I have a general Catalog where I keep all of my one-off photos and stuff I shoot while putzing around. I have tens of thousands of images in there and it serves its purpose well.
However, there are times when my photography is event based (a major trip, a thematic set of photos) where one shoot may garner 4-5k shots. In these instances, my instinct is to dedicate a separate catalog — so I can focus just on those images and create smart collections, keyword sets, etc. that are only relevant to them.
OK, no problem, I can totally do that. But, it'd be great if all of my catalogues could be virtually linked so that, when searching or creating smart collections, I could check a box to search all catalogues vs. just the one I have open. This is useful for portfolio building or year-end slideshows where I am putting together a list of the best of my work and need to see everything.
