DeviantART is the website where I first started to upload my photos back in 2012. This website is very dear to my heart because of the many artists who inspire me and the lovely active community.
I'm also the admin of a group called A-Foggy-Day.
500px is a wonderful website for high quality photos. The webdesign is top notch and their mobile app is very good.
Facebook. I'm not very active on Facebook but I do upload all my latest pictures to my page.
