Rod (optics) - In cryptozoology, ufology, and outdoor photography, rods (sometimes known as skyfish or solar entities ) are elongated artifacts produced by cameras that inadvertently capture several of a flying insect s wingbeats.

In Diagram B, the faces of particles illuminated by the flash do not face the lens and therefore remain un-recorded. In Diagram A, the faces of particles directly aligned with the camera's lens are illuminated by the flash, and thus the camera will more likely record orbs. A strobe flash, which distances the flash from the lens, eliminates the artifacts.Д«elow are two diagrams of a hypothetical underwater instance. In underwater conditions, particles such as sand or small sea life close to the lens, invisible to the diver, reflect light from the flash causing the orb artifact in the image. With rain droplets, an image may capture light passing through the droplet creating a small rainbow effect. The image artifacts usually appear as either white or semi-transparent circles, though may also occur with whole or partial color spectrums, purple fringing or other chromatic aberration. The orb artifact can result from retroreflection of light off solid particles (e.g., dust, pollen), liquid particles (water droplets, especially rain) or other foreign material within the camera lens. The artifacts are especially common with compact or ultra-compact cameras, where the short distance between the lens and the built-in flash decreases the angle of light reflection to the lens, directly illuminating the aspect of the particles facing the lens and increasing the camera's ability to capture the light reflected off normally sub-visible particles. Orb artifact are captured during low-light instances where the camera's flash is used, such as at night or underwater вЂ“ or where a bright light source is near the camera.
