Konica Minolta IV instruction manual Tone curve / histogram auto setting

The input shadow slider sets the black level. As the slider is moved to the right, an apparent increase in contrast can be seen in the displayed image. All pixels to the left of the slider are set to 0 and any image detail they may contain will be lost.

The black and white output levels can be adjusted. By moving the output highlight and shadow sliders, the contrast of the image can be reduced.

Click the color-histogram button to view the red, green, and blue histograms.

Click the histogram RGB display button again to close the color histogram display.

Tone curve / histogram auto setting

The auto-setting function automatically adjusts the tone curve and histogram to maximize image contrast and color. The darkest pixels in the image are set to a black level of 0, the brightest pixels are set to a white level of 255, and the rest of the pixels are distributed between them equally.

Click the auto-setting button. The change is immediately reflected in the displayed image. To view the change in the histogram, press the apply button. Click the reset button to cancel the auto setting.
