The document describes editing a magazine cover by copying and pasting sections of a base image to ensure the models' heads appear in front of a larger masthead. Key steps include: 1) Cropping pieces from the original image to paste onto the cover, such as a section of hair behind a model's head. 2) Using tools like the lasso and transform to scale and position the pasted sections so they blend in with the models and place the heads in front of the masthead as desired. 3) Adjusting the scale of pasted sections until they appear natural as part of the final edited cover image.
