If you want to create rounded corners in Photoshop, there are a few different methods you can use. The easiest way is to use the Rectangular Marquee Tool (M) and draw a rectangle around the edge of the object you want to have a rounded corner. Then, use the Round Corners Tool (O) to create the rounded corners. Another method is to use the Pathfinder Tool (P) and click and drag one of the corner points to create a rounded corner. Finally, you can use the Free Transform Tool (T) to resize and reshape the object before applying the rounded corners. ..
