Histogram

The user may perform adjustments to color levels to obtain more realistic images for
observation and analysis.
Color level adjustment means redefining the R/G/B color levels in each channel and then
re-allocating pixel values. Adjust color levels (gradations) to increase or decrease the
range of the selected area in the image, tuning it to brighter or darker values. The user
can also adjust the individual components of the three RGB channels separately to
change the image color via the corresponding channel(s).
Manual Color Level: The user can manually adjust the image's dark tone (left gradation),
gamma. and highlight brightness level (right color gradation) on the histogram to
regulate the image's tones, such as contrast, shading and image layers, to obtain the
correct balance for the whole image.
Auto Color Level: Check [Auto Min] and [Auto Max] to automatically set the brightest
and darkest pixels in each channel to white and black, and proportionally re-allocate
pixel values between them.
