Hi there,

have an issue with Canon RAW Imports in Bridge and Photoshop. Many Picture have stripes and other errors like this.

The picture is made by Canon EOS 7D, 15-85 OBjective. The camera and Objective was in Maintenance by canon. with out any effect.

During the import to Photo-Shop I do have effects like this. When I open the RAW-Files with Windows Foto-Viewer, the picture is normal without any errors. So far seems the Camera Raw (10.2) Installation is not working.

Where are coming this effects from?

Best regards

Günter

Im Foto-Viewer (Standard Windows 10):

Go to Camera Raw Preferences and uncheck "use graphics processor":

Unless you have a 4K monitor you can just leave it unchecked, it doesn't do anything useful. If you do, however, check for a driver update.

Thanks for this idea.

Even if it is checked or unchecked, it do not change anything.

The driver are up to date (PS, Camera Raw and Grafic card).

Their must be an other clue. Any ideas?

OK. I was trying the "soft" option first. If that isn't it, these files are really corrupted.

Windows "Photos" doesn't show you the raw data, just the camera-generated, embedded jpeg preview. The jpeg preview is a very small component and can be fine even if the main file is corrupted.

File corruption can happen in any hardware component. Usually it's a failing disk drive, but it can also be RAM, or minor components like card reader, USB cable...anything in the chain.

Backup everything you have ASAP. Then try to narrow it down.
