[Threshold Level]

Adjust the threshold by moving the slider

 

or entering a value (0 to 255).

[Reset]

Resets the current setting to the default

 

value.

NOTE

The brightness of color and grayscale images are expressed as a value between 0 and 255 but the brightness of black and white images is expressed in terms of either black or white, including the parts of an image which are a color between the two. The boundary at which black and white is divided is called “threshold”.

●Tone Curve/Threshold Drop-Down List

This drop-down list enables you to save a set of color settings made for the focal cropping frame. If there are no cropping frames, settings for the whole preview area are saved.

You can also recall the saved settings and apply them to the selected frames or the whole preview area.

[Custom]

When this option is selected, specify a value

 

for each color setting. Even after the

 

registered settings are applied, [Custom]

 

resumes automatically if you change any

 

setting or make adjustments to the selected

 

cropping frame.

[Add/Delete]

Opens the [Add/Delete Tone Curve Settings]

 

dialog box ([Add/Delete Threshold Settings]

 

dialog box, when [Black and White] is

 

selected in [Color Mode]). This dialog box

 

enables you to name and register a set of

 

color settings.
