I've scanned through the faces again and the pictures with identified faces. What I found is that there are LOTS of pictures that have *some* faces identified and others equally visible, indeed, faces of people recognized in other photos, that aren't detected by Picasa.

So. I've rescanned the whole collection, and the first total after this second scan produced almost 50,000 unidentified faces. That number is down to 28,005 now.

A neat trick I learned by accident has to do with a couple of sliders in the program. One slider is used to zoom into the picture. When you grab the slider, you can drag it to the right for increased magnification. There's another slider up at the top that is used to filter by date the pictures shown. I've used this second one a lot to reduce the working set of pictures with faces I have to make decisions about. As I dragged the slider to the right, it filters out older pictures. The further to the right I drag it, the set of pictures displayed is smaller and newer. This is useful, but difficult to manage the slider one pixel at a time, because the time scale is not strictly linear. And at the oldest ranges, I might make a tiny physical change and have the time threshold change by a year. At the right hand side of the scale, the same physical distance on the slider might represent a much smaller time delta, perhaps only one month. Making tiny changes at the older ranges was tough.

Then, I accidentally moved the cursor over the slider *and* accidentally rolled the mousewheel as the cursor was over the slider range and the slider moved one increment with each wheel detente I turned through! This is awesome! I tried it up at the top on the time slider, and it worked the same. So, now I can make the most granular changes to the time scale. This lets me divide the pictures into sets that are more easily understood since I take them in batches. Seeing them all together makes it harder to identify the faces since I have to shift contexts for faces I don't immediately recognize. I'm happy I found this kind of control in the interface.
