Watch Your Colors
The wide angle causes some of the lines in your image to curve. This can cause some distortion in the image. That means that you need to be super careful with the colors in your shot to ensure that the distortion looks good and captures what you wanted to in the shot.
Capture the Crowd
Wide angle lenses are fabulous for taking a shot of a large group of people such as a graduation photo, a wedding photo, or other crowd shots. Look carefully at what is showing in the viewfinder, checking shadows over people’s faces and so forth before checking the shot.
