I am a current user of flickr coming to 2 years (or already 2 years? can't remember). I am using it to import the photos to my website to display my works. Flickr had given me good user expectation till now but then it is still insuficient I find.
Last night, I just sign up with 500px and I am quite impressed with the features... especially you can sell your images off your account website. The payout is not too bad... $2 profit from a $2.99 digital download and $40 profit from a $199 canvas print order. The best part is unlike stock photography... there is no strict rules what images you can sell and if I am not mistaken, there is no need for model release form required for portrait shots. I also like the fact that they have a mobile version to display your portfolio (something that currently I am not free to do for my website).
I am thinking of shutting down my website (currently doing manual HTML codings) and stop subscribing to flickr pro then migrate to 500px.
Users of 500px, care to share your experience?
