Hi everybody! This is a very interesting topic and I would like to share a case scenario that is gona happen next week: very similar to Guy's and very challenging so I have some questions and a drawing hoping to give my contribution to this AMAZING forum! So I'm shooting a medium budget short film where the director wants to perform a car chase sequence with some stunt action in THE DESERT: a car will be rear-ended and will lose control, and we want to follow the action from different angles: lateral (to see the car hitting the other), preceding shot and following the chase for few seconds before the accident will happen. we will be filming from a vehicle with the camera hard mounted on a special quick rail rig. I want to give the stunt drivers as much space as possible to perform the action so I am very concerned about how much space I will be able to light up. Consider that I will be shooting with Alexa, Cooke Anamorphic T2.3 (hopefully) and I'm totally willing to push at 1600ASA. Here's my plan considering very carefully the resources I have: 12K Fresnel unit on a Condor as a KEY light. On the same Condor a 4K par for the background. Then another 4K par to light up the end of the street and a 1.2K par with 500' cable run at he other end of the road to have some fill light when the 12K light source will be fading away. So my questions ARE: 1) Would this scheme be roughly enough to light up for 500'-600' at T2.3 and 1600ASA? Can I hope to have more space lit? Less? 2) Do you think that using a powerful helium baloon floating in the middle of the road, plus some 4K par on the ground would give me more space lit? 3) Would you suggest or recommend alternative light sources staying on the same budget order? I want to say thank you very much everybody and I hope to have suggestion soon. I will post some pictures and light readings of this sequence as soon as I finish the show! Guy, David, looking forward to hear your thoughts! C.
