My job as a portrait photographer is to seduce, amuse and entertain.
But short films are not inferior, just different. I think the short gives a freedom to film-makers. What's appealing is that you don't have as much responsibility for storytelling and plot. They can be more like a portrait, or a poem.
Every time I want to impress someone about samples and hip-hop, I play 'Portrait of Tracy.' It's one of the greatest bass players ever doing a whole composition with only the two harmonics of electric bass; then a three-second loop in it became every great R&B song in five-year intervals.
