The photo shows some pieces I've picked up over the years. Getting Started With Cross Polarized Light Polarizer filters can be used to enhance contrast and saturation in landscape photography and reduce reflections or glare on shiny surfaces such as water. 2021-01-30 Cross-polarisation, with regard to visible light, is a process wherein two polarisers with perpendicular orientation to one another are used on the incident and reflected lights. Under 2007-01-06 2019-04-16 2018-12-07 2004-04-01 polar_eyes is a cross-polarization filter that makes it easy to eliminate unwanted reflections on the teeth that are caused by the flash.
I´m using Adobe Lightroom as raw conversion software for a number of different makes of cameras and lenses. Polarization (also polarisation) is a property applying to transverse waves that specifies the geometrical orientation of the oscillations. In a transverse wave, the direction of the oscillation is perpendicular to the direction of motion of the wave. A simple example of a polarized transverse wave is vibrations traveling along a taut string (see image); for example, in a musical instrument Crystals Photographed with Polarization Microscopy: Water, Beer, Caffeine, Vitamins, Amino lamellae and the alignment of the polymer molecules within the lamellae results in birefringence including a Maltese cross. Anyone can do this type of photography if they have access to a light microscope, some polarizers, and a method to Back in the day, I would use cross polarization when doing high end fine art copy work. Using a dozen high power Lowell tungsten lights, a better light scan back on a Toyota 4×5, art ( oil painting originals, sometimes VERY large ) tacked up on a wall.
Learn how to give ordinary cheap plastic a psychedelic look with cross polarizer effect I work as photographer at an art museum and I use cross-polarization all the time. Yes, it increases contrast and saturation, but that's no more "correct" or "incorrect" than working without filtration.

Think of light as wooden ice-cream sticks that are flying towards a set of bars. The bars will only let the sticks that happen to be aligned with the bars through, and absorbs all the other sticks. Cross Polarization is actually a scientific application that finds weaknesses in glass and plastic.
It works by using a light source with light polarized in one direction, and then using a polarizer on your lens to filter the polarized light in the opposite direction. Cross polarization photography lets you differentiate between regular glare and back scattered light. The back scattered light is the complextion within the skin. Both the camera lens and the flash have a filter placed in front of them. Geekery and science meets photography: Cross-polarization is a fantastic little technique that exploits a quirk in the way polarizers work. Think of light as wooden ice-cream sticks that are flying towards a set of bars.

Linear polarizer film is placed over a light or flash, and a polarizer filter is likewise placed on the camera lens. When cross- or parallel-polarisation is applied to photography, images can be generated which aid in visualisation of surface and subsurface elements. Improved access to equipment and education has The equipment pictured includes a 35mm format camera, 180mm macro lens, 72mm circular polarizing filter, a 550 EX and a 420 EX flash with polarizing film taped in place over the flash head. The flash units are supported by Wimberley flash brackets consisting of a module 1 (quick release arm SS-010) and a module 4 (macro extension arm SS-040). In "Cross Polarization" you are essentially aligning all the light waves coming off of your light source and into your camera are matched to each other and the extra light reflections, glare, hot spots are eliminated.
