For selecting and removing a background in Photoshop, the Quick Selection Tool and Magic Wand Tool are commonly used for their ease and efficiency in selecting areas with similar colors. For more precise control, the Pen Tool allows you to create detailed paths around the subject. After making your selection, refine the edges using the Select and Mask workspace to ensure a clean, seamless removal. Layer masks can then be applied to hide or reveal parts of the image non-destructively.
