After which I draw a rough version of the drawings with cool-erase blue-red-green and then ink it using either a ball point pen or a g-pilot pent.
After I am done inking the lines I erase the red pencil lines.
I do the rendering in Prismacolor black... it's a colored pencil but very soft.
Then I scan in the pages in grayscale and open Photoshop.
I place the images in the page and turn the layers to multiply to see through.
I adjust my panels to the correct size. they are drawn with the object too, set to multiply and have a drop shadow.
I use the panels to mask the drawings by selecting them from the path menu and then loading the selection tool and applying a mask.
After that I merge the drawings in one layer, they get back to normal opacity so I have to set it back to multiply, throw an overlay of brown and apply to the drawings' layer.
But fundamentally the page is done :D
I hope this answers some of your questions!
