Hi, I just found this thread and forum in search of help, for what I believe is radio frequency banding.
I photographed rooftop fireworks, ontop of a 44 story building with many, many antennas and dishes. To my horror after coming home to review the images, most had extreme banding. Can you all confirm this is the case? I'm shooting with a Canon 5D.

Yep. That's what RFI looks like.
Also, does this banding occur with film cameras?
What (in camera) is exactly affected by the radio frequency interference?

No, RFI can't affect a film camera because the image is light all the way to the film, where it's captured as a chemical change.
In a digital camera the RFI would typically affect an amplifier stage such as you find immediately after the sensor. I don't think RF affects a CMOS sensor, but that's a guess. Once the analog picture signal is digitized by the camera's processor it becomes immune to interference.
