I'm trying to get the best self-portrait possible, and the problem I'm running into is that to see the portait as you are shooting it (assuming a tethered DSLR setup or equivalent), you need to avert your eyes from the camera to look at the screen, which alters the look of the eyes, making it impossible to see your own facial expression.
So I'm thinking about placing a one-way mirror halfway between the camera and myself, and shooting with a remote control.
This way, the reflection in the mirror will approximately be the same image seen by the camera and the eyes will be looking at the virtual image of the eyes, which will be in the same position of the camera, thus effectively looking at the camera. Meanwhile, the camera will be able to shoot through the mirror just fine, except for reduced incoming light.
To make the one-way mirror work, the mirror and the camera would need to be enclosed in some kind of box-like structure blocking light and thus creating a dark chamber containing the camera and with the mirror as a window.
And here's the question: has anyone tried anything like this? Does it actually work? Any suggestions on the simplest/cheapest way to build this?
