We heart it is a great resource site, for finding images. Thinking about these portraits which will have overlaid images I want to see how others have used overlay.
This picture reminded me of a portrait i made once.
Overlay can be a great technique, especially in portraiture, you can evoke emotions and feelings through layering 2 images. In this case I just want to try and define who the person is through their work.
One thing these photos teach me is that the more shadows and contrast their is the better the photo is, more flat pictures like the first and second one just create silhouettes whereas textured photos like the other 2 balance more with each other and play better.
