Figure 4 – The dots in the lens reflection are an artifact of .jpeg compression.
In Figure 4, the lens reflection is caused by the lower light. To prove that an “object” is a lens reflection, draw a straight line between the light source and the “object.” The line will pass directly over the center of the photo. In addition, the distance between the center of the photo and the light source will be the same as the distance between the center of the photo and the “object.”
In the nutshell, a lens reflection is caused when there is a light source that is captured by the camera lens. Many times it is the sun, but it can also be just a light bulb. That light ricochets, for lack of a better word, inside the camera lens and the result is a lens reflection. The little dots you see are artifacts of .jpeg compression. They can also be an artifact created by LED arrays or collections of light sources from one light device. The shape of the camera sensor and iris, along with the angle of the lens to the light source, is what will determine what the lens reflection looks like. That is why you can use the same camera, but you can get two different images. All lens reflection cases should show a disposition of IFO – Natural Phenomenon.
Lens reflection, also called lens flare comes in many sizes, shapes and colors.
