I'd signed up for the workshop about collaborating with artists on graphic novels because I assumed that I had some things to learn. My prior experience was working with Gilead on a 4-page comic and putting together a 23-page script for him (as yet undrawn), and since neither of us had ever gone through the process before with anyone else, we just did what made sense to us. You know how screenplays have very specific format requirements that if you don't use, everyone will decide you're a total amateur? Comic books don't have that. It comes down to "work with your artist to figure out how much detail to provide."
The workshop certainly wasn't a total waste. I got some examples of scripting format that are different from what I've used. They gave some structural guidelines and talked about the experience of collaborating. Unfortunately, they didn't have a projector for their slides, so we didn't get to see a chunk of the material. And one of presenters started the day nervously interjecting "Ahhhhhm" into almost every pause, which caused me to think more about that then what he was actually saying. Fortunately, he got better.
All in all, I'm glad I went. And that I only devoted one day to Wordstock, as Sunday was eaten up by another project altogether.
