I am working currently on an art project.
My target: I apply around 1000 lumen of light through a key hole of a door lock. The light is supposed to go through the key hole and the outcome of the light on the other side, which is very tiny however visible, must be captured in a photograph, together with the lock and an object next to the lock.
The issue is the amount of weakened light that reaches the other side of the door. This amount must be increased or the source light must be amplified somehow.
To succeed I currently see two options:
I am thinking to increase the power of the light source (to about 3000 lumen).
The light outcome must be amplified/multiplied. I was thinking to use a mirror. After researching online I learned that the mirror will not significantly increase the light amount
I was wondering whether it is possible to amplify the power of light that comes out of the door lock?
Here we go an updated picture:
