Due to the amount of the heat generated, it may also be used with repro lamps to a limited extent. The polarizing film is useful for preventing reflections or glare from occurring in an image or scene as output from a light source interacts with reflective materials around it. When placed between a light source and a transparent or translucent object, the polarizing film can help show the object's photoelasticity.

Q: 8. I'm using a 6" FeelWorld LUT6 monitor bounced off an Ikan Homestream teleprompter. I'm noticing that if the monitor has light colors on it, there is a visible wash-out effect on the image from the Z6 mirrorless camera. I'm wondering if laying a sheet of polarized film, turned to the correct orientation, would mitigate or eliminate what I assume is a spill of light off axis through the beamsplitter glass and then across the lens front element?

A: I believe you need a polarizer filter on you camera lens first and then put a polarizing gel on you monitor that should help alleviate these issues.

Q: 10. What's the functional difference between the 0.3mm and 0.8mm versions? I'll be using this on a 600w Elinchrom strobe.
