First off welcome to Steemit.. It's an awesome place. As you're into photography you may want to look at things like Steepshot and busy. They are apps that link to your steemit account and make posting a lot easier. Another key thing is kep your passwords safe. Once you have logged in on your master password get your active, memo, posting keys and log out then log back in on your posting key. You'll only need the active key for selling your steem. I keep my master key backed up by having it written down and hidden. If you're always logging in on your master key you are placing your account at risk. As you are in to photography there are great tags to use that aren't listed like #sevendaysoutside and #walkwithme where photographers share their content. You may want to give them a look to see if any of the content appeals. Their are great folks under those tags and they all tend to be a pretty supportive lot. Well best of luck on your Steemit journey.
