RoscoView is a unique two-part window control system for film and television professionals. It consists of wide width polarizing filter installed on windows and a matching camera polarizing filter. The window filter is available in easy-to-handle acrylic panels or in the traditional soft roll form. The camera filter is optical glass. Rotating the camera filter changes the degree of cross polarization on the window where the RoscoView filter is installed. This results in 100% control of exterior brightness as seen through the window. To the naked eye, the ambient light coming into the room or studio is reduced by only one stop.

What RoscoVIEW Does For you:
- You can instantly compensate for changes in the daylight exposure as seen through the windows
- Reduce studio down-time, no more change out of filter, increase shooting time
- Great for areas where it is difficult to re-apply filter regularly
- More economical for larger window surfaces
- Any size window can be accommodated by seaming two or more pieces together
- Rosco VIEW polarizing filters can be mounted in frames or can be incorporated on the RoscoShade system
More Information (FAQs)
Hard panel RoscoView for windows
- RoscoView is a Linear Polarizer.
- Always place the RoscoView side of the panel facing the camera. It should not face the window. Typically, the RoscoView side has a clear protective liner if received directly from Rosco.
- Do not expose RoscoView to rain or use in areas of high humidity where condensation forms on the material. A "wicking" can occur at the edges of the laminate that will discolour it.
- RoscoView Acrylic is available in 4 foot by 8 foot panels.
- RoscoView laminated to acrylic is subject to the same issues acrylic panels are. It can scratch easily and is not as rigid as glass. Larger panels will have some deflection, particularly if they are mounted at an angle as some TV studios do. Acrylic Manufacturers recommend supporting acrylic every 36-39 inches to minimize deflection. (deflection: 1. Any displacement in a body from its static position, or from an established direction or plane, as a result of forces acting on the body. 2. The deformation of a structural member as a result of loads acting on it.)
- Do not use alcohol based cleaners to clean the RoscoView side.
- To clean, dust off the panels before cleaning with liquids. A "Swifter" has worked well in the past. This removes larger debris before wiping, thus reducing the chance of scratching. Be sure to clean both sides of a panel before mounting in place. Be sure the window is clean as well!
- A good glass cleaner should work well for wiping the panels. Watch for residue left from the liquid used, change cleaners if there is streaking. Use a lint free cloth or micro fiber cloth and avoid rubbing hard.
- When RoscoView in placed over a window an anomaly refered to as "quench marks" can be sometimes be seen. These marks are naturally occurring in tempered or heat treated glass but are made more visible by a polarizer. The same effect is seen when looking at car windows with polarized glasses. The effect will change depending on the direction of the sun, the viewing angle or the cloud cover that day.
- When cleaning, moving and placing panels, wear cotton gloves to prevent transfer of fingerprints or dirt from your hands.
- The polarization effect is optimal at 90 degrees to the panel and is effective to approximately 45 degrees off each side of the 90 degrees. The sharper the angle, the more "banding" that can be present. Distance from the window can affect this. You could compare the off angle effect to a car windshield when viewed through a polarizer, the curved sides are different that the center section. The closer the camera to the panel, the more evident the banding. Banding is inherent in the nature of linear Polarization.
- Panels cannot be effectively "butted together" without some evident light leak through the seam. We advise against "butting" to cover large areas or join using an "H" channel of aluminum or acrylic available from Rosco.
- Always have a small sample of RoscoView to examine panels as you are installing them. Be sure that the orientation of the panels remains the same when placing multiple panels. Otherwise, checker boarding will occur.
- When using RoscoView we suggest you test the filter with the camera(s) to be used to evaluate the effect on video assist. Some motion picture camera video assist systems incorporate a Linear Polarizer internally, and when combined with another Linear Polarizer the effect can diminish videotap image quality, usually at the extreme end of the rotation. While no one is likely to use such an extreme adjustment, we advise testing your cameras before hand to determine how to adjust the video tap for best results. On many cameras it is possible for the video tap to be adjusted or exchanged for one that is not affected. This effect is not restricted only to RoscoView; any linear polarizing filter will cause it.
- RoscoView works well when all windows are on a single plane and provides consistent adjustment of the exterior exposure. Should a window be curved, or an off angle window such as a bay be covered with the filter, the effect will be different than that portion of the image plane for which the effect was adjusted.
- Many Teleprompters now use an LCD screen for projecting text onto the glass. LCD screens use Linear Polarizer's. Our tests thus far show no effect on LCD teleprompters when the camera polarizer is mounted on the lens.
Soft roll RoscoView for windows
- RoscoView is a Linear Polarizer.
- Do not expose RoscoView to rain or use in areas of high humidity where condensation forms on the material. A "wicking" can occur at the edges of the laminate that will discolour it.
- Soft RoscoView is available in 56 inch width by 9 feet long rolls.
- Due to its thickness, Soft RoscoView cannot be "squeegeed" onto glass but must be taped or stretched across a frame and attached to the window. Even when stretched, it is too thick to stay flat.
- The use of clear tapes or polycarbonates, if applied to the camera side of RoscoView can generate discernable effects.
- Clear tapes can generate colour "rainbows" on the tape if between the camera and RoscoView. Clear tapes should therefore be applied to the window side of RoscoView so nothing is between the RoscoView window gel and the camera filter. If applying RoscoView to a window by taping the edges, use an opaque tape. If using multiple sheets of RoscoView for larger areas it is recommended the seams be joined on the window side with a tape like "Clear to the Core"®. A slight overlap of 16th of an inch is generally not noticeable and avoids any light leakage with the seam.
- Polycarbonate (Lexan) substrates have a discernable effect when placed between RoscoView and the camera. Only when placed on the window side of RoscoView with no other material towards the camera is there no effect.
- When using RoscoView we suggest you test the filter with the camera(s) to be used to evaluate the effect on video assist. Some motion picture camera video assist systems incorporate a Linear Polarizer internally, and when combined with another Linear Polarizer the effect can diminish videotap image quality, usually at the extreme end of the rotation. While no one is likely to use such an extreme adjustment, we advise testing your cameras before hand to determine how to adjust the video tap for best results. On many cameras it is possible for the video tap to be adjusted or exchanged for one that is not affected. This effect is not restricted only to RoscoView; any linear polarizing filter will cause it.
- Sheets larger than approximately 1 foot square will not lay flat.
- High heat/direct sunlight can cause the material to become wavy and develop "bubbling".
- Sandwiching between acrylic sheets will not keep material flat.
- Do not use alcohol based cleaners to clean RoscoView.
- The edges of Soft RoscoView are sharp and brittle. To avoid tearing we recommend taping the edges with a Rosco supplied nylon tape.
- To clean, dust off before cleaning with liquids. A "Swifter" has worked well in the past. This removes larger debris before wiping, thus reducing the chance of scratching.
- A good glass cleaner should work well for wiping. Watch for residue left from the liquid used, change cleaners if there is streaking. Use a lint free cloth or micro fiber cloth and avoid rubbing hard.
- When RoscoView in placed over a window an anomaly that looks like stress marks can be sometimes be seen. It is similar to the effect when looking at car windows with polarized glasses. The effect will change depending on the direction of the sun or the cloud cover that day. It is caused by various treatments on the glass itself and is visible only when seen through a polarized material.
- RoscoView works well when all windows are on a single plane and provides consistent adjustment of the exterior exposure. Should a window be curved, or an off angle window such as a bay be covered with the filter, the effect will be different than that portion of the image plane for which the effect was adjusted.
- Should colour correction filters on the windows be necessary, apply them to the windows first, and then apply RoscoView over the correction gel. There should be no gel media between the two RoscoView components: camera and window.
- Many Teleprompters now use an LCD screen for projecting text onto the glass. LCD screens use Linear Polarizer's. Our tests thus far show no effect on LCD teleprompters when the camera polarizer is mounted on the lens.
- As with Teleprompters, LCD TV screens use a polarizing filter. Should one of these LCD TV's be used "on camera" when utilizing RoscoView, its image will be affected in the same way as the RoscoView mounted on the windows. Plasma televisions do not incorporate polarizer's and are not affected.
Installing hard panel RoscoView for windows
Always have a small sample of RoscoView to examine panels as you are installing them. Be sure that the orientation of the panels remains the same when placing multiple panels. Otherwise, checker boarding will occur.
When mounting RoscoView Panels on a window, leave a minimum of 1/2 inch spacing between the glass and the RoscoView panel. This limits thermal transfer and allows the panel room to deflect. Leaving a space at the top of the panel will allow air movement, again limiting thermal transfer.
Small spacers could be placed at the bottom of a panel to permit any condensation to collect evaporate before being wicked up into the panel.
Do not use alcohol based cleaners to clean the RoscoView side.
To clean, dust off the panels before cleaning with liquids. A "Swifter" has worked well in the past. This removes larger debris before wiping, thus reducing the chance of scratching. Be sure to clean both sides of a panel before mounting in place.
A good glass cleaner should work well for wiping the panels. Watch for residue left from the liquid used, change cleaners if there is streaking. Use a lint free cloth or micro fiber cloth and avoid rubbing hard.
When cleaning, moving and placing panels, wear cotton gloves to prevent transfer of fingerprints or dirt from your hands.
To hold panels in place, use an aluminum L bracket secured to the mullion with TESA #4965 double sided tape. Ensure that the mullion material is clean and will hold the tape.
Consider how large an area will need to be supported and adjust your bracketing solution accordingly. Multiple panels and a very large area may need heavier brackets and permanent fastening (screws).
Panels cannot be effectively "butted together" without some evident light leak through the seam. We advise against "butting" to cover large areas or join using an "H" channel of aluminum or acrylic available from Rosco.
