I fully accept that most people would rather have the backup reminder at the end, and therefore that should be the default. But surely it would be trivial to have kept the old functionality as an option? To have not done it that was is simply ridiculous.
I always switch off my computer, simply because my home MacPro often doesn't get switched on for days at a time: I basically use it for photo processing, and not being a professional photographer I don't have cause to use it every day. Usually I carry on late into the night until I realise that I really need to get some sleep and want to turn the thing off and walk away. Not wait 5-10 minutes for the backup. On the other hand I always have 5 minutes to spare when I'm booting and going into LR. To get a cup of tea perhaps before I start working on my images.
For grain I am currently using DXO Filmpack, which is MUCH better. But maybe there is stuff that I cannot see how to do, or how to do well. Hence the desire for the tutorial.
The new import dialog certainly looks like it has far more functionality than the old, but after a simple upgrade stuff that it used to do fine it now no longer does. Hence the desire for the tutorial. [Edit: I used to use presets extensively, being a bit dim I prefer to set these things up and then leave them alone. Reduces user error. The old presets were still there after the upgrade. But they don't produce the same results, probably something I'm doing wrong. I'm not very bright. *sigh*]
As for the alleged performance enhancements, so far I haven't seen anything noticeable. But I'm no expert. Hence my desire for the tutorial.
As to the alleged image processing improvements, so far I haven't seen anything noticeable, but I haven't really had time to spend scouring my images for small gains. If some experts were to produce a tutorial then I would realise WHERE I should be looking, and perhaps which images might be likely to benefit from being revisited.
One thing that I was very curious about was the Web Output module, it has always seemed to be such a weak offering that I was surprised it was included at all in an otherwise excellent product. As far as I can see it has not been improved at all. It's still terrible. Perhaps all the engineering went into the other parts, and that's fine of course - just surprised that even in V3 it's so shocking.
I still love LR. Great product. Rather have LR than PS if I had to choose just one.
But everyone has been making such a big deal out of the V3 upgrade I was expecting to be wowed. Not so far, but I reckon that's probably because I haven't spent enough time trying to learn the new features. The help system is hopeless, and the simple lists of new features on the Adobe site have left me underwhelmed once I had actually bought the upgrade, though they sure did look enticing.
So... I'm keen on purchasing the new MR & JS tutorial. Even if Jeff does think I'm an idiot, I think he's very entertaining, and more importantly has a great deal of knowledge to impart and the LL tutorials present it in a very digestible format. Photography for me is just for fun. If it was a job I'd have to RTFM. :-)
