Determine where in your home you'd like to install the corrugated tin wainscoting.
Find a section of the wainscoting area that is exposed to indirect natural light. If you can't find an indirect natural light area, find an area where the direct sunlight hits the corrugated tin at an angle, rather than straight on.
Tape a panel of corrugated tin wainscoting to the selected section with duct tape. Ensure the panel is flat against the wall and even with the floor and any side walls.
Turn off the flash on your camera.
Photograph the wainscoting from below the top edge of the panel. This will hide the lip that will be covered when you install the wainscoting.
Use a sheet of cardboard to block the natural light if the Sun is reflecting off the tin.
Increase the aperture setting on your camera if the cardboard is blocking too much light or the natural light is too dim.
Take a lot of pictures from different angles, but ensure you're taking the photos from areas that hide the wainscoting lip.
