I have a lot of video footage in first person view, dramatic scenery, and a photo of an old man.
I want to combine them to make a background picture (1920 x 1080) that should transmit the message: this is what he saw, this is what shaped his face.
I came up with a picture mosaic, mixing pictures of the raw footage, but I found this unconvincing.
Then I thought about showing the face of the old man and putting footage into his eyes as a reflection, but that would limit me to one or two pictures of the footage.
How can I combine more pictures while conveying the idea of the first person point of view?
