Selling a picture is like selling a book.It takes a lot of time and effort.  The photographer owns the rights to the photo but he can sell the rights or he can sell prints of the picture. This article will help you learn how to sell pictures.

Selling the rights to use the picture is best done by submitting to a stock photo agency. You could sign up and submit all your photos.  In effect the photos are on display in the shop waiting for a client with a requirement.  If the picture fits the requirements, then the buyer can sign up for using the picture.  This can be for a single or specific use, or for use of the photo for a specific length of time. This is one of the best places to sell pictures.

Alternatively, like a book, the picture can be sold as a print.There are several sites that will help you setup a portfolio to sell pictures.  The buyer chooses what size prints he wants and these are sent via courier. 

Or, you could have your own photography site and sell the prints on your own site.  This might be a good idea if he has a sizable portfolio.You would need to do some PR and promote your site and this can take a lot of time to see results.  He can do this via the use of internet marketing and SEO techniques.  This is the hardest part for most photographers, they are great with taking pictures but not so much with promoting those pictures.  This is where it would be wise to hire someone better than you if you can afford it. 

Having your own website where you sell prints would be particularly useful if you have a brick-and-mortar shop or studio.  The website can be a venue for advertising, as well as a source of additional income where he can have his clients order prints instead of going to the studio.  You could use other stock photo sites to start small and then expand from there as more people become aware of your work.  This would be an option for aspiring photos with limited capital.
