Adobe Photoshop CS Design Professional LAYER FUNCTIONS WORKING WITH SPECIAL

Chapter G2Working with Special Layer Functions Use a layer mask with a selection Work with layer masks and layer content Control pixels to blend colors Eliminate a layer mask Use an adjustment layer Create a clipping mask Chapter Lessons

Chapter G3Working with Special Layer Functions Use special layer features to modify an entire image or an entire layer Define the precise area to manipulate in each layer Adjust the appearance of each layer without altering the original image Using Special Layer Features

Chapter G4Working with Special Layer Functions Layer Functions Turn changes on or off Align images Blend and adjust color Combine elements to enhance an image

Chapter G5Working with Special Layer Functions Use a Layer Mask with a Selection Understanding Layer Masks Layer masks can cover an entire layer or specific areas within a layer Masks are flexible: –Hide their effect when viewing the image or change the masks Add an unlimited number of masks to an image: –One mask per layer

Chapter G6Working with Special Layer Functions Creating a Layer Mask Use tools on the toolbox to create the area to mask Apply the mask to the selection or to everything except the selection Feather the edges of the selection, if required

Chapter G7Working with Special Layer Functions Traditional Definition of Mask The term Mask comes from printing: –A mask was opaque material or tape used to block off an area of the artwork that would not be printed MASK

Chapter G8Working with Special Layer Functions Painting a Layer Mask Add a layer mask to a layer Reshape the layer mask with the Brush tool and a specific brush size or tip

Chapter G9Working with Special Layer Functions Painting on a Black Foreground If the image is painted with a black foreground, the size of the mask increases: –Each brush stroke hides pixels on the image layer –Paint with black to hide pixels

Chapter G10Working with Special Layer Functions Layer Mask Example Layer mask thumbnail Layer mask is black to hide pixels School Bus layer

Chapter G11Working with Special Layer Functions Painting on a White Foreground If the image is painted with white as the foreground, the size of the mask decreases: –Each brush stroke restores pixels of the layer object –Paint with white to reveal pixels

Chapter G12Working with Special Layer Functions Correcting a Mask Switch the foreground and background colors and paint over the mistake The Layer mask thumbnail on the Layer palette updates itself to reflect changes made to the mask

Chapter G13Working with Special Layer Functions Work with Layer Masks and Layer Content Understanding Layers and Masks The layer mask is a powerful editing tool: –Allows repeated editing of an image without ever disturbing the original pixels that make up the image By default, the mask is linked to the layer: –When the layer is moved, the mask moves as well

Chapter G14Working with Special Layer Functions Understanding the Link Icon The Link icon appears when a layer mask is created and when layers or layer sets are linked When creating a layer mask, the link icon appears between the layer thumbnail and the layer mask thumbnail

Chapter G15Working with Special Layer Functions Linking Layers Group or link layers to make multiple layers into one layer To link layers, the layer (not the layer mask) must be active –Link the active layer to other layers, even those in different layer sets –Link entire layer sets to a single layer or to other layer sets

Chapter G16Working with Special Layer Functions Using Linked Layers After linking layers, perform actions that affect the linked group; for example: –Moving the content of linked layers as a single unit Unlink layers by clicking the Indicates if layer is linked button for each layer to unlink

Chapter G17Working with Special Layer Functions Aligning Linked Layers To align multiple layers: –Link the layers on the Layers palette –Select one of the six options from the Align Linked command on the Layer menu

Chapter G18Working with Special Layer Functions Aligned Layers Centers of the Bananas, Nuts, and Blueberries layers are aligned

Chapter G19Working with Special Layer Functions Distributing Linked Layers To distribute means to evenly space content Distributing procedure: –Link three or more layers –Verify opacity settings are 50% or greater –Select one of the six options from the Distribute Linked command on the Layer menu

Chapter G20Working with Special Layer Functions Transforming Objects Use 1 of 10 transform commands on the Edit menu to transform an object Choose a transforming command: –A bounding box appears around the object to be transformed –A bounding box is a rectangle that surrounds an image and contains handles used to change dimensions

Chapter G21Working with Special Layer Functions Bounding Box Bounding Box with selection handles surrounds object to be transformed

Chapter G22Working with Special Layer Functions Transforming Sequence Select the object Choose a transform command or a sequence of transform commands Apply changes by clicking the Commit transform button on the tool options bar

Chapter G23Working with Special Layer Functions Transforming Examples Strawberries scaled Nuts rotated Before After

Chapter G24Working with Special Layer Functions Control Pixels to Blend Colors Blending Pixels Control the colors and form of an image by blending pixels on one layer with pixels on another layer Blending options are located in the Layer Style dialog box

Chapter G25Working with Special Layer Functions Layer Style Dialog Box

Chapter G26Working with Special Layer Functions Controlling Blending Control how pixels are blended by choosing a color as the Blend If color –The Blend If color determines the color range for the pixels to blend Use the This Layer and Underlying Layer sliders

Chapter G27Working with Special Layer Functions Blending Example Before Pixels Blended After Pixels Blended

Chapter G28Working with Special Layer Functions Sliders This Layer sliders –Specify the range of pixels that will be blended on the active layer Underlying Layer sliders –Specify the range of pixels that will be blended on all the lower—but still visible—layers

Chapter G29Working with Special Layer Functions Using Duplicate Layers Create interesting effects by duplicating layers: –Click the layer to duplicate –Click the Layers palette list arrow –Click Duplicate Layer, then click OK

Chapter G30Working with Special Layer Functions Eliminate a Layer Mask Disabling Layer Masks Disable a layer mask to: –Create duplicate layers and layer masks –Apply different styles and affects to layer masks –Show and hide layer masks individually to find the mask that gives the desired look

Chapter G31Working with Special Layer Functions Removing Layer Masks Options for removing layer masks: –Apply the mask to the layer so that it becomes a permanent part of the layer –Discard the mask and its effect completely

Chapter G32Working with Special Layer Functions Use an Adjustment Layer Understanding Adjustment Layers A special layer that acts as a color filter for all the layers beneath Create an adjustment layer to adjust color and tone Color changes made to the adjust-ment layer exist only in the adjustment layer, leaving the original layer unchanged

Chapter G33Working with Special Layer Functions Creating an Adjustment Layer Select the layer to adjust Use the Layer menu to click a new adjustments layer command or by clicking the Create new fill or adjustment layer button on the Layers palette Specify which of the 11 color adjustments are required

Chapter G34Working with Special Layer Functions Sample Adjustment Layer New Adjustment Layer added to the Layers palette

Chapter G35Working with Special Layer Functions Color Adjustments Selective Color Channel Mixer Gradient Map Invert Threshold Posterize Levels Curves Color Balance Brightness/ Contrast Hue/Saturation

Chapter G36Working with Special Layer Functions Working with Adjustment Layers Modify an adjustment layer by double- clicking the layer thumbnail on the adjustment layer Use as many adjustment layers as required, but create each layer individually Merge adjustment layers with any visible layers in the image, including linked layers

Chapter G37Working with Special Layer Functions Create a Clipping Mask Understanding Clipping Masks Group of two or more contiguous layers Used when one layer is to act as the mask for other layers or if the adjustment layer is to affect only the layer directly beneath it Bottom layer of a clipping group is called the base layer and serves as the group’s mask

Chapter G38Working with Special Layer Functions Creating a Clipping Mask Two layers are required: –One to create the shape of the mask –One to supply the content for the mask Either a type or an image layer can be used to create the clipping group shape

Chapter G39Working with Special Layer Functions Clipping Mask Sample Clipped texture appeared in the layer

Chapter G40Working with Special Layer Functions Removing a Clipping Group Layers in a clipping group are grouped together Ungroup the layers to remove the clipping group

Chapter G41Working with Special Layer Functions Chapter G Tasks Understand layer masks Create a layer mask Link layers Align and distribute linked layers Transform objects

Chapter G42Working with Special Layer Functions Chapter G Tasks Blend pixels Eliminate a layer mask Create and use an adjustment layer Create a clipping mask
