I once again need your advice on how to approach several night scenes that I'll be shooting in a week's time.
The idea is to successfully construct a solid, uniform and believable nighttime ambience for the backgrounds (underexposed deep blue tones) and have dark silhouettes (or partially rimmed subjects) moving against them.
In terms of providing a realistic, feasible reference, I guess I should mention the interior night scenes in Amour.
The ideal result, however, would be something closer to the Skyfall fight scene in concept, but adjusted to the reality of the circumstances in which my story is going to take place (a family home without any big practical screens as backdrops).
In terms of lighting, I was considering using daylight Kinos to construct the soft ambience, as mainly seen in the Amour stills.
However, one possible issue that I might be having has to do with the camera + lens set-up. The MX sensor is notoriously underperforming in low light, and the only way to keep the shadows deep and noise-free is to shoot at ISO 320.
Not only that, but being the space extremely tight we'll have to use a rectilinear 14mm lens at basically all times. Now, the only option I was given is a first generation 14mm Canon USM F2.8. I had a look at some tests, and optimal sharpness is achieved at around f8.
How much light do you reckon I'll need? Are x2 Kinos for ambience + x1 575 HMI + occasional tungsten practicals going to be enough to light the interiors?
Also, on a related note, are any of you guys aware of any way I could potentially battery-power fluorescent light tubes? In my head, it would make sense if a battery unit connectable to this mount existed. However, I can't seem to find anything of sorts on the internet.
Let me know your thoughts, and as always, thank you very much for your time.
