"RAW" and "movie" keywords no longer automatically added
After a recent iPhoto update -- I'm using version 9.3 (650.39) now -- I've noticed that both the RAW images and the movies that I import from my camera are no longer automattically tagged with the keywords "RAW" and "movie". In previous versions, after I imported a RAW file or a movie from my camera into the iPhoto library, it automatically added the appropriate keyword (I could see the keyword by clicking on the image or movie after the import and hitting the info button). Now, that automatic tagging seems to be gone, although both those keywords still exist, and my movies and RAW photos from before are still tagged. Has anybody else noticed this? Is there a workaround, or does Apple just need to fix this? Or was it discontinued on purpose?
