Do you have images or films that are sitting on your file servers and nobody, except for your team and the client, knows you did them? Even if you don't, you will eventually have a few some day. How would you handle such requests to not publish images and can you take any advantage of that?
As photographers and filmmakers we take pleasure in producing quality content so that the world may see it came out of our hands. Sometimes a client has a peculiar request to not allow you to put those results in your portfolio, which means a full control over the publicity of the images. Do they have the right to ask for that? Of course, it's a normal part of the contract between you and the client whether it's written or verbal. We, as content producers, get more clients from showing our work. If we were in the financial area we would boast with our bank accounts showing how successful we were, but in the visual world we display visuals, not wallets. If clients demand us to not publish our work the world outside will think we are not producing any new work. For that reason we have to be compensated somehow, and the most obvious way is by asking for an extra fee for agreeing with client's request although it's not good for our portfolio.
If you decide on applying that kind of policy to your business, it is important to educate your clients before any agreement. It should be clear if they do not want the results published in your portfolio. If that's the case, they should know about the compensation that has to be paid. If you don't ask them or you don't have any formal agreement, they have the moral and business right to ask you not to publish the content in your portfolio for some reason.
Do you agree with that policy? If not, what do you do?
