I use free stock photos to create photo manipulations. All edits are currently done using a collection of Android apps - primarily Infinite Painter, and Power Director for the videos. It's challenging working on mobile with the limitation of a big finger and a small screen, but I still get better performance out of my phone than my aging computer. Hopefully there's a hardware upgrade in my future that will allow me to make these with greater detail. Are you a photo manipulator or digital illustrator? What's your setup like?
