Signing your copyright of a portrait, to your commissioning client

[Marcus Lim]

Hi everyone,
I recently met a client who's interested in commissioning a portrait for her family. The thing was, when it came to the part about contract agreements, it came to her that just as my copyrights as an original creator of the would-be portrait, prevent her from making any commercial sale out of the commissioned portrait, she had also wanted to ensure that the portrait wasn't to be used for any other commercial ventures from me.

So she offered to buy my rights to my portrait. What does "buying of my rights" really mean, and what does it entail? What are the possible implications from this selling of my rights from the portrait?

I hope to hear your views on this, and we can all learn from this experience.
Thanks everyone!
