Changing the ISO Speed Still Images Movies When the ISO speed setting is [AUTO], it is set automatically to suit the shooting mode and scene. The higher the value the ISO speed is, the greater the light sensitivity is. The lower the value the ISO speed is, the smaller the light sensitivity is. ●●Press the [ ] button, choose [ ] in the menu, and choose the desired option (= 24). ●●The option you configured is now displayed. ●● To view the automatically determined ISO speed when you have set the ISO speed to [AUTO], press the shutter button halfway. ●● Although choosing a lower ISO speed may reduce image graininess, there may be a greater risk of subject and camera shake in some shooting conditions. ●● Choosing a higher ISO speed will increase shutter speed, which may reduce subject and camera shake and increase the flash range. However, shots may look grainy.

Insufficient overall image contrast can also be automatically corrected before shooting to make subjects stand out better. ●●Press the [ ] button, choose [i-Contrast] on the [ ] tab, and then choose [Auto] (=25). ●●Once the setting is complete, [ ] is displayed. ●● Under some shooting conditions, correction may be inaccurate or may cause images to appear grainy. ●● You can also correct existing images (=75).
