compressed RAW artifacts XH2S

[Oliver111]

This problem has happened to me before, also on another production. I can't explain the reason, so I'm bringing it to your attention here. But the interesting thing is that the JPEG image is fine. I took a compressed RAW+small JPEG. Photo of the original compressed RAW+small JPEG on the link ( https://e.pcloud.link/publink/show?code=kZYB9DZtmM9s4g5CHhj9PAGaVLKqzbi0qjk ). I am also attaching the link of another user with the same problem ( https://www.dpreview.com/forums/thread/4703673 ). I used DXO Photolab 6, Affinity photo for RAW conversion, same result.

now I've figured out how it works FUJIFILM X RAW Studio, you must have connected camera to computer , this is result.

I tried the sample you posted in X Raw Studio and it gives the same problem as the other raw converter.

Can you post a link to the other raw - where X Raw Studio appears to avoid the artefacts?

Its probably a good idea to avoid shooting in compressed raw as it doesn't buy you all that much space over lossless compressed.

EDIT: I see you have now posted that you have the same problem with X Raw Studio - which is what I expected - the problem seems to be with the lossy compression algorithm that FujiFilm uses.

I tried to convert raw directly in fuji xh2S to tiff, this is the result

The answer to this problem is to not use compressed RAW. I see that there are 3 choices uncompressed, lossless compressed and compressed which I use

Those artifacts apparently only appear when using < compressed raw > under certain circumstances, a lot of the photos I took that day are fine. All photos from that particular location and angle have the same problem (strong backlight).

My request for the other raw file overlapped your post where you noted that raw conversion always showed the problem - even using X Raw Studio.

The bottom line is that its best to avoid lossy compressed raw to be safe.
