Hello Bob.
I think you mean ‘dolly’ down the table. In a ‘trucking’, shot both the subject and the camera move,(truck along with the action) in a ‘dolly’ shot the subject stays still and the camera moves. (dolly in or out on the subject)
I’ve been a cameraman since getting out of the Air Force motion picture camera school in 1962. And yes I use a lot of zooms. I do a lot of 16mm production for television, a lot of it in a ‘documentary’ style. During an interview I always have my hand on the Micro Force. A very slow and suttle move in at the right moment can really bring out the emotion in the scene. It’s risky at times because one doesn’t want to be caught in the ‘middle’ of a zoom , making the editor’s life hell, but I found it’s worth it to take the chance and 95 per cent of the prodcuers/directors I work with agree. Some will say ‘never’. Others let me try to ‘feel’ the situation and use my experience and talent to capture that moment that they are after.
Cheers,
Richard
