AfterShot Pro 3 Color Tools

The AfterShot Pro 3 Color tools are located in the second panel on the right side of the screen.  

In most cases, all you'll need to adjust an image will be the Basic tool but on occasion the color tools may be needed.

The components of the Color panel provide access to five different color correction adjustments.

The five components are ...

  1. Curves/Levels.
  2. Color Correction.
  3. Color Balance.
  4. White Balance.
  5. Color Management.

The AfterShot Pro 3 Color tools are not used in isolation.  As you start working with the color Tools you'll find yourself going back to the Standard tools for the basic adjustments.

AfterShot Pro 3 Color Tools

Curves

The Curves section is a combination of the Standard Curves and Standard Levels tools that are found in most digital editing programs.

Apply Curves - enable or disable Curves.

RGB - select RGB or individual color channels.

Before/After - switches Histogram from before and after views.

Left White Arrow - point A - Sets the input point (255).  Dragging this point down moves the Histogram left, making the image darker.

Bottom Black Arrow - point B - Sets the input black point (0).  Dragging the arrow up moves the Histogram to the right making the image lighter.

Right White Arrow - sets the output to 255 (white).  Drag the arrow left to lighten the image and be careful of clipping.

Left Black Arrow - sets the output to 0 (Black).  Moving this point to the right darkens shadows and going too far will clip the blacks.

Bottom Grey Arrow - sets the middle grey (128) point.  Dragging the arrow right lightens the mid tones and dragging left darkens the mid tones.

Curve - click on any point and drag up or down.  The classical "S" curve to incr4ase contrast can be set.

Auto Contrast - click the button to set the white and black points based on the image information.  This is similar to Auto Level in the Basic adjustments with the added feature that the levels can be adjusted.

Point Tools - black, white and grey.  Click the black, white or grey tool in the image to set the point to the color of the tool.

Reset Arrows - the first is Reset All and restores the Curve to flat.  The second is Reset Current and resets the current curve.

Here's a link that demonstrates some of the different adjustments in the Curves Section.


Color Correction

This is the Color Correction panel - not very big but powerful!

The top colorful row and the row underneath it (all white) are the color wells.

The four adjustments below the color wells are ...

Hue - change the Hue of the selected color.

Saturation - from -100 (color removed) to +100 (totally saturated.

Luminance - from -100 t0 =100

Range - the greater the range, the more pixels of a similar color will be included.



Color Balance

This section of the AfterShot Pro 3 Color panel allows you to fine tune the colors in your image using the following controls ...

Cyan/Red - Magenta/Green - Yellow/Blue - shifts the colors along one or all of the axis.

Saturation - mutes colors producing a pastel look when the slider is moved to the left and produces more intense color when moved to the right.

Vibrance - a subtler version of saturation.

Hue - changes the colors in the image by the about on the slider.

HSL/HSV - choose either Hue/Saturation/Lightness or Hue/Saturation/Value color spaces.


White Balance

NOTE:  White Balance can only be modified on a RAW file!

White Balance includes three presets - As Shot,Click White and Custom Kelvin setting.

White Balance Preset - they are sunny, shady, tungsten and flash.

Click White - select the little dropper tool and click on a part of the image that should be white.

Temp - if you know the Kelvin temperature of the scene or simply experiment using the scroll wheel,

Tint - allows you to fine tune the white balance.


Color Management

This tool controls the color management mode applied to the active version.

Color Mgmt — enables color management when set to an ICC profile. Switching this to None-Linear still applies color management, but leaves the image in a linear color space.

Custom Input Profile — advanced users can choose to create an input profile from the linear data associated with a camera profile.

The AfterShot Pro 3 Color Tools are a powerful suite of adjustments.  Open some difficult images and give the adjustments a try.
