I use Lightroom as the title suggests. My question is about the use of catalogs and how often people use a catalog before starting a new one.
It seems that the more photos I import into Lightroom the slower Lightroom will work.
Also do people use more than one catalog at a time: use one for certain photos and another for different photos switching back and forth depending on what photos go where to organize more than just using collection and collection sets. This is my way of organizing my photos with collection and collection sets. So is it a good idea to often start new catalogs and if so when is a good time to start a new one? I.e. generally about many photos would be in one catalog before making a new one?
