The red filter effectively restores warmth to your shots by compensating for the loss of red wavelengths, enhancing the color accuracy of coral reefs and marine life. In contrast, the magenta filter is particularly useful in greenish waters, helping to balance color tones and simulate the natural hues that are often lost. Utilizing these filters enables photographers to capture the breathtaking beauty of underwater scenes with greater clarity and realism, creating vivid images that reflect the true colors of the ocean.
