This exercise was completed by cropping the guy from the middle image and adding him into the background shown on the right. Once he was placed onto it, the lighting had to be adjusted so it matched the pattern shown in the background. For example, the lighting in the picture of the guy is coming from the right; casting a shadow on the left side. In the background, the light come from the left and casts a shadow on the right. The guy had to be reversed and the lighting had to be adjusted to match. The final image is shown on the right.
For this exercise, I was given the middle image and had to fix it so it matched the image on the left. This was done using tools such as clone stamp, paint brush, and light and contrast adjustments. My final images are shown on the far right.
For this excercise, I started with the original image of myself on the left and used many techniques to age myself. One tutorial is shown here.
