Monitor Screen 2

I shot this photo with my cell phone camera. I placed a piece of scotch tape across the lens. I quickly realized that for any image to be visible I had to point to a strong light source.

I pointed the camera at my computer monitor and realized that these odd stripes were visible, with no additional information from the screen. I am certain that there is something technical about this that I do not immediately understand--something about the light frequency on the (CRT) monitor.

I this case, therefore, I was taking a photo of something that I could not see.
