White Balance and WB Bracketing
The EOS 10D enables accurate overall color balance in most lighting conditions through a number of white balance (WB) options. One auto white balance mode and five preset white balance modes provide optimum settings for commonly encountered shooting situations. Precise dialing-in of color temperature in Kelvin values is also possible, with settings selectable from 2800K to 10000K in 100K increments.
White balance bracketing lets you capture three JPEG images (normal, reddish, bluish) with one shot, and at the same exposure level, with white balance shifted in ±3 stops in whole-stop increments.
Auto and Manual ISO Speeds
When shooting in a Basic Zone mode (Full Auto, Landscape, Close-up, Night Portriat, or Flash-off), ISO speed is automatically set between 100 and 400 in 1/3-stop increments to suit the shooting conditions. Users can also choose Portrait mode (ISO 100), Sports mode (ISO 400) or Creative Zone mode, which allows manual setting of ISO speed to 100, 200, 400, 800, 1600 or 3200 by way of an ISO speed button on the camera's top panel that has been added for easier operation. When utilizing the built-in flash, ISO speed is automatically set to 100 in backlit conditions or 200 in dark conditions.
