Most of the sliders have the same names, but are organized somewhat differently, and while it is a mental exercise to learn what is where in CC since it is different from Classic CC, I will say that the organizational grouping, is to me at least, more logical. You can call it simpler and cleaner, and as such is well suited to engaging with users who have not been or are not serious photographic editors. The first thing you see, is that Lightroom CC has a very different user interface. Since I get it anyway, I thought I would see if and how Lightroom CC could help me given my decision to keep my images on my own storage, not in the expensive Adobe cloud. However, if you sign up for the Photography Bundle, you get Lightroom Classic CC, Photoshop, 20GB of cloud storage (because you will be storing your images locally) and you also get Lightroom CC. Each additional terabyte costs you $10 USD per month, which if you are a volume generating photographer will ensure that you are eating cat food and living in a refrigerator box in no time. You can actually have local copies, but the main storage is in Adobe's cloud. If you sign up for the CC plan, you get Lightroom CC and 1 terabyte of cloud storage for your images. But after watching Scott go through his class, I gave myself a project to see if Lightroom CC could be useful to me, as an add-on to Lightroom Classic CC but not as a replacement. In that stead, Lightroom CC joins the ranks of Polaar and the herd of other smart device editors. It is for folks who make a lot fewer photographs, folks who are probably happy with the pictures that they take on their smartphones, but who want to play at photo editing to some extent. Lightroom CC is plainly designed not for me.
Like the mc marketing weasels ran into traffic without talking to customers. I found the renaming of Lightroom CC to Lightroom Classic CC and Lightroom Mobile to Lightroom CC to be well past and around the corner from stupid. I recently took a class by my friend Scott Kelby on Lightroom CC. I don't want every image to look like every other image. I don't care for presets or rubber stamps or automatic looks.
