Learn how to chroma key in Photoshop to remove green backgrounds and replace them with custom scenes using simple, non-destructive editing steps.
Before following the step-by-step guide on how to chroma key in Photoshop, it's important to first understand what chroma keying is and how it works.
Chroma keying is a visual effects technique used to remove a solid-colored background (usually green or blue) from an image or video. This allows you to replace that background with any scene, texture, or graphic of your choice.
The process works by identifying a specific color range (typically bright green, which is uncommon in skin tones or clothing) and making it transparent, so only the subject remains visible. In Adobe Photoshop, this is done through selection tools, masks, and layer adjustments.

Adjust:

Feather (for soft transitions)
Contrast and Shift Edge as needed.
Output to Layer Mask and click OK.
Step 5: Remove the green background
Remove the selected green background by clicking the Delete button.
Step 6: Add a New Background
Drag and drop or place a new background layer below your subject.
Use Transform (Ctrl+T) to resize and position the new background as needed.
Pro Tips:
Avoid green spill on the subject by using Select > Modify > Expand before masking.
If green tones remain on edges, use Hue/Saturation adjustment with green channel selected and reduce saturation.
For hair or fine details, consider using Channels for advanced masking.
