P: Strange moiré patterns with high ISO images with Lens Correction

I was editing some events photos and started noticed a strange pattern with low light files, and with the Lens Correction feature activated. I increase the exp so you can see better the lines. ISO 6400. Check the file

Hola,

al trabajar con archivos raw de la canon Eos R5 que se han disparado con isos altos de 3200 o 6400, y no estan del todo bien expuestos, al subir la exposición o recuperar sombras en Lightroom aparece un "banding" con unas lineas "circulares" que nunca me había aparecido al revelar otros raw de canon de otras camaras como la 5D markiV.

Alguien tiene el mismo problema o detecta algo similar??

Problema solucionado, solo hay que darle una reseteada al LR:

Buah! Gracias! Llevaba cantidad de tiempo buscando y no encontraba la razón del porque pasaba. Totalmente, desaparece si desactivas la corrección de lente en lightroom o simplemente bajas la distorsión!

Mil gracias.

I might be wrong, but my understanding of 'Mirrorless' camera models is that Lens Correction is already applied by the camera. Trying to apply it again in LrC may have the consequences you are seeing.

 

Regards. My System: Windows-11, Lightroom-Classic 15.1.1, Photoshop 27.3.1, ACR 18.1.1, Lightroom 9.0, Lr-iOS 10.4.0, Bridge 16.0.2 .

Zoom in at 100%; (1:1) in Develop module; do you still see this?

Morie is often visible on some images when you zoom out as the preview has to be subsampled down.

Yes, at any zoom... I exported the file, this is not a capture, but the exported one is worst. When I deactivate the Lens Correction, the pattern goes away

Try disabling GPU in preference: better?
