Way back in the spring of 2011 I did an illustration for Alternatives Journal about how new technologies (such as Print-on-Demand) are revolutionizing the publishing world. Since then, two of my clients have used Print-on-Demand services to create their own books! The first was A Circus Mind, for which I produced an epic dozen illustrations; the second is Inge's project. And that doesn't include the two books I self-published: a slim portfolio book and a series of watercolour cat illustrations I did for various holidays and special occasions.
I ended up using Adobe Illustrator for the illustrations, because a lot of them are more diagrams or technical illustrations than anything else. It was a nice change of pace for me -- I'm such a Photoshop jockey!
Most of my work has been editorial commissions. My first love is editorial, but it is nice to branch out and create stuff that's got a bit more of a shelf-life.
When Inge's book is finished I'll be sure to let you know!
