I do not wish to know how the polarizer works, but how to make use of it. Specially in a film camera. I have the film Minolta Maxxum 5, and film Maxxum 7. My 28-80 (D) lens has already the UV filter attached to it. My circular polarizer is CRYSTAL-OPTICS 55mm JAPAN. I understand the polarizer is for outdoors/landscape in a bright sunny day, and one of its purposes is to saturate the colors in the photograph. 1 Screw the polarizer on the front of the lens. 2 Frame and focus your subject. 3 Rotate the polarizer (right or left it dosen't matter) until you see the sky turns blue (through the viewfinder). 4 Fire away. Is that right? Please help; I want to make sure I am using it in the right/proper way, and whether I should remove the UV filter or not when using the polarizer. Thanks.
