First I think we'll start up with a few tutorials on how to color your comics in photoshop. Just follow the links below and learn on my friends.
What if you want to start your fledgling comic book company with a recognizable character but don't have the bucks to pay for licensing? Just start looking into all the works already in the Public Domain. "What's that," you ask? That's when a work is old enough to no longer be copyrighted in the U.S. and to get the skinny on Public Domain click here.
Licensing can be a tricky thing. Finding out who has the rights to that character you know would skyrocket you right to the top of the Diamond Comics Distributer's top 100 listisn't always easy especially if the characters original company has been bought or aquisitioned by several other companies. But have no fear with a little detective work it can be done. using the web to sniff out the trail and e-mailing some of the companies involved can often lead you to the right company. Once you've tracked them down ask to speak with someone in the Consumer Product Department or public relations staff. Like I said before this is not a cheap way to go and you could pay 5 digits or more for your uber-license.
You want to know all about copyrighting that new character you just came up with or that book you just wrote. Well your in luck chumply cause here's the link to the United States Copyright Office. So chill sucka!
