I am not a photographer, but I think signing up on the webpage and following the steemit page will help you connect with people that might be doing similar things or looking for photographers of certain skillsets.

In the "Seek promoters and influencers" section, the curation league lists people who go around connecting and engaging people as demonstrated by the amount of upvotes, comments and posts that they make, as well as the resteems and curation that they do. This will allow your work to be promoted to a wider audience and have people keep you in mind for opportunities when they come up, whether it is a competition or a gig.

That's all I am aware of without being a photographer myself and trying out all those things myself, so hopefully some of it is helpful.
