Before I started my teleprompting business, I was actually a freelance cameraman/editor. I understand what it takes to 'get the shot' as a cameraman, or nail the perfect cut as an editor.
While I no longer shoot or edit, this knowledge has served me well over the years as a teleprompt operator. I have a deep understanding and appreciation for what goes into the TOTAL production. Shooters have occasionally asked my opinion on shots and I'm happy to give it (but only when asked of course).
