Welcome to Steemit! Lot's of photography here.
There are two photography contests, from Jamtaylor, and Juliank.
I suggest Busy,
Steemengine / https://steemengine.net/join?r=476
, Utopian-io, Steemfollower. They give another way of having your posts be more widely seen and evaluated in the very beginning.
Utopian is for programming efforts; Busy, Steemengine, and Steemfollowers are for things in general, like photography.
There is also The Daily Sneak curation group, and Steem Basic Income.
Thank you for the information :)
