When you use the flash, the light from the flash reflects off the dust particles and is sometimes captured in your shot. In the same way, there are always dust particles floating around nearby when you take pictures with your camera.

You may have noticed this at the movies when you look up at the light coming from the movie projector and notice the bright sparks floating around in the beam. There is always a certain amount of dust floating around in the air. įujifilm describes the artifacts as a common photographic problem: 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 spectra, purple fringing or other chromatic aberration. They can also be caused by foreign material within the camera lens. The artifact can result from the backscatter or retroreflection of the light from airborne solid particles, such as dust or pollen, or liquid droplets, especially rain or mist.

Light appears much brighter very near the source due to the inverse-square law, which says light intensity is inversely proportional to the square of the distance from the source. Cases include nighttime and underwater photography, when a bright light source and reflective unfocused particles are near the camera.
