Only you will know whether the rainbow was really there.
A keen photographer is always on the hunt for new and exciting images. Some of these images may be fleeting moments of nature's beauty: a lightning strike or a rainbow after a downpour. But what if the moment's not perfect? Camera filters exist that allow you to add a rainbow even where none exists in nature itself. These filters consist of a clear piece of glass with a "rainbow" effect applied. A rainbow filter can be a fun addition to your kit, and is easily used in the field.
Instructions
1. Focus on your desired subject. The filter may interfere with your camera's focus mechanism, so get a clear shot before you attach the filter.
2. Mount your filter holder (the housing into which your filter will be inserted). Screw the filter holder securely over the front of your lens. If you have screw-on filters such as a lens protector or UV filter, apply the filter holder over these.
3. Insert the rainbow filter into your filter holder right-side up (with the "rainbow" effect curving upward as it would in nature).
4. Calculate the light level. Be careful not to overexpose the area to which you want the "rainbow" effect applied.
5. Frame your shot. Rainbow filters work best in a wide-angle shot, with the "rainbow" portion of the filter set against a portion of background sky.
6. Shoot the picture. Try several shots, experimenting with framing and light levels.
7. Remove the rainbow filter from the filter holder. Unscrew the filter holder and return both pieces of equipment to your kit.
