Lighting Day interiors - Why choosing big fixtures? (3 replies and 1 comment)
I wonder why people chose big fixtures like an 18k or 12k over smaller units to light interiors?
Thanks in advance.
- If you're trying to simulate hard sunlight falling through a medium to large sized window, you need a big light. A small light won't have the spread or intensity.
- If you're trying to simulate soft overcast light through a medium to large sized window, you need a big bounce or diffusion frame, which either needs a big light to fill it or multiple smaller lights.
- If you're trying to light a day interior to a higher f/stop in order to balance with daylight views out the windows because you don't want to cover all the windows with ND gels, then you need either a big light or multiple smaller lights.
- If you're trying to light through windows with the lamp some distance from the window in order to have a less-fast fall-off rate across the room, or to fill a large window corner to corner for a sharp window pattern on the floor or walls, then you need a big light, unless it is a moonlight effect and doesn't need to be very bright. But back it up far enough and you need a big light even for moonlight.
The logic I've be told is one big lamp gets the job done more efficiently and quicker than setting up multiple units. Especially if you're on location, with a cramped space. Turn on the light and the room is lit, which you can direct, shape and bounce as you see fit.
Sometimes in a tight space it is easier to fill a bounce surface or diffusion frame with multiple small units because you don’t have to back them up as far to fill the frame as with one big unit, plus a big unit is, well, bigger.
Thanks a lot for the informative Answer 🙂
