As title says, I'm trying out Photoshop CC 2018 and I absolutely love it, I'm planning on buying it and found this plan Photography 20GB which supposedly includes it, however is half price than buying individually so I'm kind of skeptical, is Photoshop in this plan the same as the one I'm trying out?
There is no difference in the behavior of the app itself. The single app plan includes more cloud storage and a fancier Typekit plan, but the Creative Cloud Photography Plan is, as you mention, half the price and comes with Lightroom. For most people, therefore, the Photography Plan is far and away the better value. By the by, there's nothing sneaky going on. Adobe introduced a version of the Photography Plan as an introductory offer years ago, and people liked it so much they decided to keep it going.
If you want more info/a comparison chart of what's included in each version, check out this page: Differences between Photoshop and Creative Cloud Photography Programs.
Wow thank you! I'll buy it right away then!
