Direction Unit - Photo Replacement

In my movie I wanted a clip where my main character looked at a picture with him and his ex-fiancée when they were together. Since non of my actors had met before and taking a photo, editing the size and printing it to have it during the real shot, was a bit time consuming, I decided to use a technique called Photo Replacement.

During the filming day I used an empty frame with white background and made the actor look at it as if there was something in there.

After that, during post-production, I put a picture I took and blended it to the color and light of the clip so it looked real. Since the shot seemed a bit static after I did it, I decided to give it the movement that it had in the original clip, which was why I created a mask around the frame so I leave the frame static, but the still have movement in the surroundings. Here a picture of the final composition.
