(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.
(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.
(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
