The DIVEVOLK Ambient Blue Light Filter is a precision accessory for underwater videographers who use red filters to restore natural colors at depth. Used alone, a powerful video light can create overly warm, reddish patches where it illuminates the subject — a common problem when combining artificial lighting with a red filter. The blue filter corrects this by cooling the color temperature of your SL50 or SL120 light, balancing it against the red filter for a more natural, pleasing result.
The outcome is footage that looks genuinely true-to-life: the red filter restores the blue and green tones of the water column, while the blue light filter prevents the harsh warm cast that would otherwise appear in the artificially lit areas. Used together, they deliver naturally colored underwater video without the need for extensive color grading in post-production.

- Do I need to use the blue filter with a red filter?
- The blue filter is specifically designed to work in combination with a red filter. The red filter restores colors lost in the water column, while the blue filter prevents the artificial warm cast your video light would otherwise create on illuminated subjects. Using them together produces the most balanced, natural-looking results.
- Will this filter work on the SL20?
- No. This blue filter is compatible with the SL50 and SL120 only. The SL20 uses a different filter system — the colour filter wheel.
- At what depth is this filter most effective?
- The blue filter is useful at any depth where you are using a red filter — typically from 3m onwards, where red wavelengths begin to be absorbed by the water. It is most impactful in the 5-20m range where the red filter effect is strongest.
