Thanks everyone for the great answers. They give me lots of hope. I probably could have pulled it off with my equipment, and next time I'll at least try instead of passing.
Funny story I had a novice art director say they wanted me to provide files 6x9 foot at 300dpi with no interpolation or upsampling!!! I told em I don't have the Hasselblad 39 MP back, and even if we came up with the $39,000 I don't think it would come close! This was for a trade show image, I didn't get the job.... not sure if anyone got it. Their budget was about $500.!>!>!
Yeah, I'm running into a lot of people like that, too. People on the other side of the process who have not successfully made the transition from print to digital are the worst. The other day someone insisted I needed to provide them with a 1200dpi file for a business card because, "more numbers is better."
And in line with your experience, these tend to be the people either fresh out of college, or with very small budgets.
