I am undecided about Lightroom CC, but do want Lightroom 6. Can I buy LR6 and then 'add-on' the CC benefits, so that should the situation arise where i don't find them useful, that i can let the payment for them lapse and revert to just the original standalone LR6 programme which will retain full functionality? What i don't want is to buy a LR CC plan, and not use it fully, but not be able to use the develop module of LR when the membership ends. Apols if this has already been asked elsewhere but i havent been able to find the thread. thanks.
