How do you change part of an image in Photoshop?
Create a patch, or copy detail to another area in the image
To patch the Source (the selected area), drag the selection to an area that contains matching detail that will cover the object you want to remove. To patch the Destination, drag the selection to another part of the image. The selected pixels are copied there.
How do you crop around a picture?
Click the picture. Click Picture Tools > Format, and in the Size group, click the arrow under Crop. From the menu that appears, select Aspect Ratio, then click the ratio that you want. A crop rectangle appears, showing you how the picture will appear when cropped to the selected aspect ratio.
How do you cut something out of a picture and paste it into another?
To copy the selected area, choose Edit > Copy (from the Edit menu at the top of your screen). Then, open up the image into which you’d like to paste the object and choose Edit > Paste.
