Using dVeloper
|
Histogram
and Gamma Tension
The
Histogram looks at your footage and maps out all the values along
a 0-255 tonal scale (where 0 is full black and 255 is full white).
By adjusting any of the three sliders you can adjust the tonal values
that dVeloper will output when rendering. You will notice the histogram
changes when you change your Region of Interest. The white, gray
and black settings correlate directly to the histogram by giving
you the actual numbered tonal values (0-255). These numbers can
also be changed by highlighting and typing. The Gamma Tension correlates
directly with the blue line that runs from left to right, bottom
to top in the histogram. The blue line represents the tonal values
that are being output by dVeloper. If you drag any of the level
sliders in the histogram and watch the blue line as you do so, you
will notice that certain values are being "clipped" and removed
from the output of the video. The Gamma Tension adjuster lets you
bring those values and details back into the image .
