I am trying to find all my 32 bit HDR images in Lr 5.7.1 but I cannot find any way to search or filter on bit depth. Nor does the Metadata panel in the Library module show any indication of bit depth. The information is available in Bridge (shown below). Can Lr search or filter by bit depth? (I know Geffrey Friedl has a plugin that do this search but can Lr do this natively?)
You can use the Color > Bits Per Channel criterion in smart collections. (There is no equivalent filter criterion.)
The Bits Per Channel smart collection will work perfectly. Thanks!
