Ah, a fellow photographer! Willkommen bei steemit! You're gonna want to check out Hive account@appics if you haven't already, they're kind of an instagram-like app for mobile. But I say that not because it's a cesspool like Instagram. I say it because it's a slick, simple UI that makes interacting with the Steem Blockchain much easier. Also, there's lots of great photographers and models on there.

I'm on the dev team with Hive account@vimm, a live streaming site. I usually start streaming long after midnight in Germany, but we got a couple awesome German streamers on there. Check out Hive account@bembelmaniac, Hive account@nerdtopiade, Hive account@kanrat, and the Hive account@helpie-caster community. Lots of really cool people.

I see Hive account@partiko replied to you. They're a good front end for mobile devices, and they have a private DM system built in. Definitely worth checking out.

I gave you an upvote to help you get started, a resteem for the awesome vine reference, and a follow because I look forward to your photography. If you have any questions, feel free to ask me. This place can be a jungle, especially if you're new.
