In Photoshop, which tool is fastest for selecting a white background behind a subject to replace with another background?

• A. Lasso Tool
• B. Magic Wand Tool
• C. Quick Selection Tool
• D. Magnetic Lasso

Answer: (B)

The quickest way to grab a solid white background is by using color-based selection. The Magic Wand Tool selects areas of similar color with a single click, so a uniform white background can be picked fast—especially when you keep Contiguous enabled and tweak the Tolerance to cover slightly off-white areas. Once the background is selected, you can easily invert or delete and replace it with a new background. Other tools require tracing edges or brushing to grow the selection, which takes more time and can miss spots, whereas the Magic Wand capitalizes on the uniform color to make the background selection rapid.
