ACR Saving file as 16 bit Tiff vs RAW file?

2 years 3 months ago #679567 by Photo Amigo
As a greenhorn ACR user, I have a couple questions, or one for right now.  If you have a photo and you save it as a 16 bit Tiff file, does that have any advantages vs a RAW file if it's going to be edited in Photoshop after?

Any benefits?

A little hard to explain so it makes sense. Firstly, you don't actually edit a RAW file. What you are doing is creating a set of instructions that will be held in a sidecar file that will be applied if you decide to open it in Photoshop. When the file is opened it is then converted. If you do a bunch of edits to a RAW file with ACR and just close it without actually opening in Photoshop the edits aren't applied directly. In other words if you went and deleted the sidecar file for that RAW file and reopen it in ACR, it will be as if nothing was ever done. If you had already opened and saved as a tiff or whatever, those settings would have been applied and cooked into the tiff. So is their an advantage to saving as a tiff first? No and especially no if you didn't do your edits in ACR. In other words if you just opened the file in ACR and saved as a tiff without making adjustments, you will severely compromise you ability to edit the file later. Hope that helps. Feel free to ask further if you need clarification.

I'm going to add a few more words, in support of Randy's explanation.

RAW files are source material only. They are only created by the camera. When you edit them, you have to save the results in some other format (PSD, TIFF, etc, depending upon your software) but you never create another RAW file from software.

Lightroom (which uses the same ACR engine) records your editing steps and applies them to the source material. You don't get an image until you export it with those edits applied.

Since you only mention ACR, it's not clear what your workflow is....
