You will loose develop settings which will need to be recreated, but updating process versions in LR has similar issues.
For me LR perpetual is still the best option, but moving to CO would not be a major difficulty and it does add some good features that LR hasn't got.
Well, thanks, but the Develop settings is the KEY, the heart, of photo editing; the rest of it - star ratings, keywords, etc, is secondary. I don't know about you, but for me, most of the "sweat-equity" in creating good post-capture photographs is the time invested in "Developing" them. Lose that and I've lost significant assets.
Whatever we think about the pricing and the changes to the pricing, there are obvious, major benefits to the integrated workflow within LR from Import to Print, and that between LR and PS whenever we need to leave the "raw" domain and render the image. We can't take that away from Adobe, and it isn't clear to me that this strength is easily or fully replicated outside those two applications. None of that, however, addresses any particular justification for doubling the price of the subscription. If they are really going to do this, my mind is open and I would like to know why. Is it to increase rate of return to investors, are corporate earnings insufficient to sustain investor interest, or will there be incremental customer benefits to such a move? Adobe's customer base is huge, it has a lot of derivative intellectual capital in a way locked-in with this company and it has been loyal for many years, so we deserve, at least, to understand the reasons for what they are obviously contemplating.
