Moving the Texture slider increases or decreases the appearance of texture in the photo. Sliding to the right enhances medium-sized details (good for revealing foliage), while sliding to the left diminishes those medium-sized details (good for giving skin a smoother appearance). If you’re editing portraits, use the Adjustment Brush tool to paint over features you want to smooth, like your subject’s cheeks and forehead, and move the slider to the left. Or you might do the opposite. Sharpen the eyes, eyelashes, and hair by painting those with the brush and moving the Texture slider to the right.
