when I right-click an image (CR2) and select "Edit in Photoshop" Lightroom first creates a TIF. Can I turn this off? Or what is the point? Is this actually useful? I normally optimize the Raw-File in Lightroom, open it in Photoshop and edit it a little and then save it as a PSD. Is TIF more preferable? Or why does Lightroom do this?

Go to Edit->Preferences->External Editing. There you should be able to choose the desired format (TIFF or PSD)

Here's more info on this from Adobe.

Concerning the advantage of TIFF over PSD, see Conor Boyd's comment!

    There are quite a lot of advantages of TIFF over PSD; see the link in my comment above.

  • I have to admit I also did not know, that TIFF is so versatile as a container. As it can seemingly provide everything PSD can handle as well, I have to fully agree with you that TIFF seems to be the better choice. Thanks for pointing this out.
