There's always a way to reach an agreement, and that's why we have contracts. When you put a contract on the table, both parties read it, negotiate, say they don't like clause 1, 2 or 4. They change it, negotiate and agree all the time. As long as you work with contracts, there's no problem; people agree. People submit a request to us, we answer it and we write it into the contract. Contracts change; they aren't fixed.
It's obvious to us that we have to own our works. Consider Yousuf Karsh, who photographed the greatest thinkers on the planet and everyone. He was subsequently able to assert copyright because he had retained it, but if you don't have copyright, you can't live off your pension later on when you retire. You have very specific needs, and we respond to them; there's no problem. However, you don't need all rights in order to meet your needs. We need those rights so that we can publish, create an art book later on or something else. You say it's just a picture of a politician.
