Great.

Below are a few basic points of advice re posting (apart from contest-entries) on Steemit.

1. Longer posts are more lucrative than short posts. If you make a post of 10–20 photographs, it's more likely to earn rewards.
2. Include some text to complement the photos. Anything from background info about the subject, to technical details about the camera or the photo, or even anything about your overall technique. As long as you have a fine balance between images and text, you'll get a better response.
3. Ensure the text and photos are formatted properly, so that your post looks attractive and appealing.
4. Be yourself.
5. Be interesting and informative.
6. Create quality content. Steemit is intended to be a platform of quality content. (You will see many insignificant posts with meager content and no quality. Most of those of posts [called “shitposts” by Steemit whale Stellabelle] will earn few rewards and soon pass into oblivion.)
7. Get online and start curating. Read various posts, comment on those posts you find interesting, and upvote those posts. That’s the best way to attract followers.

Hope this helps for now. Good luck, and Full Steem Ahead!
