Sept 17 it becomes available. If your qualified and currently use only Photoshop CC single app you will be rolled over into the new plan..
I'm seeing conflicting info on what will happen next week when the Photographer subscription becomes available. I've seen an Adobe employee who participates in various forums say you'll need to contact support for the switchover and I've seen you say in several discussions that the changeover will be automatic.
Do you have a source for that info?
Just to answer my own question; I just chatted with an Adobe support person and they tell me that I'll have to phone Adobe to change my Photoshop CC membership to the special Photography bundle.
However, I'm not totally confident that the agent knows what they are talking about as the FAQ indicates that if you currently are subscribed at the $9.99/month level it will be automatic (which I'm not...subscribed in September).
