Following on from my stock sites post. I sell my images through a couple of online sites, there's redbuble, fine art america and the one I prefer most photo4me that sells your images in various formats. The set up varies from site to site but on photo4me I have a base price of £15 (minimum amount I recieve) then on a percentage scale so if someone buys a large canvas for example I can make £60-£100, it's totally up to you I know some members that have a fixed price of £100 but I believe that makes the smaller sized prints too expensive. Photo4me is a moderated site so your images need to be accepted but so long as there exposed correctly and in focus your ok.
The advantages of these sites over your own website is the amount of traffic they get, there ranked highly by search engines so their keywords will show up before yours. I will discuss why you should have your own web page soon.
Welcome to my blog. My photography is on a tight budget like so many others out there, but through this blog I hope to show that great photographs can be achieved by all.
