First, you may feel more comfortable discussing your project with the judges if you aren't worrying about what they're thinking of your appearance. They will be concentrating on your project, and so should you.
Second, photographs will be taken at all public events during the Fair. Many of these photographs will be posted to our Web site, and some may even show up in your own hometown newspaper. Photographs will be taken during the judging interviews, the Opening and Orientation sessions, and especially the Awards Ceremony. Take a look at the photographs already posted for previous Fairs. Imagine browsing this site years from now and finding a picture of yourself. What do you want to see?
