Practicals

Does it matter what kind of bulbs you use for practicals? For night scenes? Day? Wattage? Should I use 3200k?

I'm mainly trying to light the inside of a house well enough to shoot from the outside through a window. Thanks.
 
Night is easy, ust use tungsten and light up the exterior of the house to match.

Day time is harder. You can tent the outside and light it that way, or perhaps shoot at magic hour and fill the inside with daylight kinos and HMIs.

You should also try to use a linear polo to cut thru the reflections.
 
coming from still photography, i'm curious why you'd use a linear polorizer instead of circular? i thought the whole point was that auto focus is preserved (which some people don't like to use, of course, but still i dont see how a circular would hurt)
 
You can buy bulbs that fit in stardard household light sockets in both daylight and tungsten. This you probably already know... Whether to use one or the other depends on your shot, time of day and what your trying to accomplish.
During daylight hours, I have often changed the bulbs in household practicals to match daylight, simply to bring up the overall brightness or because it was important for my shot at that given time. Sometimes I like the warm glow of a warmer tungsten bulb mixed with the available daylight, to establish mood or just believability. I often find that i'm either replacing tungsten with smaller wattage bulbs, or adding a dimmer to the mix, because a standard 60-75-or even 100 watt bulb, simply "blows out "all detail in the lamp shades, and is 5-6 stops hotter than my talent. I just use 40 watt or sometimes smaller bulbs to keep the lamp from overpowering the scene. If you really need to use the practical to light up your talent, you should experiment with different types of wattages and color temp of different bulbs to see what you like best.
If your shooting outdoors at night, and you want to show the indoors through the window. You can add a few lights in the room, hidden from camera, and use tungsten lights for this. If you must show the interior from outside during the day, you will need daylight bulbs, and high wattages of them as well.

You don't need circular to preserve autofocus capability on video cameras. It's a problem that's unique to SLR cameras.
 
I carry a full case of household practicals everything from 7.5w to 150w in both clear and frosted types and a couple of photofloods (500w). Lower wattages are great when the lamp is in shot and you don't want it to blow out and the higher wattages to boost room ambience and for use in chinaballs, etc.

Generally you can get away with practicals going warm so colour temp is not that huge of a factor. If you have to dim a practical a lot it's better just to change to a lower bulb.

I also carry some PAR bulbs with household base that I screw into custom sockets I made. With a little bit of blackwrap they can make nice accent lights, etc.
