CPL Filter: Why, When, and How to Use a Circular Polarizer

A CPL filter, or circular polarizer filter, is a popular and powerful filter that can reduce or eliminate glare and reflections from surfaces in your photographs. In this article, we will introduce this filter type and analyze its use and effects.

Unusual Adapter Places a Polarizing Filter Between Lens and Sensor

While originally launched in 2017, Fotodiox created a line of lens adapters for modern and vintage SLR lenses it calls Polar Throttle adapters that have a built-in polarizing filter. The design allows multiple lenses to be adapted to a single mirrorless camera without needing different sized filters.

Cross Polarization: What It Is and Why It Matters

Cross polarization is a technique that uses two polarizing filters - one on the light source and on e on the camera lens - to get rid of unwanted specular reflections.

When and How to Use a Polarizing Filter

Reflections are often unwanted, and glare will wash out an image. Polarizing filters counter the reflective measures and will deepen blues and add contrast to skies, reduce or remove reflections from water and windows, and increase contrast and saturation.

The Magic of Polarizing Lens Filters for Your Camera

Polarizing lens filters help your camera see the world in a new light... literally. If you've never used a polarizing filter before, check out this great 3-minute video by photographer Christopher Frost in which he discusses why these filters are so neat and how to use them.

Filters, Do We Still Need Them?

With the advent of better camera technology and clever processing software, do we really need neutral density filters any more? Can’t we just replicate the effect of filters in Photoshop or even in camera? Isn’t the dynamic range sufficient in my shiny new Sony camera? Well, yes and no…

MagFilter Uses Magnets to Give High-End Compacts Some Filter Love

Compact cameras are becoming pretty serious photography tools when it comes to sensor sizes and lens qualities, but one thing they generally lack is an easy-to-use filter system. Interchangeable-lens photographers can usually just find a filter of the correct diameter and use it with their lens, but things get more complicated when you're dealing with fixed-lens cameras. Although using filters is possible with some models, the systems aren't very friendly: they're usually proprietary, expensive, or based on unwieldy adapters.

That all changes with the new MagFilter by CarrySpeed, an easy-to-use filter system for compact cameras based on magnets rather than threads.
