Table of contents Sample photo Menu search search ISO Sets the luminous sensitivity. 1 [Menu] t [Brightness/Color] t [ISO] t desired setting. (ISO AUTO) 200/400/800/1600/ 3200/6400/12800 Sets the ISO sensitivity automatically. You can set a faster shutter speed, and reduce image blur in dark locations or of moving subjects by increasing ISO sensitivity (select a larger number). Notes • [ISO AUTO] is selected when using the following functions: - [Intelligent Auto] - [Scene Selection] - [Anti Motion Blur] - [Sweep Panorama] • The larger the number, the higher the noise level. • When the exposure mode is set to [Program Auto], [Aperture Priority], [Shutter Priority], and [ISO] is set to [ISO AUTO], ISO is automatically set between ISO 200 and 1600. • The [ISO AUTO] setting is not provided in [Manual Exposure]. If you change the exposure mode to [Manual Exposure] with the [ISO AUTO] setting, it is switched to 200. Set the ISO according to your shooting conditions. z Adjusting ISO Sensitivity (Recommended Exposure Index) ISO setting (speed) is the sensitivity to light of recording media that incorporates an image sensor that receives light. Even when the exposure is the same, images differ depending on the ISO setting. High ISO sensitivity With high ISO sensitivity, images will be captured with an appropriate brightness even under insufficient exposure. However, increasing ISO sensitivity will cause images to become noisy. Low ISO sensitivity You can record smooth images. However, compensation for low ISO sensitivity will be made by slowing down the shutter speed. You should take camera shake or movement of subjects into account, too. Index 68GB
