Here's the only half-way decent shot I got of the Empire mechanical TV at the ETF convention This set has 45 lines, 3:1 interlace. The exposure was 1/2 second, hand-held, and the result was still very dim. I processed the image by increasing the gain about 2 or 2.5 times. You should be able to make out the subject, which was converted to this format from NTSC. I suggest viewing this from far away. I don't know if the three fields were really so different in brightness as they appear.

If Steve McVoy is reading, can you tell us what the light source is? Looks neon-color, but could be using an LED.
