Hi all,

 

I'm coming up to an exterior night shoot setup behind a big barn, to be lit largely by industrial floodlights that we will be bringing in ourselves.

I have a few main questions that i'm struggling to find answers to elsewhere:

 

1) What is the relative brightness of a 400w metal halide compared to 400w tungsen or hmi? 

2) Does this change when you use a coloured bulb variety (primarily blue)? Do these coloured bulbs equate roughly to full CTB/CTO or are they more effecty?

3) Is there another way of achieving different colour temps other than with the coloured bulbs (something a little subtler)? Wikipedia tells me that colour temps

of between 2500 and 22000 are possible. 

 

A decent touchstone is the cool tones that Rodrigo Prieto achieved on the streets in Biutiful (attached).. only slightly less cool.

Shooting on 7219 so am keen for a decent punch.

I'll be testing these things out myself of course but it'd be great to get an idea of the best things to test.

 

Thanks in advance!
