Hi,
I have to shot an action sequence on an outside night.
I want to create something similar to the one described in the photograph below: a zenith base lighting simulating the moonlight.
The director has asked us that the scene has to distill "rhythm and frenzy" so it is imperative to achieve that effect that the action sequences of movies like "Save Private Ryan" or "Gladiator" (Staccato) have while recording the Cowboys running and fighting each other.
The area that we must cover with the light is approximately 300m x 50m.
The camera to be used to record this sequence is an ALEXA MINI at 400 ISO, and to be able to achieve that Staccato effect we will shutter at 22.5o, and the optics used are Hawk C Series with T: 4 diaphragm, the color temperature in camera is 5500K.
To illuminate the scene we have the devices that appear in the photograph above.
• Fireplaces of 10 x 5 meters.
• Each chimney contains 5 HMI lamps of 1250W each.
• All covered by a full gridcloth fabric
• According to the manufacturer, the chimney lamp assembly responds to the photometric curve on the left.
• The crane can reach each device up to a maximum height of about 40 meters.
I want the light generated by the chimneys to be 1 stop below my base exposure. So can anyone tell how many devices i need to cover the area and the height?
Thanks
