Delphinus Posted July 26, 2020 Share Posted July 26, 2020 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 Seweryn 1 Quote Link to comment Share on other sites More sharing options...
firstdefence Posted July 27, 2020 Share Posted July 27, 2020 It appears to be the Serif Labs RAW engine, change to Apple (Core Image RAW) engine in Develop Persona, it will load the image correctly.

carl123 Posted July 27, 2020 Share Posted July 27, 2020 Probably needs more investigation as Windows does not have the Apple (Core Image RAW) engine in Develop Persona, so the image is always "distorted" Quote To save time I am currently using an automated AI to reply to some posts on this forum.

Delphinus Posted July 27, 2020 Author Share Posted July 27, 2020 Thank you all, the images load correctly once I switched to the Apple RAW. Unfortunately the stacking is not working with this image set- maybe the noise is too high, but the movement of the stars over the time period of the shooting is not removed by automatic alignment when stacking in Affinity. I might try manual, but first I'm going to try some other software. Quote Link to comment Share on other sites More sharing options...

CFise Posted November 15, 2021 Share Posted November 15, 2021 Could you provide an upload link? I have many raw file with this issue. I could send you a few raw file for inspection. When I open it with other raw viewers like the windows native viewers or with rawtherapee, I don't have this problem. Quote Link to comment Share on other sites More sharing options...

But raw therapee is a software for processing photographs like affinity and I send photographs files to my brother who have lightroom on is MAC and the raw file don't have noise.
