As a costumer/backstage artist, I normally do not interact with too many reporters, photographers, or camera crews. But, from time to time they find their way back into the shop (because what we do is actually really cool and some people are interested in it!)
Recently I had a lovely interaction with a photographer while working at Virginia Shakespeare Festival. She made the chat and photo taking easy and well integrated into my already scheduled projects so I did not have to rearrange anything.
In my limited experience being interviewed both for papers and television, I have learned they never use all their footage. If you are gracious, make the interviewer laugh, and are genuine with your answers, the editors of the spot will want to make you look good. The interviewer is your friend, as is the photographer. Learn their names, use them when appropriate.
Something I usually do when being interviewed, I show the interviewer something I'm working on and how I am making it do whatever I need it to do. This allows for something besides my face being on camera and allows for some great "behind the scenes" content for the audience.
There is no reason to be anxious when seeing an interview spot on the shop schedule. Smile, be genuine, and if you really just can't allow yourself to be on camera, dress up some mannequins in costumes for the show. Audiences really like a sneak preview of costumes.
