The first thing that I would do is to read the script at least twice. The first time is to get an idea of what the story is, the second is to note up the margins with sketches or thoughts on each scene.
The next thing I would do is to lay the entire book out on one piece of 11X17 piece of copy paper. Yes, the whole thing. I'm an avid fan of flow so this was the best way for me to figure things out in one place. It'd usually take me about a day to a day and a half to do this.
This is what Wolverine #167 looked like in layout stage:
|Wolverine #167 Layouts|
|Wolverine #167 page 1|
|Wolverine #167 page 2-3|
|Wolverine #167 page 4|
Anyhow, that's a little peek into my process. I'll get more detailed as time progresses and I get a little more seasoned at this blog thing. Until next time....
