Funny, I was talking to photo consultant who began his career as a gaffer in Hollywood. After doing that for a while, he began assisting; first shoot was an architectural shoot. He said he showed up, look at the lighting equipment they were going to use and said "is this it?"
Reminds me of a shoot I assisted on many years ago in Boston. I was hired by an out of town photographer for a celebrity portrait shoot on an active movie set. The shot was to make a fake magazine cover that was going to be used in the movie. The photographer apparently was more of a unit still shooter so was used to working with the set lighting provided and didn't seem to know how to light the rather large room with really high ceilings. He kept trying to light the space all morning to no avail.
After hours of wasting our time he consulted the gaffer on the movie and came back with a bunch of crazy and unrealistic suggestions for lighting the room that would have taken a large crew, many lights hanging from scaffolding inside and outside the building, etc. to achieve. I laughed as there was no way I could do all that by myself, not to mention we only had a handful of strobes
At the time I had been regularly assisting for an architectural photographer, so I finally suggested that I do the lighting, applied what I had learned from the other photographer and saved the day.
Of course the celebrity talent showed up hours late and then only allowed us to shoot 12 frames and left LOL
