Blue color compensating filter

The Lee Filters CC40B is a 100x100mm polyester filter designed to absorb red and green light for blue color compensation. It helps photographers achieve precise color balance by reducing excessive blue tones in captured images. The filter fits standard 4x4 inch filter holders used in professional and enthusiast workflows.

For photographers needing blue reduction

This filter suits photographers who require targeted blue color correction during shooting or when balancing mixed lighting conditions. It also supports stacking with other filters for increased absorption control. Photographers who do not need to reduce blue tones or who prefer screw-in circular filters for lens-thread mounting should look at alternative formats.

CC40 density provides measured correction

The CC40 density offers a defined level of color compensation suitable for noticeable blue shifts in typical lighting scenarios. Stacking multiple filters increases absorption for stronger correction when a single filter is insufficient. Very heavy blue casts may require additional filtration beyond what a single CC40 filter or practical stacking combinations can provide.

Questions about this item

What filter holder or matte box accepts the 100x100mm size of this CC40B filter?

Any standard 100mm square filter holder or 4x4" matte box will hold the 100x100mm CC40B polyester filter.

Can I stack this CC40B filter with a color temperature filter on the same holder?

Yes, the design allows stacking multiple filters for increased absorption and precise color balance alongside temperature filters.

Shoot a grey card under your lighting with and without the filter; the filtered frame should show neutral RGB values with reduced blue channel intensity.
