Applying digital filters to photos, particularly photos taken using a phone, is extremely popular. You can achieve many effects in modern software that previously required photographers to use a physical filter in front of the camera's lens.

However, this doesn't mean you should dismiss the use of physical filters. Some effects can't be replicated in software. And even if the effect can be duplicated, it still won't give quite the same result. In this article we'll look at some creative reasons why you should give physical filters a try.

Cross Polarization Photography

without comments

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. 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.

By doing this very little direct light from the polarized light source gets through to the camera's sensor. However, stresses in the plastic object modify the light, meaning it is no longer polarized in the same direction as the polarized light source. This creates the fantastic colors.
