I included this topic in the Guide to Adobe Bridge: Organizing a while back (has it really been over a year?), but I wanted to mention it again. This quick little tip is aimed directly at the users of Adobe Bridge and/or Adobe Lightroom, though it may apply to other photo organization software as well.
Sometimes we get busy with things and the photo archive keeps filling up. If you don't have time to process all your photos immediately, you should at least label the photos and/or their containing folders rather than try to remember which photos have been processed. Simply adding a color-coded label to my folders and photos has saved me a ton of time by eliminating the need to sift through thousands of photos each time I want to process a few.
As soon as I create a new folder in the archive, it gets a red label (that's my “To Do” color). As I start to work on photos in that folder, I'll change it to yellow (“In Process”). And when I'm done, I'll change it to green (“Complete”). These labels at the folder level keep me on track and tell me which sets of photos are being worked on or still need work. As you can see in the image above, there's no guessing at what needs to be done next.
I do the same type of labeling system with my photos — red, yellow, green. One of the first things I do after importing is apply red labels. These are the photos that I'll consider for processing at some later date, usually 1/4 to 1/3 of the full set. Now, using your label filters, you can weed out the junk and focus on the good stuff. After a photo has been processed and exported, I'll apply a green label so I don't have to keep looking at it while processing the unfinished photos. This method also gives you a sense of accomplishment as you watch the red counter go down and the green counter go up over in the filter panel.
What do you use to keep track of your unfinished and finished photos as they stack up in the archive? Labels, tags, stars, folders, something else? Everybody seems to have a different way of handling these things, so I'm curious what's working and not working for others.
