Hello, I am having problems working with a specific set of NEF files I shot using my Nikon D610 SLR. The other night I shot some photos of Comet Neowise. I planned to use stacking, and shot 9 photos in a series. I can bring most of these images into Affinity Photo and either develop them or create a new stack without a problem. All but this one set of stacked images. This set of photos is unique from the others in that they were all shot at very high ISO (25,600), where all my other NEF images are much lower (3000 or less). I can view these images in the MacOS Finder, in Preview, in GraphicConverter, and in other applications, and they are rendered fine, even in GraphicConverter's RAW processor (which is inferior to Affinity Photo's). But if I try to open one of these RAW files for developing in Affinity Photo, I get a display of random RGB noise. The first few lines of pixels in the image show normal, but the rest is noise. And when I create a stack of these in Affinity Photo, the top band of the image is fine, but the area of random noise is evident, although greatly reduced due to the stack mean. Affinity Photo does report the correct photo data (ISO, camera, lens, etc.). Attached is one of these NEF RAW images, a screenshot of what I see in Affinity Photo when I load one of these images (mostly random noise), and a screenshot showing what MacOS Preview displays for the same file (a bit faint, but fine). I have not altered the files in any way; I've only download them from the camera. Since my other applications can open/display the file, It seems to me this is a problem with how Affinity is handling the files, as if at a certain point in the file it is interpreting the data incorrectly. I think this set of files might generate a decent image of the comet, if I can load them properly in Affinity Photo. Does anyone have any suggestions? Thank you. 20200724-Nikon-RKL_0353.nef
