The filters designated as 81A, 81B, and 81C are classified as warming filters. These filters are designed to enhance the color temperature of the light entering the lens, effectively adding warmth to the image. They do this by allowing more of the warm tones in the spectrum to reach the camera sensor while slightly filtering out some of the cooler tones, which is particularly useful in daylight conditions where the light can appear too chilly or flat.

Warming filters are typically used in portrait photography, landscape photography, or any situation where the photographer wants to infuse a scene with a more inviting and pleasing color palette. The numerical designations (81A, 81B, and 81C) indicate the strength of the warming effect, with 81A providing a subtle warming effect, 81B offering medium warmth, and 81C presenting a stronger warming effect, allowing photographers to choose the right filter based on their specific creative intent. This ensures that the final image captures the desired tone and mood.
