ND'ing a window
Posted 04 April 2011 - 06:46 PM
Is it as simple as cutting a roll of nd to the windows specs and gaffering taping it or attaching it on? would the nd be noticeable within the shot? Are there any good ways to hide it?
appreciate any help

make sure it's flat, though.

Would filtering the light source with a diffuser work you think ?
Sure, provided that you have a big enough net or silk, and a small enough exterior area seen through the window. Bear in mind, too, that the sun will move throughout the day, so that butterfly on high rollers or whatever may need to be tweaked from time to time. The logistics typically favor just ND-ing the window.

Or you can get window treatment thats set-dressed in-shot (blinds, curtains, etc...) - you may be surprised how expensive gelling windows can be.
Now, the more important discussion - what's your end goal? There are a couple ways to go about this and both involve knowing how much stop you need. If you're simply trying to balance the window to your indoor exposure you need to figure out how much of your overall exposure is coming from the window first. Also, figure out what kind of lighting you can afford inside - tungsten, hmi/kino, or bounce. If you're using tungsten units, make sure that instead of just ND you get 85ND gels! Then you're working tungsten indoors. If you're spending that kinda money to gel windows, you probably wanna make the most of that effort and use cheap tungsten lighting (and not worry about gelling practicals). It may be cheaper to rent bigger HMI units inside and skip gelling altogether - with good location scouting you can figure out what time of day to avoid so your lighting units will make the most of what you have.
Or, go old school and ping-pong where possible - using shiny boards, xenon mirrors and diffusion you can redirect light from outside an off-screen window to where you need it.
But before going to any trouble - decide what it is about the window you wanna save - is the action outside important? what time of day is it supposed to be?
