What is DRM and handling of plugins such as Nik Efex like in C1? Thinking about running LR 6 for historic/catalogue images and possibly swapping to C1 as main editor. Never really felt *completely happy* with dxo stuff, and On1 was always a bit clunky.
Just keeping options open at this stage.
I'm not sure what DRM is, but with plugins, it depends.
C1 now has a plugin interface, but very few plugins use it. Helicon Focus, and Jpegmini plus some online services are the only ones I am aware of. ON1 say that there Plugins work with C1.
However, for a long time, C1 will run, as a plugin, anything that has a stand alone option. This includes most, probably all, Nik plugins, Topaz etc. DXO apparently broke this with the latest release, but after just saying the "don't support C1" the latest from C1 forums is that a point release of the Nik plugins has fixed this.
C1 has a right click option to "open with" or "edit with" which both open a context sensitive menu, which lists things like Silver Efex pro or other programs on your computer.
If you select Silver Efex pro, from the "edit with" option, C1 creates a TIF/PSD beside the raw (embedding any C1 edits in the TIF/PSD) and then opens the TIF in Silver Efex pro. Any edits you make in Silver Efex are saved in this TIF, which is already "in" C1. When you shut down Silver Efex, you can carry on tweaking the TIF in C1.
I use Photoshop as a "plugin" to C1. The C1 "Edit with" option creates a PSD, which includes any C1 edits to the RAW, and then opens the PSD in Photoshop.
All edits in PS are saved in this PSD which is already in C1, and I can carry on editing the PSD in C1, when I close Photoshop.
If I want to tweak the underlying PSD, I can reopen it in Photoshop using the "open with" (not "edit with") option in C1. In this case the C1 edits to the PSD aren't sent to Photoshop.
As an example of this. I might do some initial editing in C1, then do noise reduction in a layer in Photoshop, and then come back to C1 for further editing. If after editing the PSD in C1 I decide I need to tweak the noise reduction, I can use "Open with" to go back to PS to tweak the noise reduction without affecting any of the C1 edits.
I don't really use Plugins anymore, but those that I do (sharpening and noise) I use via a layer in PS (or Affinity Photo) and round trip from C1 to PS as described above.
I don't want to get into a C1 vs LR argument, but I just drifted away from Plugins when I switched to C1.
This is much easier to do than describe :-(
