Missing Images in Photo Mechanic
When doing a Catalog Sync, there are almost always photos that show up as Missing, which is indicated with a yellow circle to the right of the filename in the viewer window. The motherlode of Missing images can be found under the Collections tab once you select one or more of the Active Catalogs in the upper left corner. Then click Collections and the catalog in question under which you'll see -sync- and below that, the most recent syncs. Click on the oldest one and you'll see Missing and sometimes New. Click on Missing and PM will bring up a tab named Collection: Missing. Click on the tab and you'll see all the images that turned up Missing in this sync.
Technically, you could just select all the images and delete them, but I'd rather be more careful. So I go through each of the shoots under the Missing tab and ask myself "why would images from this shoot show up missing?" One example is when I change the filenames. For example, I've recently added "NOLA" to the beginning of the filename on every shot taken in New Orleans because I have thousands taken there and have begun naming the files by neighborhood name. And while Bywater is the only neighborhood I know with that name, there's a French Quarter in both New Orleans and Charleston, and possibly other cities as well, so images that sort by neighborhood name can be confusing.
Another reason would be if I'm processing images and moving them deeper into my folder structure, which works in this order (see Photo Workflow posts): 1 scratch fuzzies, 2 Set GPS & base metadata w/neighborhoods, 3 rate & set classes, 4 tag & process, and 5 set finder color. If I've moved any image from a lower-numbered folder to a higher one, PM won't find it where it was earlier so it will show up Missing.
Once I've satisfied myself that images from the shoot in question really are missing, I select all of them under the Collection: Missing tab and delete them. And it's a good idea to do this fairly frequently because if you have thousands of Missing images, it can take quite a while to delete them all. And no, I've never been unable to come up with a reason a shoot's images should be Missing, so PM has always done its job, but I'd rather be completely sure before deleting images I can't get back again.
