ISO

In the ISO Menu choose from ISO 50 to ISO 1600 depending on the conditions you want (number of ISO options may vary depending on which model P+ back is used).

In general the higher ISO, the more noise in the image. This means that for optimal image quality, it is a better strategy to have more light in the scene, or adjusting the f-stop on the camera, than just turning to a higher ISO.

When the preferred ISO setting is set press the “Enter” button to confirm the choice (green √ check mark).

Or if you regret the choice and just want to go back to the previous setting (the one with the little dot), select the “Exit” button (the red X).

White Balance

Setting Auto WB will calculate a white balance based on the information in the image. Auto WB is good for most applications.

If you are using a specific lightsource you can choose that option here.

If the camera back is tethered to a computer, and white balance is set from within Capture One it is indicated with the C1 icon in place of the WB indicator on the main screen.

Custom White Balance

Your P+ back allows you to create up to 3 custom white balances.

Custom WB is available when pressing the WB button at the main menu.
