I'm a final year student and currently in the pre-production and planning for our graduation film.
As a result I'd like to ask a few questions and wanted to generally just check back if my plans or approach to certain scenes/looks seems reasonable.
I'm noticing more and more that my knowledge is limited to our uni's kit room, but beyond that I feel like a baby learning to walk.
In terms of this graduation film hat means currently especially the area of HMI and Generator's.
I know an HMI omits 5600K daylight light and is about double (?) as bright as a tungsten bulb, that it is Hydro-oxygen haze, based and requires a ballast. In the practical side of it however I am quite lost.
So jumping to the point: For the film there are some scenes that are set in a warehouse-like location both day and night.
It is a large area and for the mood and atmosphere of the film I was aiming for something similar to this:
My plan to approach this was to use an HMI (2.5K or 4K) to shine though the windows and put a large silk (this is basically large diffusion cloth, correct?) in front of it to fill the windows, as well as add a Haze machine.
Then, after getting that ambient light add any lights for characters, either through diffusion or bounce.
For the night I was thinking of the same setup but with a CTO or CTB in front of the HMI.
CTO to simulate orange streetlamp light and CTB to simulate moon light.
So, first of all: Does that seem like a reasonable approach to achieve that?
Now two problems I have:
The location we're looking at doesn't have enough power outlet so we were thinking of hiring a generator.
And, when it comes to that I am quite clueless. I know generators run off petrol, and are very noisy, so our sound recordist would kill me, so I was wondering if there are any noiseless generators? And in which power levels they come? I reckon we'd need between 10-15 Kw.
Problem number two: The location we're currenly looking at is on a 1st floor, so is it even possible to use that HMI safely? Or would have to scrap that plan and light simply from the inside?
I should probably also mention that I'd be looking for a stop of roughly F4.0, at least for the wides.
And while I'm at it: The location warehouse building has several areas, that are not always shown at once but we may move into, all at the same floor all with windows: Is it possible to use the same HMI through different positions (for different shots obviously)?
Any tips or advice would be greatly appreciated and thank you for your time! :-)
All the very best,
