Originally posted by Sparkle Thanks for the explanation. Does it matter if, as the poster stated , "... I recently did a print job as opposed to creating a photograph. I thought that the client simply wanted a medium which could best be applied to a website rather that a print that the client may be unable to scan or desired a better quality output for such use.
That doesn't matter. Ideally, you should explain to your client exactly what they are paying for and what the allowed usage is. Extra usage may be charged for more or not, depending on the photographer and the relationship with the client.
The business of photography is about selling services and access, not for physical items. You sell a print, that is the client's access to the information that you've created. You sell a license for web usage, that is the client's access to use the information. It really isn't that much different than software or music licensing (they just have better lawyers and the desire to use them).
It's impossible for any of us to say whether it is worth it to the OP to charge for that extra usage.
