Some smart album rules not working
At a bit of a loss here - either my upgrade to Mavericks or my upgrade of Aperture to 3.5 has caused my Smart Albums to not work with various EXIF checking rules.
I frequently have rules which check the EXIF tag, Camera Make, and check if it is Canon - this allows me to filter out and focus on my Canon 5D3 photos and not get distracted in relatively pointless editing of iPhone snaps. Unfortunately it doesn't work. Camera Make is Canon returns no matches, Camera Make starts with Canon returns nothing, Camera Make ends with Canon returns nothing.
If I go and look at a photo, I can see the Camera Make exif flag says "Canon" in the field. No spaces at the end or anything silly. It used to work.
Anyone experienced similar? Anyone have solutions?
