Clearing out haze

If you photograph a lot of haze instead of blue sky, these horizon shots will usually need more depth. You can use the gradient effect to improve your video. Drop the gradient effect on hazy tracks and set the following parameters:

    Angle: 				0
    Inner radius: 0
    Outer radius: 40
    Inner color:  blue 100% alpha
    Outer color:  blue 0% alpha

It is important to set the 0% alpha color to blue even though it is 0% alpha. The color of the outer alpha is still interpolated with the inner color. This is a generally applicable setting for gradient. Some scenes may work better with orange or brown for an evening feel.
