Yosemite is well-known for its beautiful waterfalls, and many people come to the park in summer to see and take pictures of the shining and colourful rainbows. Though not all may realise that they can see a rainbow even at night in Yosemite! Moonbows, or lunar rainbows, are rare natural phenomena that can be seen at the park waterfalls in spring and early summer. They are similar to rainbows, but created by moonlight instead of direct sunlight, and at they are best during the full moon.

What distinguishes moonbows from regular rainbows?
Moonbows are formed by moonlight’s reflection, refraction, and dispersion, while rainbows are created by sunlight’s reflection, refraction, and dispersion. Compared to rainbows, they are dimmer and less colorful, often appearing as a whitish or grayish arc. Moonbows are rarer and harder to sight, relying on specific environmental conditions and timing.

Is it possible to use a regular camera to photograph moonbows?
It is indeed possible to photograph Moonbows with a regular camera, but the task may not be easily achievable. Low light photographic capabilities and a tripod to remain steady will be required to capture the moonbow and its slight intensity, which may require exposure time ranging between 20 and 40 seconds. After capturing the image, you may use post-processing software to enhance its details, but nothing beats the feeling of experiencing a moonbow with your own eyes. Show more
