Photo Tips and Information ISO Speed (p. 81) The ISO speed is the numeric representation of the camera's sensitivity to light. The higher the ISO speed, the higher the sensitivity. A high ISO speed allows you to shoot images in dark indoor or outdoor conditions without a flash and also helps prevent blurred images due to camera shake. This is convenient when shooting images in places where flash photography is prohibited. The ISO speed setting makes full use of the available light, resulting in images that convey the feel of the place they were shot. ISO 50 equivalent ISO 400 equivalent. Tip for Using the Self-timer (p. 49) Normally, the camera shakes a little when you press the shutter button. Setting the self-timer to delays the shutter release for two seconds and allows the camera to stop shaking, thus preventing a blurred image. Even better results can be obtained by placing the camera on a stable surface or by using a tripod to shoot. Histogram Function (p. 24) The histogram is a graph that allows you to judge the brightness of the shot image. The greater the bias toward the left in the graph, the darker the image. The greater the bias toward the right, the brighter the image. If the image is too dark, adjust the exposure compensation to a positive value. Similarly, adjust the exposure compensation to a negative value if the image is too bright (p. 78). 154 Appendix Dark Image Balanced Image Bright Image

The histogram is a graph that allows you to judge the
brightness of the shot image. The greater the bias
toward the left in the graph, the darker the image.
The greater the bias toward the right, the brighter the
image. If the image is too dark, adjust the exposure
compensation to a positive value. Similarly, adjust
the exposure compensation to a negative value if the
image is too bright (p. 78).
