When I started out as a practicing illustrator, I used traditional materials, ink, watercolor, scratchboard. It was 1989, the computer was still fairly new, at least for me. I had a Mac but used it only for word processing, page layout, games, and playing around a bit with MacPaint.
My scratchboard work landed me a regular gig with a local weekly paper. The deadlines were fierce and I kept finding scratchboard unwieldy when making last minute revisions. But I liked the look of scratchboard so, instead of switching to another traditional medium, like pen and ink, I switched to the computer to replicate the look of scratchboard using a digital method. I thought the computer would make revisions much easier and quicker, and it did.
So, as my work matured in its early stages, my medium of choice was the computer, specifically vector art.
I eventually switched to Photoshop so I could incorporate texture and create a more hand-made look to my work. Photoshop became my medium of choice for most of my career. It was the medium I used to develop my signature style. But I still enjoyed making vector art now and then, and incorporating it into my process. And each time I had the opportunity to teach students how to use FreeHand and Illustrator, I became more interested in the process, and the graphic look. I had learned a lot about illustration since my early beginnings with vector art, and I found myself wishing I had known then what I knew now (Faces, "Ooh La La").
