In this blog post, we'll explore how ND filters can elevate your photos and videos! We’ll also some tips on selecting the right type of filter for your specific needs.

What Are ND Filters?

ND (Neutral Density) filters are often compared to sunglasses for your camera lens. They restrict the amount of light entering your camera without affecting color. This allows you to manipulate exposure while keeping settings like aperture or shutter speed where you want them. Whether you're aiming for silky smooth waterfalls or shallow depth of field under bright sunlight, ND filters give you greater control over the settings you want to use while shooting in different conditons.

Fixed vs. Variable ND Filters

Fixed ND Filters: These filters offer a set level of light reduction, such as 4-stop (ND16) or 10-stop (ND1000) filters. Fixed filters provide exceptional image quality since they use a single piece of glass, minimizing potential issues like vignetting or sharpness loss. However, changing the filter often requires carrying multiple types which can be expensive and cumbersome
Variable ND Filters: Variable ND filters consist of two rotating glass elements that let you adjust the darkness by twisting the front ring. This versatility is ideal for “run-and-gun” filming or dynamic situations where changing light conditions require quick adjustments. The Peter McKinnon Variable ND filters from PolarPro are designed to minimize common problems like vignetting and the dreaded “black X” pattern that some variable filters produce.

Why PolarPro’s PMVND Stands Out

PolarPro’s filters use premium fused quartz glass with a low refractive index, ensuring that image quality is maintained. Unlike cheaper filters that i once bought before i knew the difference these shots wont degrade your lens’s performance! Its the difference between buying high end sunglasses or gas station sunnies. these high-quality filters preserve sharpness and color fidelity, matching the high standards of professional equipment.

The PMVND filters are available in two ranges and these are all i use for video:

2-5 stop: Ideal for most video shooting scenarios.
6-9 stop: Useful for shooting in bright conditions or for creative long exposures in photography.

How to Choose the Right ND Filter

Here’s a simple method to determine which ND filter you need:

Frame Your Shot: Set up your camera with the desired composition.
Adjust ISO and Aperture: Set ISO to its lowest value and aperture to your desired setting.
Check Exposure: If the image is overexposed, gradually increase the shutter speed until exposure is correct. Count the number of steps—every three increments represent one stop of light.
Select the Filter: Use the stop count to select the appropriate ND filter. With a variable ND filter, simply rotate the ring to adjust exposure on the fly.

Creative Uses of ND Filters

ND filters aren’t just for managing exposure—they also open up creative possibilities:

Long Exposure Photography: Use a 6-9 stop filter or a 10-stop fixed filter to capture smooth water, light trails, or to remove crowds from images.
Cinematic Video: Maintain a 1/50 shutter speed for 24fps footage while using a wide aperture in bright conditions.
In-Camera Transitions: Use variable ND filters to create natural fades by adjusting the filter while recording.

Final Thoughts

ND filters are indispensable tools for photographers and videographers who want to elevate their visuals. Whether you're using fixed ND filters for maximum image quality or variable ND filters for convenience, the right choice depends on your style and needs.
