Adobe Photoshop CC 2015 for Mac: A Detailed Operation Guide

Adobe Photoshop CC 2015 is the core image processing software in the Adobe Creative Cloud suite, renowned for its powerful raster editing, compositing, and design capabilities. This guide will provide a detailed introduction to its interface, complete workflow, and operational tips.

I. Detailed Explanation of the Software’s Core Interface and Workspace

After launching Photoshop CC 2015, you will see an integrated workspace composed of multiple panels and areas.

1. Menu Bar: Located at the top of the screen, it contains all major command categories such as “File,” “Edit,” “Image,” and “Layer.”
2. Options Bar (Control Panel): Positioned directly below the menu bar, its content changes dynamically based on the currently selected tool, and it is used to set the specific parameters of the tool.
3. Toolbar: By default located on the left side of the interface, it brings together all editing tools such as selection, cropping, brush, stamp, and text. Tool icons with a small triangle in the lower right corner indicate hidden tool groups.
4. Document Window: The central area, displaying the image file currently being edited. Each opened file is arranged as a tab.
5. Panel Area: By default stacked on the right side of the interface, it is the core control area for the software’s functions, mainly including:
   • Layers Panel: Manages all layers, groups, and layer effects in the document, and is the foundation for compositing operations.
   • Color/Color Panel: Used to select and store foreground and background colors.
   • Adjustments Panel: Provides quick access to create non-destructive adjustment layers (such as Curves, Hue/Saturation).
   • History Panel: Records operation steps, allowing you to revert to a previous state.
   • Properties Panel: Displays detailed parameters of the currently selected layer, mask, or adjustment layer.
6. Status Bar: Located at the bottom of the document window, displaying information such as the current document’s zoom ratio and file size.

You can switch between different preset workspaces (such as “Painting” and “Photography”) via the “Window” > “Workspace” menu to suit specific tasks.

II. Complete Workflow: From Creation to Export

1. Create or Open a Project

Method: After launching the software, select “File” in the menu bar.

• New File: Click “File” > “New” (shortcut Cmd + N). In the dialog box that appears, set the name, dimensions, resolution, color mode, and background contents.
• Open an Existing File: Click “File” > “Open” (shortcut Cmd + O), and select the image file you need to edit in the dialog.

2. Basic Image Editing and Compositing

This is the core stage of the workflow, typically involving the following operations:

a. Image Adjustments: Under the “Image” menu, use the commands in the “Adjustments” submenu (such as “Brightness/Contrast,” “Levels” Cmd + L, “Curves” Cmd + M) to directly modify pixels. Using the “Adjustments Panel” to create adjustment layers is more recommended, as it enables non-destructive editing.

b. Using Layers: It is recommended to place all elements on separate layers.

• Creating a New Layer: Click the “Create a new layer” icon at the bottom of the Layers panel, or press Shift+Cmd+N.
• Layer Operations: Drag layers in the Layers panel to change their stacking order. Use the icons at the bottom of the panel to add layer styles (such as drop shadow, outer glow), layer masks, or group layers (Cmd + G).

c. Editing with Tools:

• Selection Tools: Use the Rectangular Marquee (M), Lasso (L), Quick Selection (W), and other tools to select areas, then copy, move, or make local adjustments.
• Retouching Tools: Use the Spot Healing Brush (J) and Clone Stamp (S) to remove blemishes; use the Brush tool (B) for painting.
• Transform: After selecting a layer, press Cmd + T to enter Free Transform mode, allowing you to scale, rotate, and distort the selection or layer.

3. Save and Export Files

a. Save the project file: To preserve all layers and editing information, you must save it as a native Photoshop format.

• Click “File” > “Save” (Cmd + S); the first time you save, a dialog box will pop up.
• Choose the save location, select “Photoshop (*.PSD; *.PDD)” as the format, and click “Save”.

b. Export as a universal image format: For web publishing or sharing with others.

• Quick Export as PNG: Right-click on the layer and select “Quick Export as PNG”.
• “Save for Web”: Click “File” > “Export” > “Save for Web (Legacy)” (shortcut Opt+Shift+Cmd+S). In the pop-up window, you can choose the format (such as JPEG, PNG-8, PNG-24, GIF), optimize image quality and file size, and then click “Save”.
• Regular export: Click “File” > “Export” > “Quick Export as PNG” or “Export As…” for more settings.

III. Advanced Tips for Common Features

1. Non-destructive editing system: Use adjustment layers, layer masks, smart objects, and layer styles whenever possible. After converting a layer to a smart object (right-click the layer > “Convert to Smart Object”), you can scale or apply filters to it and modify the parameters at any time without loss.
2. Advanced Selection Techniques: Enter the “Select and Mask” workspace (called “Refine Edge” in older versions) to finely process complex selection edges such as hair. Use the “Color Range” command (under the “Select” menu) to quickly create selections based on color.
3. Brush and Mask Advanced Tips: When the Brush tool (B) is selected, use the shortcuts [ and ] to quickly decrease or increase brush hardness. On a layer mask, paint with a black brush to hide parts of the layer, and paint with a white brush to reveal them again—this is a key technique for compositing images.
4. Content-Aware Fill and Healing: Use the “Fill” command (under the Edit menu) (Shift+F5), and choose “Content-Aware” in the Contents options to intelligently remove unwanted objects or fill the selection.
