If you make the kind of visual books I do, they really have to be seen to be understood. I came across these “art book walkthroughs” by Graeme Franks a few days ago. Simple, perfect online advertisements for my kind of books. Here’s the one for Steal Like An Artist and here’s the one for Show Your Work!
I had my six-year-old do (a more hurried & shaky) one in the trailer for Keep Going:
And way back in 2010, I did one for the Newspaper Blackout trailer. I think I used some sort of HD camcorder, but now, of course, you can just use an off-the-shelf iPhone. (And get better quality, too!)
UPDATE: Graeme made one for Keep Going, too!
