...CS 6 works great for me and I will like you probably keep this version until they offer something that cannot live without. It is a nice feature though
The one feature that I have found so far that I would really regret not having if I returned to CS6 is the new Camera Raw Filter.
It seldom gets mentioned, but I really like it. Basically, at any stage in the process, even up to the final layer, you can apply the filter and get back into Camera RAW (or maybe a virtual version of Camera RAW) and have all the RAW adjustments again available to you.
There have been many times in the past, when I've gotten near the end of editing an image and found that something just doesn't look quite right (for example, maybe the color balance seems a little off, the blacks might need strengthening, I've lost shadow detail, etc. etc.) With this filter, I can quickly get all the Camera Raw controls back and tweak the image.
It's really a great feature and I'm a little surprised it hasn't been highlighted more.
Other than that, I could live without almost everything else in CC and return to CS6 without feeling like I've given up a lot.
You can essentially do this same thing in CS6, by keeping your images in a smart object, no? You can adjust, etc...and still double click on the RAW image in the smart object (assuming you don't ever flatten images and why would you work like that, destructively?)...you can go to RAW, adjust,save and come back to PS and keep going....
Yes and No. As long as you keep the layers as smart objects and create multiple smart object layers you can double-click on the layer and return to RAW. But, it's not often easy to keep every layer as a smart object throughout the workflow. Some plug-ins don't always play nice with smart objects and even some PS functions don't work with smart objects.
Once you've merged any layers or merged any filters or masks with a layer, you no longer have a smart object. While you can open something as a smart object, it is a bit of a pain in the rear.
The beauty of the RAW filter is that you can get back into RAW at any point in the process. For example, suppose you've gone through and applied some effects using a NIK or OnOne plug-in, or you've done some tweaking of various channels in PS, and then, near the end of the workflow you say: "I really like the effect, but I wish the blacks were a bit more intense and I wonder what it would look like if I warmed up the scene just a bit."
With the RAW filter it's a very simple step to go back and fine tune that image at the end of the workflow.
It's just a very simple, one-click solution that wasn't readily available before.
