+1 to all that, but please don't remove sessions. I live and die with those.
I actually really like Bridge for key wording and metadata, as well as a first look at images. It is pretty easy to pass images back for forth between Bridge and C1 since they are both browsers. If I am shooting tethered, I go direct into C1, but if I'm shooting to cards I start by setting up a tethered C1 session with my naming convention (YYYYMMDD_client_project for paid work or YYYYMMDD_location for personal/stock/fine art). I copy the cards to my hard drive, rename the DCIM folders and move them into the session folder. In Bridge, I rename the files (same as the folder name with a three or four digit number), review and keyword the images and move them to the C1 session Capture folder (or multiple capture folders depending on the shoot). When I shoot stitches I will put my hand in front of the lens and the beginning and end of the series so I know where a series starts/stops and I can be sure to keep those images together. From there, everything goes back into C1 where images are processed as 300 ppi, 16 bit pro photo tiffs as saved to the session Output folder. Back in Bridge, I will open the Output folder, modify the images as necessary in Photoshop, and save the working files back to Output and the final flattened files to the session Selects folder. At this point the entire session folder is copied to backup and archive drives and deleted from my edit drive. This works well for complex images, but is way overkill for personal work.
First of all, if any of you have recommendations to improve efficiency, I'm all ears. Second, this is clearly a workflow that should be perfect for C1 catalogs (sorry, they don't really work that way), or Media Pro (it can work that way, but I don't love the cataloging features). Instead, I import the entire folder into Lightroom, which is messy and kind of a headache.
