When it comes to balancing light intensity in a scene, a Colour-Grad Neutral Density filter can be a useful tool. These filters are designed to have a smooth transition between a coloured section and a clear section, allowing for a more balanced exposure. This is particularly helpful when trying to capture both sky and foreground detail in outdoor photography.

For best results, a Colour-Grad ND.6-to-clear filter is often recommended. This filter has a neutral grey appearance, which helps to drop the exposure and prevent over-exposure in the sky while properly exposing the foreground. This allows for a more balanced and natural-looking photograph. Overall, Colour-Grad Neutral Density filters are a valuable addition to any photographer's kit, providing greater control over light and exposure in outdoor settings.
