Like the title says, I would like to filter by the "Exposure Bias" (what Lightroom calls exposure compensation) value. I can make exposure bias appear in the metatdata panel and in the info toggle, but I can't see a way to add it as one of the metadata fields in the metatdata filter, nor have I been able to design any text search in the text filter that returns accurate results (whether I search all fields, metadata, or EXIF). Anyone have any ideas on how to do this?
(The background is that I have tons of autobracketed shots; I would like to, say, filter them so that only the +1 shots are displayed.)
