I started using LR with a new catalogue every year, then I merged them (and lost the published collections). Now I started digitising the family albums outside of LR because I thought I had to use Photoshop but actually I can do everything necessary to invert a negative in ACR opened from Bridge. PS turned out to be totally useless for the task. If I can do it all in ACR then I can do it all in LR. This has some advantages if I'm working with camera images of 110 film as I typically get two film frames per image and I could use original + virtual copy to give me the "two" film images from the one digital image. This makes it much easier to trim white balance across several images. In Bridge + ACR you can only "see" the latest frame. To see the other one means opening ACR and moving the crop window. So I'm trying to decide whether to add the images from film to my master catalog or separate them completely. I'm at 23k images (since 2007) and will probably add 5k digitised film images. So, if I survive another photographic decade and take more pictures that'll be, say, 60k images in LR. Is 60k images too many for the catalogue? There are articles that say LR will cope with millions. What I don't want to do is to have 2 big catalogues then decide to merge them at a later date as this risks losing the published collections again. Ho Hum? What to do ?
