My 12x20 images at 1500 DPI amounts to 18,000 x 30,000 pixels, scanned at 16-bit and in color. Once processed down to greyscale they are manageable. I generally have no need for such crazy-high resolutions though
but it's fun.
The following link is to a MacRumors Forum post this morning from someone who makes timelapse video of the night sky consisting of 2,800 to 3,500 images: https://forums.macrumors.com/threads...ctive.2350883/
He says that his Mac Studio Ultra has cut his processing time to 1½ hours:
"So in a period of 3 years I went from unstable Photoshop processing that took 10 to 12 hours or more to the Mac Studio M1 Ultra that is capable of processing my images in 1½ hours time with no computer crashes whatsoever... One day the computer will be so efficient that it will only take a couple of minutes to process this many images but I am very happy with the progress thus far".
More:
"I typically use 10 to 13 second shutter speed settings depending on the moon phase and target goal for the night with 3 second intervals between each image and allow the camera to run from darkness setting in to the next morning first light. The number of night sky images can range from around 2,800 to 3,500 during one overnight session depending on the time of year and the duration of darkness at the time. So, I have lots of images that I have to transfer from a camera SSD chip to my computer and then into Photoshop so I can adjust, stack and render into video to produce a time lapse video of one night imaging session".
"The number of images that I have been processing at this middle of Summer time of year is around 2,850 so I know that Winter time processing may bump the processing time up to around 2 hours or a little longer than that due to the higher number of images during the night. Computer crashes are history for me".
