Rosco 7300 Overview

This Rosco Polarizing #7300 Filter is a neutralizing linear polarizing film used in front of lights to reduce the glare caused by smooth surfaces such as glass, water, paper, and certain metallic objects.

This sheet is especially effective when used in conjunction with a polarizing filter at the lens (cross-polarization). It should be placed at a slight distance from hot lights.

question

Can I cut this down to fit a Nikon R200 flash?
Asked by: Anonymous
Yes, but remember, you need a pola filter with the camera.

question

Does the cross polarization work with flash units? Studio speed lights? I want to photograph guns but I need to neutralize the glare on hi gloss finishes and the spectral highlights on shiny metal finishes. Would cross polarization work for that?
Asked by: Dan S.
I've gotten cross-polarization to work wonderfully when photographing 2D items (like museum paintings). The reduction/elimination of glare has been stunning. I've never attempted to light something with more dimension (like a gun).

question

Are these fire-resistant?
Asked by: John
I doubt it's fire resistant. Ask Roscoe for it's melting & ignition temp. Roscoe is a high priced, high quality co. So far as I can remember they have very good customer service. I wouldn't use it or any other plastic type filter too close to a hot light. (Too close, say, <3) Hot light meaning a light such as a tungsten or halogen continuous flood light. Way further away for a spotlight. I doubt that strobe modeling lights would melt or catch them on fire. Measure the temp @ the distance U intend to to use the Roscoe filter to see if it exceeds Roscoe's recommendation. If need be, buy a larger filter to use @ a > distance. Don't forget that if you are using this type of polarizing filters, over the light source, they must be perfectly aligned w/ each other. I forget if they must be used w/ linear or circular lens polizers. I have to laugh when I worked in a commercial studio how many plastic type defusers I saw w/ patches pinned in place from hot lights burning holes in them.jdmcgraw

question

When shooting artwork such as oil paintings should I use a circular polarizer or a linear polarizer on the camera lens in conjunction with the Rosco polarizing gels on the lights?
Asked by: James
I'm using a Micro-NIKKOR 60mm f/2.8G Lens with a circular polarizing filter and it works fine. Just make sure the gels in front of the lights run in the same direction.

question

How does one support polarizing sheets in front of strobe. I have cut them up to fit my 7x7 reflectors but they tend to warp and yellow from the heat. I have supports for the 18x18 purchased, but they are no longer effective after 10 years and do not know where to find them.
Asked by: chris a.
There are a couple of solutions:1. Lowell makes gel holders that hold the gels a safe distance away from the floods if you are using their DP floods2. If not, I made window mats (out of regular mat board that picture framers use) and mounted the gels between two of them, using glue to hold the matboards together, and tape to secure the gel between the two window mats. That way, I could then use clamps that held the now- framed gels to a light stand that I could place at any distance from the light. My gels have lasted now about 4 years.

question

@null...I want to buy there gel polarizers for shooting artwork but I would like to use led lights. Do you think that LED lights are good for shooting art?
Asked by: Girino U.
I find best art color is obtained with Solux halogen 4700K. But they are not bright. And some polarizing gels are not optically uniform. Do a gray card test shot to be sure it's adequate for you.

question

What temperature should the filter not exceed, or what is the highest temperature I can let the filter get to from a direct light source before it starts being damaged?
Asked by: Anonymous
I can't give you and exact temperature but I would guess that if you can't hold your hand at the same spot as the filter for more than a few seconds it is too hot. I use LED's now so this in not a concern for me anymore. However, for many years I used a filter similar to this one in front of 650 watt tungsten lights at a distance of about 12-14 inches from the face of these open-face lights. They did not melt but did fade considerably over time.
