Frequently Asked Questions (FAQs)

1. What is the GREY filter?

Neutral grey filters are something like sunglasses for the camera system. The intensity of all wavelengths is more or less evenly dampened. A uniform reduction of the image brightness avoids the overexposure of the scene.

2. Do professional photographers use ND filters?

Professional photographers use filters for both capturing and editing photos. While shooting, many professionals carry UV, polarizing, and neutral density filters to help enhance images in-camera.

3. What is VND filter?

A VND filter is comprised of two circular polarizing layers of glass that are designed to dial in the opposite direction of each other. The inner polarized ND filter is fixed directly onto the lens of your camera, while the outer polarized filter is fitted and rotated with the front frame.

4. What is 3 stop ND filter?

The 3-stop is the preferred ND filter for 90% of wedding and portrait photographers. This will allow you to control shutter speed below the cameras maximum 1/4000 or 1/8000 and lower your shutter speed to control flash sync more effectively. If your camera goes down to ISO 50 then get the 3-stop.
