If you work for a company, you likely have little-to-no control over the work you create. The company generally owns the copyright on anything and everything you do. But if you’re a freelancer, it’s a whole different ballgame.
I’m not a lawyer, nor do I play one on TV; so I don’t want to go down the copyright rabbit hole here. That being said, I have found a nifty service that can help you with legal copyright issues you may run into. Check out Binded: Copyright made simple.
In a nutshell, Binded allows you to upload your creative work upon creation, creating a permanent record of copyright ownership. At this point, that’s all the service is. But according to their site, they plan on doing a whole lot more—including the ability to officially register your copyright. Take a look at their FAQ page for more details.
Binded seems like a pretty cool service for creatives, particularly photographers and graphic designers.
