Hard to learn, but rewarding. It does the job.

I use Adobe Photoshop to edit graphics for my company, though it isn't my primary job. Multiple people in the marketing team have their own accounts, and use it for things like editing graphics for presentations or emails. As a marketing manager, the software is constantly handy -- it allows me to do everything from create mockups for my projects to tweak headshots of colleagues and customers. I love the flexibility of the tool.
