EOS R5 - How Do I Remove This Grid Pattern?

[peterdenio]

Canon R5, RF 100-500 lens, F7.1, ISO 200, Shutter 1,000/sec

I've looked at "View", "Grid" to no avail. Any thoughts? getting this on some but not all from this beach series.

Since not all photos are showing the issue, then I would lean more with others in suspecting a bad media card or card reader.  i.e. the files somehow became corrupted.

If you have a different card, try using that for a while and see if the issue returns.

How do they look on the back of the camera?  Knowing that info would narrow down the problem.

Share an affected raw file.

I agree with Peter. You really need to post the Raw or Jpg strait out of camera (SOOC), with no editing. You will have to use a file sharing site like Dropbox, One Drive, etc.

I noticed you used Topaz Labs DeNoise AI and Sharpen AI along with PS and others. Did you per chance use Topaz Mask as well? I ask because there is a bird in the background pattern that isn't effected by that odd background as if the background has been replaced by another image.

I do not see this pattern through either viewfinder. Thinking now maybe more of a Photoshop issue than camera issue.

If using a card reader to transfer files from the memory card to your computer, try another card reader and USB cable. You may have corrupted the files during downloading to the computer.

Another Adobe user got the same problem yesterday with R6. Perhaps an update that went wrong? Try DPP4 and see if the problem is still there.
