Polarizer Polarizing Lens

Polarizer Polarizing Lens
Polarizing light flash?

Hello, I do not know if anyone knows any fancy effects that can be a polarizing gel sheet, placing them in front to flash to polarize the light emitted? I'm used to using polarizing lenses – but not in lights – or combination of them to the case. So basically … is practiced? If so what is useful?

Its used in the search for stress in Plexiglas models of bridges, etc, or even by stretching a transparent plastic bag, the effect is quite surprising. The technique is to put the gel polarization in front of a continuous light source for the plane polarization is to narrow down, then put a polarizing filter on the camera linear polarization with left to right, if you stretch a bag of clear plastic that is under the polarized light through you and see filter chambers receiving an interference pattern of all the colors of the rainbow, where the stresses are. I do not think the effect is so pronounced with a circular polarizer. You can use a linear polarizer in most Digital Slr by ignoring measurement and autofocus and manual, Pentax cameras are well do not use polarized light in any measurement system or auto focus. constructive Engineers use the technique, making models of acrylic bridges, etc., then you can actually see where the efforts in the construction under various loads, can see at a glance how much of the structure is carrying the load and how they change when the load is moved. The effect also works with flash, of course, is only easier to use a continuous light source, even a kind of Anglepoise desk lamp will work, just about the heat in the gel polarization and has an air gap between light and the gel. The gel works only when flat curve if it scatters the light and the polarization effect is reduced or even lost completely. Chris
