Introduction
The Cokin P122 Blue Graduated B1 Filter is designed to enhance the sky in your photographs, particularly in dull, flat, or hazy conditions. This filter features a hard-edge transition, making it ideal for landscapes with a defined horizon line. It is part of the Cokin P-Series filter system and is manufactured from C39 optical resin, offering up to 1 2/3-stops of light reduction.

Setup
- Attach Filter Holder: Securely attach your Cokin P-Series filter holder to your camera lens using the appropriate adapter ring (sold separately). Ensure the holder is firmly seated and aligned.
- Insert Filter: Gently slide the Cokin P122 filter into one of the slots of the P-Series filter holder. The filter should slide smoothly without excessive force.
- Position Filter: Adjust the filter vertically within the holder to align the graduated blue area with the sky in your composition. For landscapes with a clear horizon, position the hard-edge transition line precisely at the horizon.
Operating
The Cokin P122 filter is designed to selectively add blue color and density to the upper portion of your image, typically the sky, while leaving the foreground unaffected. This helps to balance exposure and enhance color saturation in the sky.
- Composition: Frame your shot, paying attention to the horizon line.
- Filter Adjustment: Slide the filter up or down in the holder until the transition line of the gradient aligns with your horizon. For scenes without a distinct horizon, you can experiment with the placement to achieve a desired effect.
- Exposure: The filter reduces light by 1 2/3-stops in the blue area. Your camera's light meter should compensate for this, but it's always recommended to review your exposure and histogram after taking a shot, especially in challenging lighting conditions.
- Creative Use: While primarily for skies, the filter can be rotated to apply the gradient effect from other directions (e.g., to enhance water or create unique artistic effects).

Maintenance
Proper care and maintenance will extend the life and performance of your Cokin P122 filter.
- Cleaning: Use a soft, lint-free microfiber cloth specifically designed for optical surfaces. For stubborn smudges, a small amount of lens cleaning fluid can be applied to the cloth (not directly to the filter). Avoid abrasive materials or harsh chemicals.
- Handling: Always hold the filter by its edges to avoid leaving fingerprints on the optical surface.
- Storage: Store the filter in its protective case or a dedicated filter pouch when not in use. Keep it away from dust, moisture, and extreme temperatures.
- Inspection: Periodically inspect the filter for any scratches, cracks, or signs of wear that might affect its performance.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Uneven or harsh gradient transition | Filter not aligned with horizon; too close to wide-angle lens. | Adjust filter position carefully. For very wide-angle lenses, a soft-edge graduated filter might be more suitable. |
| Dust or smudges visible in image | Dirty filter surface. | Clean the filter thoroughly using appropriate lens cleaning methods. |
| Vignetting (dark corners) | Filter holder or filter too close to lens, especially with wide-angle lenses. | Ensure filter holder is correctly mounted. Consider using a wider filter system if persistent. |
