Adjusting Brightness and Contrast
(Histogram)
A histogram allows you to see the data concentration at each brightness level of an
image. You can specify the brightest level (highlight) and darkest level (shadow) within an
image, cut the levels and expand the middle of the tonal range of the image.
Adjusting Histogram
(Tone Curve Settings)
Adjust the brightness of an image by selecting the type of graph (tone curve) showing the
balance of tone input and output. You can make fine adjustments to the brightness of a
specific area.
Adjusting Tone Curve
(Final Review)
Make a final check of color adjustments. The final synthesized tone curve and the
histogram derived from the subsequent image processing will be displayed. There are no
settings to make in this screen.
For a color image, select a color in Channel to check either Red, Green, or Blue, or
select Master to check three colors together.
If you place the cursor on the preview image, the portion will be enlarged and its RGB
values (only L when Color Mode is Grayscale) before and after the adjustments will
be displayed.
(Threshold)
Set the boundary (threshold) at which black and white are divided. By adjusting the
threshold level, you can sharpen text in a document or reduce show-through in
newspapers.
