    Auto ISO: when is it the best option?

    Auto ISO is not just for beginners. It can be really useful, especially for travel photography, where you might be taking scenic outdoor shots one minute, and dimly lit church interiors the next.

    It keeps the sensitivity at a low setting when lighting is bright enough to avoid camera shake in handheld shooting, to maximise image quality.

    However, under lower lighting levels, the camera will boost the sensitivity by just as much as is necessary to keep shots consistently sharp.

    It removes the need for you to keep adjusting the ISO setting, so you can concentrate on capturing the image, and react quickly to fleeting photo opportunities.

    With many cameras, you can select the minimum shutter speed, as well as the maximum sensitivity setting available in auto ISO.

    For example, you may wish to avoid ultra-high settings of ISO6400. In any case, the highest sensitivity settings often available in the ‘expanded ISO’ range will generally be off-limits.

    Also in Shutter-Priority mode, auto ISO helps to keep the aperture within the limits of the lens. For example, if you select a shutter speed that’s too fast for the lens’s widest aperture in dull lighting conditions, the ISO will be increased automatically.
