I would highly recommend doing these for your photography blogs. 

1. Use available platforms which runs off steem like http://elegance.blue  . It focuses on Art and photography as well. Your content would be very focused within this category and would be best suited for you. 

2. You could start your very own wordpress hosted site and use Steempress as one of your plugin. By using that, you would not only have a dedicated site to showcase your work but also it will automatically post in steemit.   Steempress also provides some support by upvoting good content, its not guaranteed but they are supporting a lot of authors. 

3. You could also use http://share2steem.com and continue publishing your work on Instagram which will then automatically create a post on Steemit each time you post on instagram with the #share2steem 

Within the next few months I'm sure there would be more and more apps which will support various categories for posting and Photography apps would surely be one of these amazing apps. 

Cheers and have a great weekend

You could use steepshot, then edit the post and add more in steemit later.  I also like using Partiko on my phone but I think you can only upload one photo in each post at the moment, but I'm sure that will change soon.

The best platform on Steem right now for posting  "personal" blog style posts like photography (whether of travel/food/art) is ESteem. The @esteemapp account currently holds over 578,000SP which usually rewards content creators around $1.5-$2 per post if curated by the ESteem team. 

However if you don't mind much about the rewards, then SteepShot is definitely the best platform for Photography posts.. It kinda works and looks like Instagram so it's easy to navigate the site and their app. But as what I've noticed lately, only a few people are actually curating on that platform making it kinda disappointing to those who want to get noticed and rewarded too for their efforts.
