Using an 80A filter to balance Tungsten to Daylight to keep WB at 5500k

DSLR's from my experience are a lot noisier at 3200k than they are at 5500k.

I am contemplating experimenting with an 80a filter, iso 5500k and tungsten lights(because they are way cheaper than hmis)

Would the light loss from the filter not be worth it or would it give you the ability to shoot cleaner under tungsten light?


Just thought I would throw that out there before I finish checking out at B&H. ahahhhaah

I do this all the time.

It was more important back when the RedOne (before MX) was very picky. I use it now to a degree, since modern sensors are not as picky. Now a days, I typically use an 80C filter. It's the same thing but not as much. It won't make 3200, 5500 but it get's it half way there which means the blue channel isn't starved as much and I don't lose as much light.

I think it's worth it if trying to get rid of blue channel noise in a tungsten environment on a daylight balanced sensor.

Awesome. Thanks Ryan.

I read somewhere that cmos sensors are cleanest at 5000k (4300k for redmx and 3200k for f65) is this true? What is cleanest kelvin temp for a 60D/7D?

I don't know for DSLR's, but for RedMX, I found 5000 was my magic number. Maybe 4300, but I'd always try to get between 4500-5000.

I have been shooting most of my projects at 4800k and just letting my tungstens go warm. I am also shooting cinestyle, so its a fairly desaturated image.
