Proper formatting when writing for artists
I'm attempting to transition from writing traditionally to writing for comics and I'm new to this so would appreciate any help and advice. I've written many stories but this is a first for me.
Is there a specific format that artists prefer that makes illustrating the words easier?
Is there a different format in general for writing comics as opposed to short or long form stories that helps in any way.
I heard Robert kirkman writes his stories with a three panel layout in mind and am curious what this means.
If there are any questions that are important that I just can't think of I would appreciate any of those to add into the pile.
