Video documentation of test | password: gradproj
notes
initial intention
The initial intention was to see the effects of projecting into a spherical mirror, focusing on how the image is spread to cover a large area (over 180 degrees of view).
inputs [projected materials]
Video file.
modifiers
None (other than the spherical mirror).
output [screen(s)]
Large sized projection, the spherical mirror reflecting the image into a more than 180 degree projection.
back end
Spherical mirror / silver coated ball
conclusion
The problem with projecting using a spherical mirror is that the light is spread almost too much and therefore actually lights up a dark space. Secondly, the contrast, intensity and visibility of the image is lowered, and projecting graphical videos results in an image that is difficult to distinguish. This is also the reason why the projected image in the test is a photographic moving image. That being said, if the actual camera (in the source material) is moving a lot, the effect of the whole room moving is quite strong. I see this technique being used to create an ambiance in the space, and although seeing the whole room moving is strong, I think a 360 degree synced projection and out of multiple projectors could be stronger due to the higher quality of the image.
