What is the difference between using an ND filter versus 2 polarizers? - Photography. Understanding & Using Polarizing Filters. Polarizing filters can increase color saturation and decrease reflections — and are one of the only lens filters which cannot be replicated using digital photo editing.
They are an indispensable tool that should be in every photographer's camera bag. However, developing an intuition for how a polarizer might impact a photo often requires extensive experimentation. This tutorial aims to accelerate that process by demonstrating how and why polarizing filters can help — and in some cases harm — different types of scenes.
