Tone CURVES/HISTOGRAM | Minolta AF-2820U instruction

TONE CURVES/HISTOGRAM

When the Tone curves/Histogram Correction button is clicked, the Tone Curves and Histogram dialog box is displayed.

The Tone Curves part allows you to change the tone curves and directly correct the output value.

The Histogram part allows you to specify the input and output area from the information included in a film and correct images. Also, this dialog box displays the histogram of the image area inside the cropping frame in each RGB color. The level is indicated in 256 color steps

(0 to 255) from left to right side.

The tone curves and histogram are linked to each other so that when the tone curve is corrected, the histogram is automatically corrected.

Click on in the Image Correction tab.
