Adobe are now accepting subscriptions to their Photoshop Photography Program. For $10 a month you get Photoshop CC, Lightroom 5 (and all future upgrades as they become available), 20GB of cloud storage on their servers and a Behance ProSite.
I signed up for the full Creative Cloud suite at the beginning of this year, thinking I’d try everything while still at the discounted price of $29 a month, but the truth is I still only use PS and LR regularly and InDesign occasionally. At the end of the year the monthly fee will most likely increase to the regular $50 a month which, for me, is too expensive. So I’m going to make the switch and downgrade.
You have to sign up by December 31st and own Photoshop CS3 or later to qualify.
