Tonal Correction Effects

Tonal correction effects can be applied from the Edit menu > Tonal Correction and Layer menu > New Correction Layer.

Brightness/Contrast

Adjusts the brightness and contrast of an image.

You can adjust the following settings:

Brightness

Adjusts the brightness of the image.The larger the value, the brighter the image, and the smaller the value, the darker the image.

Contrast

Adjusts the contrast (difference between lights and darks) of the image.The higher the value, the stronger the contrast; the lower the value, the weaker the contrast.

Auto adjust

This option is available when you select Edit menu > Tonal Correction > Brightness/Contrast. It automatically adjusts the brightness and contrast of the selected layer.

Hue/Saturation/Luminosity

Adjusts the hue, saturation, and luminosity based on the HSV color model.

You can adjust the following settings:

Hue

Adjusts the hue of the color (red, green, yellow, etc.).

Saturation

Adjusts the vividness of the colors.Higher values result in more vivid colors.Lower values result in gray washed-out colors.

Luminosity

Adjusts the brightness of the color.Larger values result in brighter colors.Smaller values result in darker colors.

Posterization

Use Posterization to simplify the image into a set number of color levels.Adjust the level of posterization with the Levels setting.You can set between 2 and 20 levels.More levels will result in a smoother effect.

Reverse gradient

Reverse gradient allows you to invert the colors of the image.The inverted values are in RGB (a range from 1–255).

For example, R: 100, G: 255, B: 0 would be inverted to R: 155, G: 0, B: 255.

Level Correction

Level Correction allows you to adjust the contrast of an image, using a histogram as a guide.

You can adjust the following settings in the dialog:

Channel

Selects a channel to adjust the levels.You can choose from RGB, Red, Green, or Blue.

Histogram

This graph displays the volume of the dark areas (left side) and bright areas (right side) as mountain-like peaks.

Shadows

This controls the darkest parts of the image.Drag to the left and right to adjust the brightness of the image.Drag to the left to make the image brighter, or to the right to make it darker.

Midtones

This controls the midtones of the image.When you move the Shadows control point or the Highlights control point, the Midtones control point moves in tandem.You can move the Midtones control point without affecting the Shadows or Highlights control points.Drag to the left to make the image brighter, or to the right to make it darker.

Highlights

This controls the lightest parts of the image.Drag to the left and right to adjust the brightness of the image.Drag to the left to make the image brighter, or to the right to make it darker.

Shadows output

This controls the darkest parts of the image.Drag to the left and right to adjust the brightness of the image.Drag to the left to make the image brighter, or to the right to make it darker.

Highlights output

This controls the brightest parts of the image.Drag to the left and right to adjust the brightness of the image.Drag to the left to make the image brighter, or to the right to make it darker.

Auto adjust

This appears when you select Edit menu > Tonal Correction > Level Correction. It automatically adjusts the colors of the selected layer.

Tone curve

You can use the Tone Curve correction to adjust the contrast of the image.

Channel

Selects a channel to adjust the brightness.You can choose from RGB, Red, Green, and Blue.

Tone curve

This graph adjusts the contrast of the image.The horizontal axis of the graph is the Input value (original brightness), and the vertical axis is the Output value (brightness after setting). Tapping the graph adds control points.You can drag the control points to adjust the color.

This graph displays the volume of the dark areas (left side) and bright areas (right side) as a histogram in the background.Adjust the tone curve while checking the balance of the original image in the histogram.To delete a control point, drag it outside of the graph.

Color balance

Color balance adjusts the color tone of the image by changing the balance of each RGB color.

Color balance

You can adjust the color balance by inputting values or moving the sliders.You can move the sliders left and right to adjust the balance of cyan and red, magenta and green, and yellow and blue.The value of each slider is reflected as you move them.From left to right, the numbers show the current values of Cyan - Red, Magenta - Green, and Yellow - Blue.

Gradient balance

Adjusts the color balance from selected levels: Shadow, Half tone and Highlight. Shadows adjusts the dark areas of the image, Highlights adjusts the light areas of the image, and Half tone adjusts the bright areas in the middle of the image.

The results of each are different even if Color Balance is set to the same value.Changes made to the Shadows, Highlights, or Half tone options are kept when moving on to the next option.You can go back and select the option again to readjust its values.

Keep brightness

Retains the brightness of the image even after adjusting the color balance.

Binarization

Binarization converts the image into black and white.

You can adjust the following settings:

Threshold

Sets the threshold between black and white.Colors darker than the set threshold will be converted to black, while colors brighter than the set threshold will be converted to white.

Leave transparency

Appears when you select Edit menu > Tonal Correction > Binarization. If turned on, the opacity of the original image will be kept.

Gradient map

Each shade in the image is replaced with colors of the selected gradient according to the darkness of the color.You can use this to test color palettes or to add color harmony at the finishing stages of an illustration.

In the Gradient map dialog, you can adjust settings for the gradient set, the gradient colors, and how it is applied based on the existing colors of the image.You can preview the results on the canvas while you adjust the settings.

When you create a gradient map from the Layer menu > New adjustment layer > Gradient map, the gradient map layer will be created above the current layer, and you can edit it later.By default, it will be set to 100% opacity on the Normal blending mode, but you can adjust the blending mode and opacity for a more subtle effect.

For detailed information on editing the gradient colors and settings in the Gradient Map dialog, please see "Gradient dialog".

Color Match

Color Match adjusts the colors of the layer to match the color scheme of a selected image or gradient.You can use this to make subtle changes, or completely change the color scheme of your artwork.

In the Color Match dialog, you can adjust the following settings depending on whether you set it to refer to an image or a gradient.

(1)Source

You can set the source for the new color scheme to Image or Gradient. The relevant settings will appear for the selected source type.When set to Image, you can use the reference image’s color scheme to the image on the canvas.When set to Gradient, you can apply a gradient set to the image, similar to "Gradient map".

(2)Intensity

You can adjust the intensity of the applied colors.The default setting is 100. The lower the value, the less effect the color reference will have.

(3)Maintain brightness

Turn this on if you want to maintain the brightness of the original image, or turn it off if you want the colors to be closer to the referenced image or gradient color.

(4)Image list

A thumbnail list of images you can apply to the canvas.Tap a thumbnail to apply the color scheme.

(5)Select from files

Add an image file to apply as a color match.You can import the following file types: Clip Studio format (.clip), BMP, JPEG, PNG, WebP, TIFF, Targa (.tga), Adobe Photoshop Document (.psd), and Adobe Photoshop Big Document (.psb).

(6)Import from photo library (tablet)

Import an image from your device storage or photo gallery.

(7)Import from camera (tablet)

Tap to launch the camera app.You can take a photo and add it to the thumbnail list.

(8)Delete

Remove an image from the thumbnail list.

(9)Color bar

This is the preview of the selected gradient.Tap the color bar to open the "Gradient dialog" where you can edit the gradient in detail.

(10)Node

The nodes mark each color of the gradient as well as the transition points.You can edit the gradient with the nodes by dragging and dropping horizontally.Drag the node vertically to delete the selected node.Tap the area under the color bar to add a new node.

(11)Gradient settings

Tap to open the "Gradient dialog" where you can edit the gradient in detail.

(12)Gradient set list

Tap to open a drop-down list of gradient sets.Select a gradient set and the gradient list will change..

(13)Gradient list

Gradients registered in the current gradient set are shown in the gradient list.Tap to select a gradient and double-tap to apply the gradient to the color bar.

Unlike "Gradient map", reversing the gradient does not affect the results on the canvas.

(14)Add gradient set from materials

Tap to open the Add gradient set dialog where you can search for gradient set materials.
