Layers & Masking.

Layers and masking are great ways to selectively edit your images, whether it be through using different enhancements on separate layers or masking certain areas of your photos to enhance.

Brush Tool (B).

The Brush tool is a powerful painting tool. It works like a traditional drawing tool by applying the effect in a selected area by painting it in. Use the brush tool to selectively adjust your image. Click and hold your mouse and drag the brush on the area of the image that you want to be affected.

Erase Mask (E).

The Erase Mask allows you to remove an effect that has been applied to the image. Use the Erase Mask to selectively edit your image. Click and hold your mouse and drag the brush over the area of the image you want the effect to be removed from.

Mask Controls.

Clear: Selecting this button will clear the mask you have created.
Invert: After you paint the area that you want to affect with your edit you can easily select the “Invert” button to invert your mask.
Show: Selecting the show button will show the mask you have created in red.

Brush Controls.

The Size slider: Controls the size of the brush in pixels. Use large size brushes for editing large areas of an image and use smaller size brushes for detail work.

The Opacity slider: Controls the strength at which the brush is painting. At an opacity of 100, the brush will apply the effect at 100%.

The Softness slider: Controls the edge of the brush. A softness of 0 will produce a hard edge line when brushing, and a softness of 100 will have a feathered or a transition edge when brushing.

Gradient Tool.

Click and drag the center point of the Gradient Tool to position it and drag the top or bottom lines to adjust for the top and lower gradients. Change the Exposure for example and press the Apply button to place the effect on the image.

The Gradient tool and mask can be altered using the Angle and Opacity controls. The Angle option will precisely rotate the gradient mask to the angle which you desire. The Opacity control will control the maximum amount of the effect applied.

When the Opacity control is set to 100, the gradient will transition from a full effect to no effect. When the Opacity control is set to anything less than 100, the gradient will transition from a partial effect to no effect.

The Histogram and Layers Panel.

The Histogram Panel displays the Zone system where 0 indicates, in hashmarks, the areas that are totally black without any detail all the way to 10 which will display the areas which are totally white without any detail.

Clicking on the upper left button will show in blue the areas that are black or Zone 0. Clicking on the upper right button will show in red the areas that are white or Zone 10.

The Layers Controls.

Layers are a great way to organize your editing activities en route to creating, or “building up” the best image possible. It’s also very handy for exploring new directions for your images.

The Layers panel provides the ability to add multiple effects to your image. Every image will have a single layer to begin but can have up to 8 layers in Tonality CK (5 in the standard version). Each layer that is added can have a separate effect, opacity and mask.

The Add New Layer (plus icon) and Remove Layer (subtraction icon) buttons will allow you to add new layers for new effects or to delete layer effects.

Each layer has a visibility control (the eye icon) to turn on and off the effect of that layer on the whole image. Each layer also has an Opacity slider which controls the overall strength of the effect applied to your image. The Opacity slider in the Layers panel is the same slider that is available at the bottom of the Adjustment Tools, so making an adjustment to one will be reflected on the other.

Each layer mask will have an icon that will reflect any selective controls such as a gradient or brush, to apply the effect selectively to the image. Any part of the Layer Mask icon that is white will have the full effect applied, any part of the Layer Mask icon black will have none of the effect applied, and values of gray will have some of the effect applied.

Right click on a Layer to reveal even more options. Among the most important of these is the Create Luminosity Mask feature. These are layer masks that are created from specific tones in an image. When targeting tonal ranges the mask itself is self-feathering, helping to avoid problems with blending and hard transitions.
