HP R817 Using Focus Lock, Optimizing Exposure

Using Focus Lock

Focus Lock allows you to focus on a subject that is not in the center of the picture, or to capture action shots more quickly by pre-focusing in the area where the action will occur. You can also use Focus Lock to help achieve focus in low light or low contrast situations.

1.Frame the subject for your picture, or a higher contrast or brighter object, within the focus brackets.

2.Press the Shutter button halfway down to lock the focus and exposure.

3.Continue to hold the Shutter button halfway down while you re-frame or adjust your subject for proper positioning.

4.Press the Shutter button all the way down to take the picture.

Optimizing Exposure

When you press the Shutter button halfway down to auto focus, the camera also measures the light level to set the proper exposure and displays the exposure settings (F- number and shutter speed) in the Image Display. If the camera determines the scene will require a very long exposure, (shaking hand icon) appears. The camera will take the picture, but it will likely be blurry. Try one of the following:

•Set the flash to Auto or Flash On (see page 47) to increase the lighting.
