You’re probably using Adobe products if you’re studying anything related to digital art or design. Adobe Creative Cloud is the industry standard in this space but the entire suite of programs is quite expensive at $70 per month. Thankfully, Adobe has education pricing for students that drops the entire creative suite to $30 per month for the first year. That includes the big programs like Photoshop CC and Illustrator CC along with Lightroom CC, Premiere Pro CC, Adobe XD and more.
After your first year, the monthly cost increases. While not ideal, it’s still more affordable for students than it is for industry professionals. If you’re not tied to Adobe programs, you might also consider Affinity Photo, Designer and Publisher apps from Serif ($70 each for the Mac or Windows versions), which compete with Photoshop, Illustrator and InDesign, respectively.
