First of all, unless the compensation paid to the photographer is very high, exclusive N.A. print right rights is a lot to ask for. This embargo of 180 days effectively eliminates the opportunity for most secondary licensing. Editorial is traditionally done at a reduced rate because of the potential fo resale. If the resale is eliminated, then up front fee be correspondingly high. Any embargo should be limited to the periodicity of the publication, and should be limited to particular publications that may be in competition with the primary client.
Broad embargoes are simply unfair.
Reprints are a commercial use and should command commercial fees accordingly. To ask for these rights without additional compensation is ludicrous. This value is well beyond the initial editorial fee. In addition, Red Herring seeks the use of material for their own promotion and advertising. Advertising usage commands the highest fees in the industry, and should be negotiated accordingly.
