From a workflow perspective I have always saved my files in the TIFF format. I'm sure I had a reason back in the day, but if I did, I have forgotten why. With the recent LR/ACR updates you can now save files as PSB files, which have no size limits. Although I have moved more of my processing to ACR and I haven't run up against the TIFF file size limits, I have in the past and I am sure I will again in the future. With that in mind, are there any cons to saving files in the PSB format rather than using TIFF?
Bear in mind that I generally save one copy of the file with all of my adjustments included in the file in case I need to go back and modify. I will also have a working copy of the file that I use for printing that has been flattened. My question is more geared to the larger file.
Appreciate any input you may have.
