DAM wise LR is brilliant but I’m not bothered about a raw editor being a good DAM, I just want it to be good at editing photos. I use Digikam which is as good as LR for everything that I need. That way I can have all my photos and other things together, I can use different editors and I can use the dev versions without any worry. To be brutally honest I don’t like DT as a DAM but even if it did everything that LR did but even better I still wouldn’t use it as my main DAM because these things being separate suit me.
I do use some of DT’s DAM features so it’s handy editors having them but they should be basic IMO. So DT doesn’t any missing DAM features because it’s a raw editor, would be my response to the people complaining. I just don’t give a DAM.
