6. Useful Functions for Adjustment

6.1 Highlight/Shadow/Outside of Color Gamut Warnings

This software has warning functions to support the parameter adjustment.

./img/warn_01.jpgWhen you click the ./img/ico_whitealert.jpg button on the toolbar, you can enable each warning.
A warning will be displayed blinking on the preview image.

(1) Enable Highlight warning

./img/warn_02.jpgThe portion where lightness or color is saturated blinks.
The portion where lightness is saturated blinks in black, and the portion where color is saturated blinks in negative color.
This function is convenient for adjusting "exposure bias" and for adjusting "saturation" of color.


(2) Enable Shadow warning

./img/warn_03.jpgThe portion where the lightness is underexposed blinks in white.


(3) Enable Both Highlight/Shadow warning

./img/warn_04.jpgThis feature gives both the highlight warning and shadow warning simultaneously.


(4) Enable Out of Gamut warning

./img/warn_05.jpgThis feature gives a warning for the portion where the color is outside of the color gamut. It means that the saturation in this portion is too much higher.
Please refer to '10.1.6 Color Gamut and Adjustment Outside of Gamut'.


You can customize these warning levels. Please refer to '9.3 Function Setting'.

6.2 Histogram

The menu command [View(V)]-[Histogram(H)] displays the "Histogram" sub-control.


./img/histogram_02.jpg"Histogram" displays a brightness distribution on a picture. You can check which part of the picture
has what kind of brightness. The horizontal axis means brightness (0-255), and the more it goes to the right side, the more the brightness increases. The vertical axis means the number of pixels that corresponds to its brightness. R,G, and B are displayed in each color on a graph, and the place where these overlap is displayed in additive color mixture.

6.2.1 Display of Histogram

The arrow displayed on the gray scale at the bottom has the following meaning.

./img/histogram_04.jpg(1) Contrast center

This indicates a contrast center of tone.

./img/histogram_05.jpg(2) RGB marker

This displays RGB value at the point where the mouse cursor is on. The value corresponds to the brightness position on a graph.
It is very effective to check where a color of a point on a screen is distributed on a histogram.

./img/histogram_07.jpgIn addition, by clicking a graph, you can see each brightness statistic of the RGB.

6.4 How to Use Cloakroom

In the "Taste/parameter" sub-control, there are convenient ways to register and temporarily past and save the development parameters.
6.4.1 Copy Development Parameter

A basic method of operation is described in "7.4 Initialize Development Parameter" and "7.5 Cloakroom of Development Parameter". This function is used to apply the development parameters, which are adjusted and set for one scene, to the other scene.
This is the same function as copying and pasting the development function parameters. This function can apply the development parameters to four scenes simultaneously.

6.4.2 Save Development Parameter Temporarily

The development parameters are determined after having finished adjustment. But it is sometimes necessary to temporarily record the development parameters on the way of adjustment. Because if you have the temporary parameters, you can restart to adjust the parameters from the point where you lost the way, not from the beginning.

6.4.3 Compare Development Parameter

The [Temporary registration] can save not only the development parameters but also developed images, temporarily. When using this feature, you can compare two developed parameters.
The two parameters are temporarily registered And then you can compare the image switching the parameter. We recommend you to use the this function in the Zoom tool mode. Then you can enlarge the portions of the whole image and compare them easily.

*1 When using this function, you need to set the "Maximize Cache" mode. Please refer to ' Enable Cache Preview' for the setting. Please understand that using this function will maximize usage of memory.
