I'm just going to upload things that I think may interest you as they arise.
As I've just finished The Owl's very own magazine, I thought I'd share something of the processes of putting the mag together. You may think all the images come from a big Marvel database (they do have an image library but it's nowhere near good enough for our purposes - I think it has 3 or 4 dodgy pics of the Owl).
We did order the Cover image directly from Marvel, but this takes forward planning so I mainly just reserve that service for cover images that I know I'll need. The ordering process can take up to 2-3 weeks.
So we do a bit of research and compile a list of all the characters appearances (and buy as many as we can) - I think The Owl had about 70 appearance (not all useable!)
So you can imagine it was difficult to find a large full page image of the meanie for the intro page! I found this Pin-up by Gene Colan from Daredevil Annual 1 (DD Masterwork Vol.3).
Firstly I scanned the page at 800dpi and isolated the black line art (fairly easy to do using channels in Photoshop) creating a layer of just black. Then I went about removing the bits I didn't want (the lettering and captions) and carefully filling in the tree where I'd removed the box, plus extending the tree on the left (to allow for the shape of our magazine and the text area that goes over the artwork).
