I take multiple pictures of flowers with differntet areas of focus and create a single image by opening them in layers in Photoshop from Lightroom classic but for some reason, I am no longer able to do that. As they begin loading in Photoshop, they all disappear and I am taken to a differnt screen.
Sorry that the "Open as layers" in Photoshop is not working in Lightroom Classic.
Would you mind sharing the version of Photoshop and Lightroom Classic you're using?
Are you working with a Windows or Mac OS? If using a Mac, are you working with the latest Mac with the Apple's M1 processor? Note that there is a known issue, multi-app workflows, such as Copy and Pasting or Editing in Photoshop from Lightroom, between native and Rosetta emulation versions of Adobe applications will not work.
