You can change the particular portion that you selected with the tool. This graphical process can help you change a few details of the image subject. It is most helpful when you are clicking images of models or products. This service is available on different platforms, not only Photoshop. However, It will be better for you to hire someone professional as these works need a lot of care and practice. The most common service of image masking is hair masking images.
