polar_eyes is a cross-polarization filter that makes it easy to eliminate unwanted reflections on the teeth that are caused by the flash. These specular highlights
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).
Moving back and using lens with narrow angle of view can avoid 21 Sep 2009 As I was a commercial artist/photographer 20+ years ago (and I love great cross polarization) I will lay before you the "secrets" of this phenomenal polar_eyes is a cross-polarization filter that makes it easy to eliminate unwanted reflections on the teeth that are caused by the flash. These specular highlights 14 May 2018 Whether you're 3D scanning or just shooting textures, cross polarization is a simple technique to help remove specular highlights and The aim of this study was to assess the influence of a polarizing filter on the accuracy of dental shade matching using digital photography. A comparison was 1 May 2018 Photography using a polarizing filter parallel to the polarization of the light source (parallel polarizers) enhances superficial structures of the skin, 10 Jan 2018 When cross- or parallel-polarisation is applied to photography, images can be generated which aid in visualisation of surface and subsurface Cross-polarization photography is a technique that removes specular reflectance from photographs. Linear polarizer film is placed over a light or flash, and a KEY WORDS: photography, polarised light, cross-polarisation, macrofossils. PHOTOGRAPHY has long played an important part in palaeontological literature in 18 Jan 2021 What is cross polarization and how you can use it in your photography Cross polarization is a technique that uses two polarizing filters – one on 24 May 2011 Cross polarization is a technique that can be used to take photos of clear plastic objects, revealing a range of psychedelic colors in the objects. Color differences (ΔEab) calculated between the parameters recorded with the dental spectrophotometer and polarized photography were below or at the level of 27 Jan 2016 60 degree polarization; also known the “True Cross polarization”, as the polarizers are sharply perpendicular on each other. Fig.9.
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. Circular polarizing filters start with a linear polarization filter.
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 (sometimes written X-pol, in antenna slang) is the polarization orthogonal to the polarization being discussed. For instance, if the fields from an antenna are meant to be horizontally polarized, the cross-polarization in this case is vertical polarization.
Color differences (ΔEab) calculated between the parameters recorded with the dental spectrophotometer and polarized photography were below or at the level of 27 Jan 2016 60 degree polarization; also known the “True Cross polarization”, as the polarizers are sharply perpendicular on each other.

For cross-polarized photography, polarizing filters were adapted to both a Sigma Macro 105-mm lens attached to an SLR Nikon D5300 camera and the built-in flash in a way that the filters were rotated 90 degrees to one another to provide crossed planes of polarization. To understand (a) the effects of labial enamel on tooth color (b) relationship of color data taken by nonpolarized (NP), cross‐polarization photography (CP), and spectrophotometry (SP).
In both cases you need to set the correct tonal curve and endpoints with the help of a Colorchecker card. 2015 CHALLENGE, WEEK 31 OUTDOOR PHOTOGRAPHY – CROSS POLARIZATION MACRO. Posted on 1 August 2015 by Steve Troletti — Leave a reply.

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.

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.
When the orientation of the filters are perpendicular (cross polarization) Light has the ability to create many different types of dramatic effect, though there is none as vivid as cross polarization. It awakens the imagination with its vibrance of colors. Though this technique was popular 20+ years ago, it seems to have been lost in the digital shuffle. This tutorial will walk you through the process and equipment to experiment with cross polarization. Objectives: To understand (a) the effects of labial enamel on tooth color (b) relationship of color data taken by nonpolarized (NP), cross-polarization photography (CP), and spectrophotometry (SP).
