With Lightroom 4.0 (64 bits), everything goes normal. When I clicked "Edit in Adobe Photoshop CS5.." the edited raw file was exported to CS5 photoshop in "tif" format.
After updating Lightroom 4.1 today, LR no longer generates "DSC-1234-Edit.tif" and exports to CS5 photoshop in "NEF" format. It appears that there is a problem with LR4.
How can I fix this problem? I am running Windows 7 Pro (64 bit) with 8 GB RAM.
It isn't a problem, and it isn't anything that you should worry about. Lightroom 4.1 is compatible with ACR 6.7, which is compatible with more cameras. You really are not working on the raw image data. That only indicates where the data came from. Since Lightroom and ACR are compatible, the creation of the TIF file will be done at the end of the Photoshop session rather than at the beginning. Everything is working the way it should.
I am working on raw images. I am shooting NEF with Nikon 7000.
LR 4.1 is a problem. Editing NEF files in in development module works fine but It does not produce tif files at all.
I restored to LR4.0 (I now restsored a mirror image of Windows partition conaining LR 4).
LR4.0 produced tif files with the same raw files used in LR 4.1 and exported tif files to Photoshop CS5.
It looks that I should stick to LR 4.0.
When Lightroom and Photoshop/ACR are out of sync, the TIF file has to be created first in order to include all of the Lightroom adjustments. If the programs ARE in sync, then ACR is able to translate the Lightroom adjustments to and pass them on to Photoshop. The TIF file doesn't have to be created until the end of the Photoshop editing session. It's working the way it is supposed to, and there is nothing you can or should do to change it. Really.
I realize that when you are in Photoshop it will appear as though you are working on the NEF, but when you save your work in Photoshop it will save the TIF or PSD, depending on your Lightroom preferences.
