Chapter 5: Edit mode

On the far right is a color slider. In the slider, the actual color selected is where the small black arrow appears. You can then adjust

the color to add white or black to it by moving the slider up to add white (for pastels) until it is completely white or move the slider

down to add black (for a richer color) until it is completely black.

Selecting and adjusting colors

To select a color, click on a square in either grid, or on the color palette. You can also drag over the color palette. When you click a

color, or lift your finger off the mouse after dragging, that color appears in the large Color/Solid square and all its numerical

values; Hue, Saturation, Luminosity, as well as Red, Green, Blue, appear in the boxes.

You can also adjust a color by changing the Hue Saturation, and Luminosity numbers. To select a precise color, type in the values

for that color. You can do the same using the Red, Green, Blue values.

Detail tools

Sharpening an image

You can use the Sharpen tool to sharpen an image by enhancing medium and high contrast edges. You can save your options as a

preset for future use.

To sharpen an image using Sharpen tool:

1. In Edit mode, in the Detail group, select Sharpen.

2. Drag the sliders to enhance or fix your image as described below.

3. Do one of the following:

Click Done to apply your changes and close the tool.

Click Cancel to discard all changes and close the tool.

Click Reset to clear your changes and reset to default settings. If you saved your changes, you cannot reset your settings.

Sharpen options

Amount Specifies the amount of sharpening applied by increasing contrast around the edges.

Radius Specifies the number of pixels to adjust around each edge. Higher values increase the number of

sharpened pixels and tend to bring out coarser detail, while lower values reduce the number of

sharpened pixels and tend to bring out finer detail.

Threshold Specifies how different the pixel lightness values within an edge must be before the pixels within the

edge are sharpened. Higher values sharpen only stronger edges but minimize the appearance of noise.

Lower values sharpen both strong and weaker edges, but can increase the appearance of noise. We

recommend you set the threshold to enhance edges while keeping background noise to a minimum.

Threshold

Feathering

Select this option to create smoother transitions between sharpened and unsharpened pixels. If this

option is not selected, you may see lines between pixels that have been sharpened and pixels that have

not been sharpened.

Blurring an image

You can use the Blur tool to apply different kinds of blur to an image, and you can also save your options as a preset for future use.

To blur an image:

1. In Edit mode, in the Detail group, select Blur.

2. In the Blur type drop-down list, select the type of blur to apply.
