All of the comicbook clipart I start with for this site is in the Public Domain and has been thoroughly researched for legality.
I'm doing a few Halloween comicbook clipart graphics right now, I thought I'd show you how I work it - some of the processes I use.
The scanned page. I straighten it up if the scan is lopsided.
I have an old version of Photoshop - would love a new version - but alas - it ain't in the budget.
My old Photoshop is still powerful, - a grunty ol' girl like me.
I cut out an interesting panel.
Enhance it - using Levels, Contrast and Brightness, Curves plus others. I may use Blend modes.
White out the text to use for comicbook clipart, tidy it up. Depending on the graphic - sometimes I need to clean up where someone has spilled coffee or drawn on it or ripped it - you get the picture. It's then ready to use as customisable clipart.
If the graphic is interesting - I might draw in missing bits - putting the graphic back together again. I do everything via mouse. (Saving up for a graphics tablet - swoon!)
Time consuming? Can be. A lot of fun? You bet.
I'm thinking about cards - so this might be a good card topper for a teenage/adult male.
...or this one...
Sometimes I think I might make a printable or two :) ... card toppers or something...so I make it print ready...upload to that ethereal cyber space thingamy...write up the post...
So that's the basic lowdown on how I prepare some of this work. :)
