500px (pronounced "five hundred px") is a global online photo-sharing platform that is a subsidiary of Visual China Group. It is based in Toronto, Ontario, Canada. It was co-founded by Oleg Gutsol and Evgeny Tchebotarev on October 31, 2009. Evgeny Tchebotarev started 500px in 2003 on the social blogging website LiveJournal as a hobby, while he completed a business degree at Ryerson University (now Toronto Metropolitan University). Back then, 500 pixels was considered a good size for web display and was therefore the limit placed on photos submitted to the community for review. Once photographers submitted their photos, they were moderated, and only those of high quality would make it past the community's curators and be published on the site. More information...
