    Why do we need a solar filter for observing solar eclipses?

    A solar filter is crucial for observing a solar eclipse because looking directly at the Sun, even during a partial eclipse, can cause serious and permanent damage to your eyes. The Sun emits a vast amount of energy, including harmful ultraviolet (UV) and infrared (IR) radiation. Staring at the Sun without proper protection can lead to solar retinopathy, a condition where the intense light damages the cells in the retina.

    Marumi solar filter is designed to block out the harmful UV, IR, and visible light, allowing only a safe amount of sunlight to pass through for observation, fully complying ISO 12312-2.


    What is a ND filter, and why should you use it?

    Have you experienced the shutter being released earlier than you expected when shooting under too-bright sunlight, when shooting a highly reflective water surface, etc.?
    Have you also experienced when shooting video, the motion blur is not effective enough to have appeared as you think it as "cinematic" looks?

    "The light volume can be reduced by using ND filter, and you can intentionally control shutter speed and iris value."
    Even if you are not familiar with slower shutter speeds or controlling aperture, the ND filter enables you to capture more artistic photos than usual.

    A Neutral Density (ND) filter allows you to;
    - reduce the amount of light entering into either image sensor or film without affecting the color.
    - maintain appropriate exposure under bright light conditions

    "Neutral" means that there is no effect on the color of your image.
    "Density" means the intensity of the light in exposure.

    The superior ND filter only reduce the amount of light without affecting any impact on image color, contrast or sharpness.
