But Photoshop is *not* a workflow software at all. With LR you are using a database of your photo library and take care of it. [...] It is just not about the time you need for one picture. It is about the time you need to sort and edit hundreds of pictures.
This was key for me. LR has everything you need to quickly sort through thousands of photos, tag the keepers and flag the garbage for deletion. Once I got my workflow down I could pare down 1000 frames to 20 odd shots for publication in under an hour.
Well that’s all fine, but the topic under discussion is “post-processing software”, not “photo library organizing and tagging software”.
I think Lightroom is fine as an organizer, but I wouldn’t use it for producing final output of any photograph that matters.
When I produce prints with Photoshop starting from “raw” camera files, I zero out all settings in Adobe Camera Raw, import as 16 bit/channel ProPhoto RGB image (for most images another RGB profile would work just as well, but sometimes the extra range helps if there are very blown out regions in one or more channels), and take the image straight to Photoshop. The first thing I do there is convert to CIELAB mode. Then I use a several actions of my own devising to create a bunch of my own adjustment tools.
The actual arithmetic done by Adobe Camera Raw (and therefore by Lightroom) is basically wrong, in my personal opinion, and even the most trivial adjustments end up distorting color relationships and losing information in ways that are difficult to recover later. For most images the resulting appearance may be acceptable for many photographers, and that’s totally fine. I personally find I can always get a better result using only tools in Photoshop and entirely ignoring Camera Raw. [A different raw processor might provide some better tools than Adobe’s, but I’ve never done a proper in-depth investigation. It’s on my long-term todo list. I don’t have any experience Capture One.]
