I have downloaded Lightroom 3 for trial before purchase. It is supposed to fully functional, but only for 30 days. I am testing it mainly for the collections capability since in another post you may learn that i am having grave difficulties with Bridge Collections dropping images like hot potatoes. Anyway, back to Lightroom 3 testing. I have edited Canon Raw images (.cr2) in Lightroom 3 and opened in Photosop CS5 only to find that many functions in PS are greyed out such as Filter Gallery. Surely there is some setting for this problem? Can someone please help me.
