## An ND filter reduces light entering the lens, letting you maintain **correct shutter speed for video and wide apertures for shallow depth of field** in bright outdoor conditions. Without one, you are forced to use unnaturally fast shutter speeds or tiny apertures.

## **Step-by-step for video**

**Step 1:** Set your frame rate and shutter speed using the 180-degree rule. 24fps → 1/50s. 30fps → 1/60s.

**Step 2:** Set your desired aperture for depth of field. f/2.8 for shallow DOF, f/5.6 for moderate.

**Step 3:** Set ISO to its lowest native value (typically 100).

**Step 4:** Check the image — it will be massively overexposed in sunlight with these settings.

**Step 5:** Attach the ND filter and adjust its strength until the exposure looks correct. With a variable ND, rotate the ring. With fixed NDs, try ND8 (3 stops) first, then ND64 (6 stops) for full sunlight.

**Step 6:** Verify the exposure is correct on the histogram — not the LCD, which is hard to read in sunlight.

## **Choosing the right ND strength**

**ND4 (2 stops):** Overcast days. Light shade. Mild reduction.

**ND8 (3 stops):** Partly cloudy. Open shade. Moderate reduction.

**ND16 (4 stops):** Sunny days with wide aperture.

**ND64 (6 stops):** Full bright sunlight at wide aperture. The most commonly needed strength for video.

**Variable ND (ND2-ND32 or ND2-ND400):** Adjustable. One filter covers all conditions. Most convenient for video where lighting changes as you move between sun and shade.

## **Common ND filter mistakes**

**Cross-pattern artifact:** Variable NDs at maximum density produce an X-shaped dark pattern in the image. Never use a variable ND at its maximum setting — stay below 80% of the range.

**Color cast:** Cheap ND filters add a green or magenta tint to the image. Buy quality filters from reputable brands and white balance after attaching the filter.

**Forgetting to remove it:** Going indoors with an ND filter still attached means very dark images. Get in the habit of removing it when moving inside.

**Vignetting on wide angles:** Thick ND filter rings can vignette on lenses wider than 24mm. Use slim-profile filters for wide-angle lenses.

For video work, a variable ND filter is more practical than a set of fixed NDs. You adjust brightness by rotating the ring instead of swapping filters — critical when lighting changes constantly during a shoot.
