Andreas, great idea to start this thread. And while you've set it up to share your experiences with C1, i hope you don't mind me writing up my usual workflow.
1. I start with downloading the images from card to hard drive. I use the inbox concept (sometimes called dropzone) where all images are placed.
2. I then import them into photo supreme (PSU), my catalog system.
3. I've setup PSU to drop the images into a date folder from the inbox. It's just the import date.
4. I then proceed to review and give an initial keyword (set).
5. I then proceed to do a first rating the images in PSU.
6. After these steps, i move the images to my hard drive archive folders. These folders are in my backup routine.
7. Then i run through my selection once more and send the chosen ones to C1.
8. In C1, i'm in session mode, i process the images to my liking. I hardly ever go to another image processing application (Except for HDR, Pano, or other stacking).
9. In C1, i've recipes setup for my usual output channels, like NG and my own (private) web site. These deliver the file type, image dimensions, colour space and file size of my requirements. A recipe usually outputs in one directory. I typically choose a directory manually, but output to original image directory is an option and it's possible to enter subdirectory of choice, or based on job name.
10. After output, i usually update PSU to import the new output files (verify folder). PSU tracks file versions based on a configurable scheme (i've part of original file name).
11. Then, it's all about coming back to the images in PSU to lift images for posting in NG threads
Hope this gives people an idea of how it could be done. Questions can be asked and answered
