The popular photography portfolio website 500px.com has added a new feature - 500px.com Market. I wonder whether they will have more success than Digital Railroad (now defunct) and PhotoShelter (closed their marketplace, but still offers a sales option for subscribers).
Does anyone else have a 500px account? Will you use the market? They pay you $2 for each $2.99 HD digital download (1920x1080 pixels), and 70% on all print sales.
