Layers Build the Image
Layers are the architecture of a flexible Photoshop document. Build the image as a stack of decisions instead of one flattened result.
Think in editable pieces.
A composite is easier to understand when every meaningful element can be isolated, moved, hidden, corrected, or replaced without destroying the rest of the image.
- Keep meaningful subjects on their own layers.
- Separate atmosphere, lighting, background and foreground decisions.
- Hide a layer to understand what it contributes.
- Preserve choices so revisions stay possible.
Masking Reveal, Don't Erase
Masking lets you change your mind. That single principle is one of the biggest differences between exploratory work and destructive editing.
A mask is permission, not destruction.
Erasing throws pixels away. Masking lets you decide what is visible while keeping the source available for another decision.
- White reveals. Black conceals. Gray gives partial transparency.
- Work on the mask, not the image, whenever possible.
- Hair, glass, smoke, fabric and hard geometry need different edge treatment.
- Zoom out regularly: a perfect edge can still look wrong in the whole composition.
Blending Make the Pieces Belong
Blend modes are relationships between pixels. Use them as a means to an end, not as a menu of special effects.
Start with intent.
Screen is often useful for light, Multiply for darkening, and Overlay or Soft Light for contrast and texture. Then reduce the effect until it belongs in the image instead of announcing itself.
The best blend mode is rarely the most dramatic one. It is the one that helps the pieces feel like they were photographed, drawn, or illuminated in the same world.
Composite Make One World
A convincing composite is not about hiding the technique. It is about making every visual decision support the same scene.
Bring the pieces together.
Correct scale, perspective, color, light, edge quality and atmosphere until the viewer stops asking where the pieces came from.
- Match the light: direction, softness and color temperature.
- Match the depth: foreground contrast and detail should differ from distant elements.
- Unify the color with global grading.
- Keep an escape route using Smart Objects, masks and adjustment layers.
Separate
Break the scene into useful, editable parts.
Control
Use masks and adjustments instead of destructive edits.
Unify
Match light, color, perspective, texture and atmosphere.
Refine
Inspect the whole image, then return to the details that still call attention to themselves.
