Before you can figure out how to make money with your photography online, it would be a good idea to determine what type of photography business you are in.   The photography industry is divided into a few different types :

1.  Service based photography
This is when you provide photos to a client based on what they have asked of you.  This includes commercial photography, weddings, portrature, editorial  photography, and photojournalism.

2.  Product based photography
This is when you make photographs of your own initiative, without input from a client.

3.  Photo related services.
This includes businesses  such as teaching, publishing, graphic design, and retouching.

Figuring out what type of photography business you want to specialize in will help you focus your marketing plan to attract the right customers.
