Re: Lighting
Night lighting has been discussed before - but in a nutshell, yes.
Not neccesarily darkening in post though - but light the scene so that it LOOKS like night in the monitor, but you can clearly see everything that needs to be seen. On set, it'll likely be quite bright, but the footage should look like night, movie style

DON'T OVEREXPOSE though... you don't want to light it up too brightly, video handles overexposure quite poorly.

Re: Lighting
I have a question about fluorescents. Please forgive me if this has been discussed before. I've done a number of shorts using halogen work lights and homemade diffusers. They have usually been adequate, and are inexpensive to use. But I was in Home Depot the other day and I saw that they have a number of different types of fluorescent bulbs, all with different color temperatures. Like many of you with more time than money, I drool over professional gear while I try and figure out a way to make something myself cheaply, and nearly as effective. Would using a fluorescent fixture, with the color temp of daylight be an effective light source, or would the flicker, or or other complications be more trouble than its worth? Any insights into this would be appreciated. Thanks.

Re: Lighting
James,
You should check out the article on fluorescents in video use at http://www.studio1productions.com/Articles/FL-Lights.htm I just finished shoooting a low-budget indie on the DVX and loved the few shots we did with fluorescents. I plan to incorporate more fluorescents in my future work.

Re: Lighting
Wow, that was exactly what I was hoping to find out. It sounds like a good investment to give something like that a try. Thanks.

Re: Lighting
Another quick question. Anybody know what the color temp of a 500 watt halogen work light is?

Re: Lighting
Nevermind. I guess they are about 3200 degrees. The key is the word "about". Apparently they aren't very accurate and can vary a couple of hundred degrees from bulb to bulb. So that begs the question of how good an idea it is to use them with other light sources. If they are pretty close, and I get a good white balance, should I still be ok?

Re: Lighting
Hi James - I use 500w and 300w worklamps and have found just that - bulbs vary tremendously. You need to find a 'quality' brand who manufacture to close tolerances - I wonder if one exists ? - I match them by eye (and then white balance of course) maybe not perfect , but better than no light at all !!

Re: Lighting
A couple of hundreds of Degrees in the 3000ºK range is quite a lot. That would be much better in the 5500ºK Range, but still quite noticable. Buy some filters and experiment. You might get away with it. (Also, in some shots, it's not a sin to use different coloured lights. Just make sure you know your gear, and you'll be fine).

Re: Lighting
This is where the "art" of cinematography comes into play. In alot of my film and video work, I have often used uncorrected flourescents in my lighting plan. There is no "rule" that says you have to correct out the colorshift. The big thing you have to worry about is flickering, but most balasts operate on a 60 Mhz cycle so as long as you keep your shutter speed on an increment of 60 you should be ok. As a rule, I get as much info about these bulbs as I can ahead of time. The ASC video and film manuals will show you how to adjust for frequencies.

Can you replace the 4 dollar halogen bulbs in a work light with something more precise?

Yes, although my guess is that whoever started this discussion didn't at the time. Sorry.

Re: Lighting
You can always get some #1 photo floods. They put out a very color accurate 3200 but they don't last that long. If you want to make them last longer you can put them on a dimmer while you set up then crank them up when you shoot. I used them when doing still photography. For video work I would get some quarts lights and the proper bulbs from B and H or someone like that.
