How to Remove Backgrounds Perfectly in Photoshop

Open your image in Photoshop. If the Layers panel shows a lock icon on the Background layer, click it to unlock, or drag it to the trash icon. This allows transparency. For best results, choose an image where the subject has good contrast against the background.

With the layer selected, go to Select > Subject in the top menu. Photoshop uses Adobe Sensei AI to automatically detect the main subject. This works remarkably well for people, animals, and prominent objects. Wait a few seconds while the marquee selection appears around your subject.

With the selection active, click the 'Add Layer Mask' icon at the bottom of the Layers panel (rectangle with a circle inside). This hides the background while preserving your original image completely — the mask is non-destructive, so you can always refine it later by painting on the mask thumbnail.

Select the Brush Tool (B), set white as the foreground color, and paint on the layer mask to reveal any hidden parts of your subject. Switch to black to hide any background remnants. Use a soft brush (0% hardness) for smooth transitions and a hard brush for sharp edges. Zoom in (Ctrl++) for detailed areas like hair.

For complex edges like hair or fur, click the layer mask thumbnail, then click 'Select and Mask' in the Properties panel. Use the 'Refine Edge Brush Tool' (the brush with feather icon) to paint over hair strands. Check 'Decontaminate Colors' to remove color fringing. Set Output to 'Layer Mask' and click OK for a professional result.
