Festival and club photography is the lifeblood of the dance blog-o-sphere. Those moments captured in time, often in a surrealist high-definition, are how people connect and reconnect with the raving experience. Good photography is art, surely, but in the internet age, photographers aren't treated as artists. It's common practice for fans, blogs, media outlets, even performers themselves to blatantly re-appropriate images without crediting the photographers who shot and edited them.
If an individual remixes a song, it goes without saying that they credit the musician who made the original. This is a golden rule of dance music. However, this stringent culture of attribution does not seem to apply to photographers and their work.
