What Is Art?

I recently attempted to enter several 20 x 30 inch prints (framed) into an art competition and after explaining to the director of the art competition that I was submitting "Giclee" prints that I had framed, I was told that they would be accepted.

When I arrived to drop off the art, I was told that this was NOT art because it was a print on canvas. I explained that these are known as Giclee prints and some are hanging in the MFA in Boston. Having started my art career sitting in a field and letting flies and mosquitoes add texture to my painting while the wind blew dust over the wet canvas to compound the problem, you can see that I was insulted. The "director" (if that is what she wants to call herself) refused to acknowledge that these painting/giclee prints were in fact art, so here's the question:

What is art? The fact that you photograph or scan your painting and then reproduce it onto canvas as a Giclee print make it any less art? I always thought this made them Limited Edition Prints. Should she have allowed me to enter them into the competition or should she have stated that they were not allowed at the beginning when I first contact them.
