    I've googled but can't find the answer to this.
    ISTR there is a way to tell iPhoto to rescan a photo if it has missed some faces, this time using a less 'strict' algorithm.
    The idea is if you have several people and it only spots a few, when you tell it to look a second time it might pick all the others up next time round rather than manually adding the missed ones one at a time manually
    Did I imagine this feature, or if not, how do you make it work?

    I've not read anything about this. But I'm so unimpressed with iPhoto faces that I barely use it.

    right+click/ctrl+click on the photo(s) you want to rescan, and select the option "Detect Missing Faces"

    To the OP: you can always rescan, but you can't do a 'looser' scan for faces. Maybe after start naming a few faces, a rescan might pick up more faces that it previously left out?

    Face detection works like a charm. Named my 6000 photos gradually and it only missed out a couple of faces over all those photos.

    Actually, Detect Missing Faces does use a more lenient algorithm. If you go to a photo that has a face in it but iphoto has not picked it up, Detect Missing Faces will, most of the time, pick it up this second time. I tried it just now.
