Now, when you are shooting, the Quick Control dial will not make any changes to your exposure settings until you press the UNLOCK button underneath the dial (Figure 1.10). Pressing this button will temporarily cancel the lock on the Quick Control dial so you can make changes.

9. ENABLE HIGHLIGHT ALERT The LCD on the back of the camera provides wonderful feedback on image exposure and color quality, but if your screen happens to be set too bright or too dark, then the image you are seeing may be deceptive. When you take a photograph, you usually want to keep detail in the highlight areas and not “blow out” anything. In other words, you don’t want certain areas of your image to be completely white. For example, if you use your flash while photographing a person and the image is overexposed, the light could flood his or her face. One way to prevent this loss of detail is by enabling Highlight Alert.
