I use a combination of flags, rating, and coloring in my workflow.
I use flagging now simply as a workflow tool
I score my photos with ratings.
I use color codes to organize when I'm putting collections & sets together with diverse keywords.
Here's an outline of my normal process:
- Import from the card, assigning basic keywords.
- Set the filter to Flagged & Unflagged.
- Review pass #1: Reject ("X" key) the outtakes. They will disappear from view thanks to the filter.
- Review pass #2: Flag ("P" key) the favorable frames.
- Set the filter to Flagged only.
- Review pass #3: Rate the flagged photos.
- 0~2 = will probably get culled.
- 3 = good enough for facebook snapshots
- 4 = Good enough for clients, Flickr, Smugmug.
- 5 = Portfolio quality.
- Run my basic retouching edits - white balance, tone & contrast.
- Reject anything that I didn't like after the basic edits.
- Delete all rejected photos (Ctrl+Backspace, select "delete from disk"). I do this now, rather than later, because I don't want to be tempted and/or distracted by them.
- If I feel like I need to pull anything from the fire that I didn't "flag" before in order to round things out, I'll re-review the "un-flagged" frames.
- Refine Photos (Ctrl+Alt+R). This sets all the un-flagged frames to rejected and sets all the flagged to un-flagged. It's like resetting everything, except it keeps the ratings intact.
- Delete rejects w/ Ctrl+Backspace.
- Set filter back to flagged & un-flagged.
- Full re-touching edits starting with the top-rated frames and working down.
- I'll adjust ratings during this step; some get promoted, some demoted.
- I reject photos here too. Sometimes after a hard look during edit I hate the shot.
- Final review pass. Flag everything I intend to keep and adjust ratings.
- Refine Photos again.
- Reject all photos with a rating less than 3.
- Delete all rejects (Ctrl+Backspace) one more time.
I'm pretty brutal with my culling; I don't pack-rat shots anymore. I toss at least 80% of my shots in the bit bucket. My photos don't get better with age, and if I didn't like it today I know I won't like it next year.
