Currently I'm using RPG keys and LR for weddings and C1 for everything else. The time savings from a one button push of "sync to previous" alone is immense. Saving 3-4 seconds per image times 600-1000 images times 30 weddings a year is a huge savings. I'd love to ditch LR for good, and I have customized and memorized C1 keyboard shortcuts, but it's not quite the same.
Most of the RPG functionality can be achieved using keyboard shortcuts and applescript. We touch a bit on this in our
Capture One Masters Program.
For instance you can assign a specific (pre-created) style, cycle through your style list, copy adjustments from the previous image to the current image, toggle between workspaces, access any menu tool (whether you can set a shortcut for it within C1 or not) etc.
Do be careful though. Automating some tasks can be great time savers. Attempting to automate others can be a black hole of time:
As an example, I wrote a script (triggerable by keyboard shortcut if desired) the other day that scans the crop of all images selected and sets the width/height of all images to the width/height of the largest width and largest height present amongst the selected images, without modifying the center of the crop for each individual image. Took about 6 hours to create and troubleshoot for all unusual situations. In this case the use-case is libraries/museums using our
book scanning systems and
autocrop tool hours every day, so the time was worth it. A good rule of thumb is make an educated guess how long it will take you to script something, then add a zero; I'm only sort of joking.
If you want to list the specific tools you use in RPG Keys currently and I'll give you a rough guess how long each one would take you to accomplish them by AppleScript.
