A friend of mine who is an independent filmmaker and producer has asked me to shoot stills for his next movie (shooting starts at the end of June). The story takes place after closing hours (between 2 and 4AM), so I will be shooting in low light. I can't add my own lighting, and I am going in almost blind on this. I also mu st be like stealthy ninja while on the set so as not to add to the soundtrack being recorded and not to distract the actors and other people on the set. My plan is to dress in slacks because denim likes to made its own noise(s) and wear darker clothing. As far as what I will be shooting with, well, the only things I have at the time of this posting are a Canon EOS Rebel XS, the kit lens, and a telephoto lens. So, do I shoot with a wide aperture and high ISO for a situation like this? I am still learning technicalities, so don't be gentle.
