I right-click the image in LR and it pulls it up in PS in uncompressed format. After the retouching is done, it's then saved back to LR to be developed into a final JPEG.


uncompressed format = smart object = adobe camera raw = win!

Say you first do your Lightroom work but then want to do additional work in Photoshop. You do the Photoshop work on compressed JPEGs?


What Jamie said is pretty much LR editing 101. Right-click > Edit in PS. Preference set to PSD, or whatever you like. I never bother with layers for wedding work, so I use PSD. When done, close/save, and it's automatically added to the library and takes you right to it. I color code the original so it is not added to the final output. The PSD is the original at that point.

It opens in Photoshop as a TIFF with your Lightroom adjustments?

did you not try it? you can open as an original file, or with Lightroom adjustments. you can open it as a flat image, or as a smart object that once double-clicked, will open up the ACR adjustments (same as LR).

lossless compression is..... lossless
go ahead and leave it on


Found one down-side to compressed TIFFs. Made some ZIP-compressed TIFFs in Lightroom. Tried to open them in a file re-naming program [Canon Digital Photo Professional] and the format was not recognized. After investigating, I found that Canon's DPP will only recognize the LZW compressed TIFF, not ZIP.


On a side note, I compared the file weights of a single TIFF:

Uncompressed: 45MB
LZW: 30MB
ZIP: 28MB

Take a 16 bit TIFF, and a 1MB JPG of the same image, and print both to 20x30. You'll be hard pressed to find a difference.
