3.0Basic functions

3.1Setting ISO

ISO functionality is controlled by the back.

The default ISO setting is ISO 50 or 100 depending on the back of the Camera system. A rule of thumb is that the higher ISO you are using, the higher is the degree of noise in the image, though Capture One has a powerful noise reduction.

Depending on the back the Phase One ISO scale is currently 50, 100, 200, 400, 800 OR 100, 200, 400, 800, 1600 using the button on the top left, when in the main menu on the back scroll up and down and press “enter” and the desired ISO is chosen, OR if using tethered mode use the Capture panel in the Capture One application.

ISO and White Balance

When the display is in its home position the two buttons to the left, ISO and WB brings you directly to the ISO and White balance settings, where you can scroll up and down, and select the setting you want with the “Enter” button. Also White Balance can be controlled by Capture One if you are working tethered.
