The Cokin P Series Light Graduated Blue Filter is a part of the Cokin P Series filter system, designed to enhance skies and provide subtle colour transitions in landscape photography.

Overview:

• Filter Type: Light Graduated Blue Filter
• Series: Cokin P Series (fits with a filter holder and adapter rings)

Key Features:

1. Graduated Effect:

   • The light graduated blue filter transitions from a subtle blue at the top to clear at the bottom. This gradual effect is softer and more nuanced than the whole or medium graduated filters, making it ideal for scenes where you want to gently enhance the sky's color.
   • The light graduation emphasises the sky without making the colour too intense or unnatural. The effect is usually lighter and provides a more delicate touch.

2. Filter Size:

   • The Cokin P Series filters are 84mm wide and are designed to fit a wide range of lenses when paired with the correct adapter ring.
   • This size allows compatibility with lenses ranging from 48mm to 82mm in diameter, as long as the appropriate Cokin adapter ring is used.

3. Creative Usage:

   • The Light Graduated Blue filter is beneficial for enhancing skies in overexposed or washed-out landscape photos, but with an intense colour effect that would be too overwhelming.
   • It creates a natural sky enhancement, providing a slight blue tint, perfect for adding some vibrancy to images with flat or grey skies without overpowering the rest of the scene.

4. Filter Holder:

   • To use the filter, you need the Cokin P-Series Filter Holder. The holder allows you to slide the filter up or down, adjusting the position of the blue gradient relative to the horizon.
   • Moving the filter within the holder gives you precise control over where the effect starts in your frame.

5. Material:

   • The filter is made of resin, a lightweight, durable material, offering good optical clarity without being too heavy or prone to breaking.

How to Use:

1. Attach the Filter Holder: Attach the Cokin P Series filter holder to your lens with the appropriate adapter ring.
2. Insert the Filter: Slide the Light Graduated Blue filter into the holder.
3. Position the Gradient: Adjust the filter's position to match the horizon line so the blue tint only affects the sky and fades out before reaching the ground or the subject.
4. Shoot: Take your shot with the desired effect, and fine-tune exposure settings to balance the scene.

When to Use:

• Subtle Landscape Enhancements: Ideal for lightly enhancing the sky without making it overly vibrant or unnatural. It is great for scenes that need just a touch of colour.
• Grey or Washed-Out Skies: Particularly useful for overcast days or landscapes with less dramatic skies, where you still want a hint of blue in the sky without making it appear too bold.
• Reflected Light: This can also add a faint blue tone to water bodies, creating a soft, harmonious effect when shooting seascapes or lake reflections.

Compatibility:

• It is compatible with the Cokin P Series filter system, which works with various lenses, depending on the adapter ring size used.
