As an action camera user, I recently picked up a set of four filters for my DJI Osmo Action 3. These filters include:
- 1x CPL (Circular Polarizer)
- 1x ND8
- 1x ND16
- 1x ND32
Manufactured by TELESIN, these filters are also compatible with the DJI Osmo Action 4 and the DJI Osmo Action 5 PRO.
Unboxing and Initial Impressions
Upon unboxing, I was impressed by the quality of these filters. Each filter comes well-packaged, with a protective case ensuring they remain scratch-free. Testing them against the light, I found that they effectively reduce glare and enhance image quality.
Understanding the 180-Degree Rule
The 180-degree rule is a fundamental concept in videography. It states that your shutter speed should be approximately double your frame rate for natural motion blur. For example:
- If shooting at 30 FPS, use a 1/60s shutter speed.
- If shooting at 60 FPS, use a 1/120s shutter speed.
Since action cameras typically shoot at high shutter speeds in bright conditions, ND filters help maintain this rule by reducing light exposure.
Why Use ND and CPL Filters?
ND Filters (Neutral Density):
- Used to control light exposure in bright conditions.
- Helps maintain proper shutter speed for smooth motion blur.
- Essential for cinematic footage.
CPL Filters (Circular Polarizer):
- Reduces glare from reflective surfaces (water, windows, etc.).
- Enhances color saturation and contrast.
- Ideal for outdoor shots in bright sunlight.
Pros and Cons
Pros:
- High-quality optics for crystal-clear footage
- Essential for achieving cinematic motion blur
- Reduces glare and enhances colors
- Easy to attach and remove
Cons:
