, the blue hour and slightly into the black hour.
How:
9mm Ultrawide Laowa lens, Leica SL2, shutter priority (1/2 second), nonstop continuous burst mode (manual cable release - or internal intervalometer) AUTO ISO (ISO creeps up higher as it gets darker, as the camera meters continuously) f/8, getting blasted by waves and using my hat to protect my camera's lens and body from the occasional big one.
Developed by using Lightroom Classic - Develop Tab (Camera Raw), Adobe Adaptive Color profile (which goes a long way in helping equalize the exposures), basic corrections done in a few batches (developed one image and applied all setting to the batch), Sharpening OFF (I NEVER EVER use it - it use pure damage), Color Noise Reduction OFF, Luminance noise reduction OFF, NO "Denoise", "Raw Details" ON (much better demosaicing), Remove Chromatic Aberrations OFF (this softens images), Lens Corrections off.
Then the images were all batch saved as native sized 16bit Tiff's. Then they were all loaded into Photoshop into one layer stack, turned into a "Smart Object" (packaged) and then in Photoshop, Layer/Smart Object/Stack Mode/MEAN (average) was chosen. This perfectly averages all the exposures, producing an image with literally NO NOISE (it gets averaged out) and produces the exact same look as if it was taken as a single exposure (yet with ZERO noise). And you get to choose any exposure length after shooting (by averaging different amounts of images taken) and you have a lot of images to cull through for other incredible single shot moments, and you miss nothing!
My proprietary "Detail Extraction" techniques produced a new pristine native file that was over 800 Megapixels and almost 120 inches tall at 300 ppi, before any sizing or sharpening... was done.
