ISO and White Balance Settings
● The ISO selects the sensitivity of the image sensor and is set by pressing the ISO
button which brings up a menu of numbers from 100 to 6400. 100 or 200 are
typical ISO settings for sunny exteriors. Interiors would likely require a higher
setting like 400 or 800. Try to keep the ISO at no more than 800. Settings higher
than 400-800 introduce visual noise to the picture. Also avoid using the AUTO
function, as it will likely push the ISO past 800 causing a noisy picture.
● White balance is the next thing to set. It can be set a couple of ways: a Quick
White Balance Preset, or a Custom White Balance setting.
○ Quick WB Preset
■ First select the quick control button on the back of the camera & then
select an appropriate preset white balance for the lighting condition
for which you're shooting, using the touch screen.
