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.

Good stuff

The film arrived in good shape. It was packaged well with good instructions. I actually cut it in half to use with two light boxes that I made from cardboard. Works well.

High quality product

The filter will be used to block strong sun rays during the afternoon in our home office. We are going to 'frame' it to make it mobile to move as needed, rather than place it on the window as the window is large and we think mobility would be more efficient..wish you sold frames - !

I use for Cross Polarizing my lights for years and it's always been great

Hardly any glare reduction

This filter removes at best, 25-30% of the glare. I have used Visual Pursuits filters for 35 years, and they remove almost 100% of glare. Unfortunately, VP appears to be out of business, so I tried the Rosco's. Most Rosco products are excellent, but this one came up severely short. Very disappointing. The polarizing screen search begins anew.

Great purchase!

Although expensive, I found the polarizer filter exactly what I needed. I cut the large sheet in half to cover two LED lights to reduce annoying reflection for an instructional video. It worked perfectly!

Great color neutrality

This is a nice quality, heavyweight filter with excellent color rendering. I did melt/burn one by getting it too close to my led mono head, so now I’m pretty aware of its limitations.

Very clean and consistent gel

Very professional ND gel. We used it to cancel flash reflections. Worked surprisingly well.

Polarizing filter makes rainbows! Garbage!!!

Filter sheet was supposed to reduce glare. All is did was make my coins look like it had a rainbow oil slick all over it. To make matters worse, I ordered it for my 17 inch photo light box and as the sheet was 17X20 and not 17X17, I had to cut it. $60 wasted as they would not accept a piece of junk that obviously had to be cut to fit inside the box. Good thing I spoke with an expert and explained everything to him/her before I ordered it, huh?

Asked by: li
Yes, what Kirk on Staff said. Remember that placement of the filters (and lights that shine through them) is a little complicated, and you have to follow the right procedure of angle and rotation in order for polarization can take place. Google it.

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.
