Hi everyone,

I need some help. When I open my RAW file in Darktable 5.4, dark areas appear in the corners. I’ve tried to fix this using lens correction, but I just can’t seem to get it right.

Under the Lens Correction menu item, I can select my camera model, SONY RX 100 M7. But I always get the message “Camera/Lens not found,” even though I selected it correctly.

Can anyone help me get rid of the dark spots in the corners?

Research direction

Begin with the Lens Correction module and the SONY RX100 M7 camera selection; reproduce the “Camera/Lens not found” result on Linux Mint with darktable 5.4 using the affected RAW file. Done means the camera and lens are recognized and the corner darkening can be corrected without the reported error.
