Lens flare is one of the problems you will encounter when shooting in bright sunlight. Lens flare will show itself as bright circles on the image (Figure 11.6). Often you will see multiple circles in a line leading from a very bright light source such as the sun.
The flare is a result of the sun bouncing off the multiple pieces of optical glass in the lens and then being reflected back onto the sensor. You can avoid the problem using one of these methods:
- Try to shoot with the sun coming from over your shoulder, not in front of you or in your scene.
- Use a lens shade to block the unwanted light from striking the lens. You don’t have to have the sun in your viewfinder for lens flare to be an issue. All the sunlight has to do is strike the front glass of the lens to make flare happen.
- If you don’t have a lens shade (hood), try using your hand or some other element to block the light.
