What is the role of tablet pressure sensitivity (e.g., Wacom) when using brushes in Photoshop?
Article Introduction：Pressure sensitivity plays a key role in Photoshop brushes, allowing users to control line thickness, transparency, etc. through the strength of the stylus. When enabled, light pressure can produce thin and translucent lines, while heavy pressure will be thicker and more solid. The Pen Pressure control can be turned on for size, opacity and flow in Brush Settings to achieve dynamic adjustments. Its advantages include natural line drawings, better control of brushstroke fading and more expressive painting effects. When setting, make sure that the brush options and tablet driver are configured correctly in Photoshop, such as checking the pressure level and calibration in the center of the Wacom desktop. Frequently asked questions include Photoshop not identifying stylus, discomfort in pressure curves, or drawing delays, and double check the settings and adjust the pressure curve for the best experience.
