Lightroom Fehler B&W (BUG)

How do the two appropriate files from the others? What's format have the original files?

Do they only become black and white photos after editing in Photoshop or were they perhaps created with a black and white profile in the camera?

You've already don't answer several of my questions.

• What happens if you open the file in Photoshop again?
• What happens if you save the picture as a psd file?
• What happens when you update the 1:1 preview?
• Which mode do you use in Photoshop for the image, ex. RGB/16bit?

Please provide a copy of your 'System Info' in LR and PS. This can be get in LrC and Photoshop from Help > System Info menu item. There's a copy button in the System Info dialog. Press this button and paste the info into your next forum post.

Look in the Profiles section in Lr Develop:

Danke für deine Antwort! 

Ich bin überall auf dem aktuellen Stand. Es passiert auch nur bei zwei Dateien. 

Bei Photoshop kommt diese Datei in Farbe und kann diese auch dementsprechend abspeichern. 

Wenn ich diese Datei in Lightroom öffne, ist diese für 1 Sekunde in Farbe und dann in B&W.

Dies lässt sich nicht ändern. Bei mir steht nur, dass alles auf dem aktuellen Stand ist. 

Ich werde mir in meinem System nochmal alles genauer ansehen. 

Woran könnte dies noch liegen? 

Which version of Photoshop and Lightroom do you use?

What happens if you open the file in Photoshop again?

What happens if you save the picture as a psd file?

What happens when you update the 1:1 preview?

Which mode do you use in Photoshop for the image, ex. RGB/16bit?

Is your system up-to-date? Do you have installed all recent updates and patches for the operating system and the device drivers, especially the graphic driver. If you have a NVidia graphic card installed, make sure that you are using the recent Studio version of the driver, not the Game Ready version.
