Filter Reviews

1 Use together with a Neutral or Circular Polarizer (160 164). Depending on the rotation of the Polarizer, you can vary the colors gradually from one extreme to the other. For instance, the red/blue goes from red through every shade of purple to blue.

2 If you have rotated the Polarizer (160 164) (with the Vari-Colour) to achieve a hue between the two colors of the filter, then when you turn the filter holder as a whole, that hue will not change but reflections will alternate between the two colors.

3 If you have already rotated the Vari-Colour and Polarizer (160 164 ) filters for maximum saturation in one or the other color, you can make reflections disappear by rotating the filter holder.

4 Using the Cokin Vari-Colour without the Polarizer (160 164 ), you can color reflecting areas in either color of the filter depending on the filter position, With filter No. 173, for example, the color will be either blue or yellow. The rest of the image will retain the color of the filter itself.

Helpful hints : The effect of the Diffuser filter 083 is minimal and works well for landscape photography, especially when used with Cokin Graduated, Speed, Super Speed or Multi-Image filters. Diffuser No. 084 is more suited for portraits and still life's. For even greater diffusion effects, use the two filters together. Diffusion filters often collect light from outside the image area that can mislead the camera meter and cause it to underexpose. Long focal-length lenses require less diffusion than short ones to achieve the same visual effect
