Review: Canon EOS R3 by The Digital Picture | Canon Rumors


I believe the idea is a single RAW file with the MSNR applied, i.e the multiple shots combined into a single RAW file with lower noise. There are dedicated astrophotography postprocessing apps that do that sort of thing (not on RAW files, though), but I’m not aware of any standard RAW converters that allow combining RAW images to reduce noise. The concept is similar to long exposure NR, where the camera takes a dark frame after the shot and subtracts it from the primary image before writing the RAW file.

Note that there are a couple of workarounds to achieve the same ends. The way to get a RAW file is to use Canon’s multiple exposure feature and set the exposure control method to Average – that lets you take up to 9 exposures to combine (which would give better NR than the 4 exposures of MSNR). Another is to simply take multiple, successive exposures and combine them in Photoshop (overlay them and adjust the opacity to equally weight them (i.e. opacity = 100/image number, so the bottom image is 100% opacity, the second is 50% opacity, the 3rd is 33%, 4th is 25%, etc.).
