While for many people, Flickr is still the obvious choice for storing and showcasing images online, pros are apparently leaving the service for a host of alternatives.
Recently the guys over at TheNextWeb took a look at 500px -- a site which is said to be luring serious photographers from the Yahoo-owned Flickr.
In the article they looked at why users were leaving Flickr and why 500px seemed to be a destination for serious and pro users
While the full article is well worth a read, the highlights of 500px over Flickr were said to be the more modern style of the site, optional themes, the photography-literate community and the licensing and sales options.
Though there is also the the ability to have an RSS feed of images and link you account to a custom domain, all this comes at a cost. $50 per year compared to the $25 of Flickr. Let us know if you think it's worth it.
