You can use the Threshold effect to create a black and white image. You can save your options as a preset for future use.
To apply the Threshold effect:
- In Edit mode, in the Add group, click Special Effect.
- Click Threshold.
- On the Threshold tab, set the options as described below.
- Do one of the following:
- Click Done to accept your changes and close the pane.
- Click Cancel to discard your changes and close the pane.
This slider determines which pixels become black and which ones become white in the black and white image. Any pixels that are brighter than the selected threshold will become white and any pixels that are darker than the threshold will become black.
