double tiff files

For about 4 weeks I have had the following phenomenon in Lightroom Classic 12.5 when outputting files to Photoshop. When I press the right context key and select the "Edit in Photoshop" command, then use Lightroom to write an additional Tiff file from the raw file before the file is output to Photoshop. I'm working on a Windows client with OS 10.x. The result is that doubles are created. One raw file and a second tiff from the raw.

 

where could be the mistake ?

thanks

 

 

I don't understand what you are doing in the step that I've highlighted from your original post. The "normal" process is to simply select the "Edit in Photoshop" item from the right-click menu, that will open a rendered version of the raw file into Photoshop. Once you have edited the image in PS, use the File>Save option and the Tiff (or PSD, depending on your Preferences) version of the raw file will be saved back into Lightroom Classic. So you end up with the just original and the derivative Tiff in the LrC catalog.

Can you explain what other steps (if any) you are doing?
