who me? wrote in post #9855708
As one who has Lightroom sitting on a shelf waiting to be installed (no time to install recently). Also not having a usable workflow due to lack of decent tools, I will be establishing a workflow that I can actually use, this may be a dumb question but....
Why convert to TIFF files?
The tiff format is a "universal" image file format that has two quality levels -- 16 bit and 8 bit but is not compressed as is a jpeg. The 8 bit tiffs can be read and processed in pretty much any image editor. The 16 bit tiffs can be processed by some apps such as Photoshop while retaining more image data.
If you are shooting in Raw and need to move from a Raw processor such as DPP to an external app such as Photoshop, you will need to take one of two approaches: if you are using Photoshop CSx you can transfer the image directly into Photoshop initially skipping a "save a tiff/jpeg" step, or for any editor you do a Convert and Save to create either a tiff or jpeg so the external editor can open and process the file with all the DPP/Raw edits applied.
You should know that each Raw processor only "reads" its own Raw editing, which is why you can't make adjustments to a Raw image in, say, DPP and then open the same Raw file in Photoshop Camera Raw and see those edits applied.
If you are shooting in jpeg, there is also an advantage to saving a tiff copy if you plan to edit it: each time you save a jpeg the jpeg software performs a new conversion with at least some compression at whatever level of quality/compression it is set to. It is pretty common when you are getting started to find that an image that was in the beginning a high quality jpeg to, after a few saves, has all of a sudden become a low quality shot. So, good workflow is, once you open a jpg image into an editor, do a Save As and save a tiff for editing uses.
My normal workflow is to do as much Raw processing as possible (I use Lightroom) and then to go into Photoshop only if an image needs something my Raw processor can't provide. I tend to prefer avoiding the large tiff copies if I can
