Im a student and i use the student plan, where i only Photoshop and Lightroom. However I've been surfing the internet looking for an answer;
My question is, can i add more apps only using Illustrator and After Effects on my Creative Cloud Photography plan Student and Teacher Edition Plan. Or, do i really have to buy them individually?
If you have the Photography Plan you can upgrade to a full plan which will allow you to have all four applications plus many more. Otherwise, the student plans are restricted to being as they are defined and to get individual applications would require you to purchase separate full priced subscriptions. Personally I can't see a difference between the Photography Plan for students versus not for students. For the cost you would incur for the Photography Plan and even one other application it makes sense to just go with a full student plan.
