It's a common question, especially from new photographers trying to get their business started: "How do I protect my work and promote it at the same time?" We spend some time tackling this question as today's Photo Help Desk topic.
As Jeremy Verinsky points out, there's always some risk when publishing your work on social networks. You can take steps to protect yourself, such as formerly copyrighting your images or using a service such as Digimarc.
But as I see it, the trick for each photographer is finding a balance between protecting their images and creating new ones. Each person has their own comfort level.
