Kippertie IR Spectrum

[Scott Lamoreaux]

Hi guys - I'm new to IR film/photo so please excuse my dumb questions but now that I have received my Kippertie IR Spectrum OLPF, how do I achieve footage that looks like the following?

Straight from the camera, I'm getting a magenta image that looks like this:

(the above was taken on an overcast day shot at 23.98 1/48 5600k 800 ISO)

You need another filter in front of the lens since you're using the Full Spectrum IR OLPF.

I'm using the IR Spectrum not the full spectrum

How are the example frames they show achieved?

Buy a stronger IR filter or just use channel mixer or lower the saturation...that's it Scott.

You have to make post adjustments, you know that right?

Use the white balance tool.

Then adjust levels to taste.

The first image is black and white (saturation 0%) with lots of contrast added. They might have also used a polarizer to get the skies that dark, check if your polarizer works with the OLPF, mine does, but my ND does not.

lol of course I was more asking how to achieve an end result like the example image. Overcast day won't yield the dark skies I'm looking for.

which polarizer do you recommend for matte boxes? Or circular for canon glass

I use a 138mm tru pola from Schneider. I'm not sure if polarizers care about wavelength, but the tru-pola definitely works great in infrared.

Remember only the sky at a 90 degree angle from the sun is strongly affected by a polarizer (the entire horizon at noon, straight above at sunset/sunrise, etc).

Does anyone know if MOTION MOUNT works on controlling the exposure with IR spectrum?
