Pricing of Photo's

[Kel]

Hi Everyone

After the last two drafts I have done I have had people emailing me to buy my photo's as I worked out what it cost me to get them print and add a bit more onto it. As I have set my prices at 5x7 - $8 - 8x10 - $15 and 10x15- $30 and a disc for $50, as I have just started out selling them. But my question is have I set the price to low and what is a fair price for a email copy of a photo? As I did not want to over charge for what skill level is. Any thoughts or comments on this would be every much helpful as I never had to price my photos before.

Thanks

Kel
