This has been a lot of fun to come up with. I was doing some edge-lit acrylic stuff, which led me to playing with multiple layers. I was doing the vehicle diagram plaques and one layer is full-color RGB that you can change with a remote and the top layer was just lit up in white with a brightness knob because if the background is lit up blue, the white has to be brighter. But with red, a lower-energy color, the white has to be dimmed or it will wash it out.
Anyway, playing with these layers I naturally got curious about three layers. Which led me to this Adjustable Luxograph. I took an RGB image, separated the channel information, etched it into the acrylic and then edge lit it with a dimmer knob for each layer. There’s a pretty powerful learning curve because basically, I’m taking a digital, additive-color model and producing it using a subtractive-color print method in light. There’s some really interesting adjustments that have to be made to the issue to counteract something analogous to the dot gain you get from certain types of paper.
