Thus, the ideal set-up for "controlled flash use" in macro photography could be something like the image to the left: Flash mounted on a flexible arm (: homemade and very easy to do) with a mounting head that can be rotated. 2004-04-01 · Figure 1 – Moist, soft bodied creatures are prone to multiple bright highlights from flash photography. Here an Upland Chorus Frog is shown without and with the cross-polarization flash technique employed. A circular polarizer is generally only used on the camera lens and is comprised of multiple pieces of glass which allows you to rotate it around to change the polarization. A linear polarizer is one piece of film or glass and you'd have to rotate it manually to change the polarization effect. Cross-polarization photography is a technique that removes specular reflectance from photographs. Linear polarizer film is placed over a light or flash, and a polarizer filter is likewise placed on the camera lens.

Cross polarization photography

In macro photography, we often have the advantage of controlling all of the light falling on our scene, and when that is the case there is a powerful tool at our disposal - cross-polarization. The cross-polarization technique requires that all of the light we are adding to our scene is polarized, and polarized in exactly the same orientation.

Equipment used: one Relio² 4000K, a smartphone and our rotatable polarizer with a linear polarization film inside. That’s all you need.

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 The author investigated the use of cross-polarisation for day-to-day practice after a request from a clinician to remove specular highlights from intra-oral photographs. The paper evaluates camera and light source devices for image capture using cross-polarisation. Following this it defines ways to calibrate the camera to the correct white balance. Yes. Both of these filters exclude light that doesn't match the appropriate direction of polarization.

Both the camera lens and the flash have a filter placed in front of them.
