I’d like to start using the DAM features of PhotoLab, but one of the obstacles I’m facing is being able to search for unusual EXIF information. Case in point: I’d like to find photos taken using a fully-manual Samyang 7.5mm f/3.5 fisheye lens in micro four thirds mount. The lack of electronic communication between this popular lens and the camera body (Olympus or Panasonic) means the EXIF information in these RAW photos includes aperture “f/0.0” and focal length “0 mm”. These don’t show up as 0 in PhotoLab, however: they show up in the metadata palette as --. After indexing the folders including these images, I tried searching for 0, 0mm, 0 mm, or f/0.0. I get results from some old Canon cameras whose images have f/0.0 for some reason, but that’s all. For some reason, PL can’t find the fisheye photos - neither RAW nor JPEG files from my cameras are found.
With a bit of experimentation, I found some of the fisheye photos by searching for NO-LENS. But only a few of them show up - those taken with a Panasonic GX85, which writes that particular keyword into the EXIF. I’m still looking for a way to find the fisheye images taken with an Olympus body (E-M5 II, E-M1 II, E-M1 III, E-PL5…). But the actual EXIF info containing zeros is unsearchable!
The only other distinguishing characteristic of these images is that they have no DxO optics module. But my images are spread out across many folders spanning many years.
Please make the metadata search capabilities more robust so that this isn’t a problem. Something more interactive than an all-purpose word match would be very helpful. What might work is if, after indexing, I can see a sorted list of different values in a given EXIF tag and choose a blank one or a strange value if I wish. This would let me find images taken using adapted lenses, too - anything that can be mounted but not controlled due to a lack of electronic communication between the lens and the body. As it is, the DAM search feature is way too primitive.
