bad analysis results.
5) If necessary, reset the whole equalizer (optional)
⇒ Click
(the Reset fine-tuning results button) or select the Profile | Reset Fine-Tuning
Results menu item.
6) Repeat steps 1-5 with other uniform image areas of different brightness
To make a device noise profile more accurate you have to fine-tune it using several uniform areas1 of
the image (naturally, analyzing the same area many times makes little sense). Try to choose uniform
areas to cover all brightness ranges in all channels of the equalizer (i.e., to get shadings on all sliders’
values). Use color shadings as well as red markings (which are used to reflect the range of the current
selection; like –40%) to guide the process of fine-tuning. Also use the color indicators on the bottom of
the Fine-Tuning Analyzer box as guidance when doing that. If the majority of sliders’ values have
green shadings, you can stop the process.
7) Set remaining sliders at your option (optional)
If not set by the Fine-Tuning Analyzer, the sliders of the equalizer have default values. You can leave
them with default values or can adjust these sliders to bring them into better agreement with the
neighbor measured ones.
⇒ Set the remaining sliders as you consider necessary.
Manually adjusted sliders receive the ‘manual’ status (a yellow shading, like +175%).
or
Use Auto Complete to automatically adjust the unmeasured sliders by interpolation based on the
measured data. Click
(the Auto Complete button) or select the Profile | Auto
Complete menu item to automatically complete the fine-tuning.
Using Auto Complete is highly advisable as the last step of the manual fine-tuning process.
The figure below summarizes the status marking of sliders:
When using the noise profile equalizer, use the color indicator to simplify the fine-tuning process.
Colored lines of the indicator show:
• which sliders of the equalizer correspond to the colors of the selected image area/pixel
(press the Shift key for pixel-wise indication);
• which slider values are different from their default values;
• which sliders have (possibly) incorrect values.
The figure below explains each state of the indicator elements:
