Do not sign a model release:

A)  If the photographer and a witness do not sign also.

B)  If you are not provided with a copy of the signed release.

C)  If you are not convinced that the photographer’s work will
represent you in a way that you approve.  This matter
includes the photographer’s choice of potential publishers.

D)  If a model release provided by the photographer seems to
provide protection only for the photographer, not for you.
In this situation, offer your own version of a release as
an alternative.  The sample offered in Appendix D may help.
