I've not yet updated Classic - along with most software I tend to wait a few days until someone else identifies the problems . Have to say that the update from the standalone LR6 to LR Classic was seamless and operationally it is much smoother, I like Dehaze and Range Masking and really 8.2 is much better than the standalone. The new texture slider looks an interesting addition.
As far as Photoshop is concerned I really haven't touched it yet, I did an introductory course locally which was OK but it was low level in it's content though to be fair it was free as part of a community sponsored course for old duffers like me !
Currently looking at getting some proper Photoshop training - my goodness it's expensive but despite all the videos online I would prefer to have that personal touch and hopefully I'll find something suitable soon.
I really like stuff shot around the underground in London but as an infrequent visitor these days I don't get much opportunity to do it. I do follow a guy on Flickr who does some great stuff and he has been doing a massive project in recent times. Well worth a look at - https://tubemapper.com/
