    Web cam light filter??

    I have just set up a couple of web cams attached to laptops to take pictures of the BSF building work every couple of seconds and upload to our website.

    As you can see from the images, there is a lot of reflected light from the blinds and the top image has a bit of glare.

    Is there anything that we can use to stop this. some kind if light filter maybe??

    Thanks in advance.

    James

    (Ive attached two images just in case you look at the site when there is no reflection...)

    When we did this a few years ago the best solution we came up with was to put a black board around the camera to stop reflections of the room in the glass.
    It wasn't fool proof though, as the sun would still cause visible shadows on the board that showed up in the reflection.

    I doubt you'll be able to find a 'filter' to do this.

    A polarising filter attached to the webcam may help a little bit, but won't eliminate the problem completely.

    As an addition to what abullett mentioned, block out as much light from the room as possible. A solution which may work, would be to use an empty cardboard box big enough for the webcam to fit in, with an open end pressed flush against the window.

    This might be a bit difficult because it is in a teachers classroom. Don't want to completely black out the windows.

    Thought about this but I would need to weather proof them and find a route inside with the cable.

    They're only web cams most building have overhanging roofs anyway so will keep the worst of the wet off.

    Or just put them in a see through plastic bag.

    I can see what your saying but if you look at the image that is titled ScienceBuilding.jpg, there is no overhang from the roof, its straight up. The building where the cameras are located are identical.

    I'm going to try a polarized camera filter and see if that helps.
