2. Installation
To install the Kenko 82mm Red Enhancer No.1 filter:
- Ensure your camera lens has an 82mm filter thread. This information is usually printed on the front of your lens or in its manual.
- Carefully align the filter's threads with the threads on the front of your lens.
- Gently rotate the filter clockwise until it is securely attached. Avoid overtightening.
- To remove, rotate the filter counter-clockwise until it detaches from the lens.
3. Usage Guidelines
This filter is designed to enhance red tones, making colors like those of cherry blossoms, autumn leaves, and sunsets appear more vibrant when shooting with color reversal film. The effect is subtle but noticeable, enriching the warm hues in your photographs.
Important Note: As stated previously, this filter is specifically for color reversal film. Using it with digital cameras will likely produce undesirable color casts, typically a strong greenish tint, due to how digital sensors process color information compared to film.

4. Care and Maintenance
Proper care ensures the longevity and performance of your filter.
- Cleaning: Use a soft, lint-free microfiber cloth specifically designed for optics. For stubborn smudges, apply a small amount of lens cleaning solution to the cloth, not directly to the filter.
- Storage: Store the filter in its protective case when not in use to prevent scratches and dust accumulation. Keep it in a dry, cool place away from direct sunlight and extreme temperatures.
- Handling: Always handle the filter by its edges to avoid leaving fingerprints on the glass surface.
5. Troubleshooting
If you encounter issues with your Kenko Red Enhancer No.1 filter, consider the following:
- Undesirable Color Cast (e.g., greenish tint): This is almost always due to using the filter with a digital camera. The filter is designed for color reversal film only. For digital photography, consider in-camera white balance adjustments or post-processing for color enhancement.
- Difficulty Attaching/Removing: Ensure the filter threads are clean and free of debris. Do not force the filter. If it's stuck, try using a rubber filter wrench for better grip.
- Image Softness or Flare: Ensure the filter surface is clean and free of smudges or dust. Excessive flare can sometimes occur with filters in strong light sources; consider using a lens hood.
