Joe, I'm not sure how long you have been doing this, but IME you are wrong here. FWIW at last count-I quit counting a few years ago-I have had over 400 articles published. On nearly every shoot I send out queries to magazines and every year I sell many articles off of cold submissions. They are hungry for input and expect to pay the photographer if selected-HOWEVER when they are getting submittals from architect's PR people they often times assume that the architects own all rights and are offering the images for free to get into the magazine. My contracts are very clear about this because I have had so much experience with it. I have yet to have a story killed because I insisted on use fees, though in some circumstances the architect has antied up to cover the magazines fees because of their misleading pitch. I am not unreasonable or cutthroat about these fees-I have always been paid well upfront for the shoot. But as I tell people "I don't need exposure, I need income".
Defiantly not as long as you, and not as experienced. I am speaking from a little experience and much advice, but I have found that magazines are skimpy, or at least the local ones. On a national level, almost no experience yet, although I am planing on starting to offer a submission service to my clients for a reduced cost, making it up on the publishing fees.
I too am very clear on their use vs. a magazines use in my contracts.
