What are the differences between circular and linear polarizers?

What are the differences between circular and linear polarizers?

Circular polarizers allow light to pass through in a circular motion, while linear polarizers only allow light waves in one direction.

When should I use a circular polarizer instead of a linear one?

Use a circular polarizer when shooting with autofocus cameras or when you need to reduce glare from reflective surfaces.

Can you explain how each type affects image quality?

Linear polarizers can cause issues with autofocus and metering in some cameras, while circular polarizers maintain image quality and functionality.

Are there specific scenarios where one is better than the other?

Yes, for landscapes and reducing reflections, a circular polarizer is often preferred, while linear polarizers are great for non-autofocus situations.

What about cost differences between the two?

Circular polarizers tend to be more expensive due to their complexity, but the price can vary based on brand and quality.
