Hey guys


I'll be shooting a scene with the hpx170+Brevis inside a kitchen completely lit by daylight, (i'll be daylight balanced)

If exposing for the interior, the windows will of course blow out


where can I find ND gels for windows?

And ND+CTO gels?

and also where can I purchase CTB and CTO gels for lights?
 
http://www.filmtools.com/y.html - even on sale. They've got smaller sheets but for windows you'll probably need a roll I'd guess.

For lights just get the sheets or you might like to try to one of the "packs" I picked up one of the larger (50 gels or something) packs and was able to learn alot about how different types of diffusion etc affected the image. These usually have a good variety of CTO/CTB in them as well.
 
awesome buddy. thanks.




Hey how to Tungsten to daylight

and daylight to tungsten filters work?
 
Like technically how do they work or what strengths to use when? I just warm or cool until it looks good :)

Here's some tech info from Rosco - not much on color balance but interesting material none the less. http://www.rosco.com/us/technotes/index.asp

More from GAM - http://www.gamonline.com/catalog/colortheory/index.php

And this article will mind-numbingly learn you how to know exactly what amount of CTO or CTB you need - and is the reason I just guess and keep a bunch of all strengths available.

Good read though. If you really want to get anal about it you're going to need a http://www.bhphotovideo.com/c/shop/904/Lightmeters_Accessories_Color_Temperature.html
 
Thanks guys!

Yeah I was just asking about using tungsten to daylight filters on the camera, ect, instead of geling lights to a certain color temp

I'll read up on those sources

Filters on the camera are really only ever used by film cameras that are shooting a different color temperature film than the color of light that you are shooting in. For example if you are shooting tungsten corrected film and you want to shoot exterior daylight shots then you would add an 85 filter on the camera instead of having to add gels to all the windows or having to change to a daylight stock. The 85 filter will take all the light coming in and make it orange so the film stock thinks its tungsten.

A lot of cinematographers do this whenever the want to keep continuity in their film stock from some of their interiors and exteriors. If you look on American Cinematographer you will see that a lot of DPs like to shoot an entire movie with a tungsten stock, using an 85 filter whenever they are shooting outside.

I have never used a tungsten to daylight filter on a film camera and I have never seen anyone do it. I think there are some out there... maybe an 80A would work like what you would use in regular photography or something but I don't think it is a common practice.

On a video camera they are pretty redundant since you can just change the color temperature on the camera at will and it is pretty much what the filters are made to do.
