Introduction
Photoshop's layers, masks, and non-destructive editing tools will change how you approach photo editing. These features give you creative freedom and the flexibility to experiment without damaging your original work. This chapter covers the essential skills you need to use these powerful tools effectively, keeping your edits both creative and reversible.
Lessons
Understanding and Creating Smart Objects
Smart objects preserve your image's source content and quality throughout the editing process.
Step 1: Open your image in Photoshop and select the layer you want to convert.
Step 2: Right-click the layer and choose "Convert to Smart Object" from the menu.
Step 3: Notice the small icon that appears on the layer thumbnail – this shows it's now a smart object.
Using smart objects means you can scale, rotate, and transform your image without losing quality.
Using Layer Masks for Non-Destructive Edits
Layer masks let you hide and reveal parts of your layer without deleting any pixels.
Step 1: Select the layer you want to mask.
Step 2: Click the "Add layer mask" icon at the bottom of the Layers panel (it looks like a rectangle with a circle inside).
Step 3: Select the brush tool. Paint with black to hide parts of the layer, and white to reveal them.
Try different brush hardness and opacity settings to create smooth blends between masked and unmasked areas.
Enhancing Images with Adjustment Layers
Adjustment layers change how your images look without touching the original pixels.
Step 1: Click the "New Adjustment Layer" icon in the Layers panel (the half-black, half-white circle) and pick the adjustment you need, like Brightness/Contrast.
Step 2: Adjust the settings until you get the look you want.
Step 3: To make an adjustment layer affect only the layer directly below it, right-click the adjustment layer and choose "Create Clipping Mask."
This approach keeps your editing flexible – you can always change or remove adjustments later.
Remember This
Layer masks and adjustment layers are essential for non-destructive editing. They mean you can always go back and change your edits without starting from scratch.
Practice
Create a simple composite image following these steps:
- Open two different photos in the same Photoshop document
- Use layer masks to blend them together naturally
- Add adjustment layers to match the lighting and colours between the images
- Convert one layer to a smart object and apply a transformation to it
- Save your work and try adjusting the masks and settings to see how flexible this workflow is
FAQs
What are layer masks in Photoshop?
Layer masks let you selectively hide and reveal parts of a layer without deleting any pixels. You can always edit or remove the mask later.
How do adjustment layers differ from direct adjustments?
Adjustment layers sit above your image layers and change how they look without altering the original pixels. Direct adjustments permanently change your image data.
Can smart objects be edited without losing quality?
Yes, smart objects preserve the original image data. You can resize, rotate, and transform them repeatedly without quality loss.
Jargon Buster
Smart Objects: Special layers that protect your original image data, letting you make changes without quality loss
Non-Destructive Editing: Editing techniques that preserve your original image while letting you make changes you can reverse or modify later
Adjustment Layers: Layers that change the appearance of layers below them without permanently altering the original image data
