For my journals this week I also wanted to try creating some subtle light. Now I’m not really sure what that means completely but I took it to be some sort of faint glow effect. What I tried is taking my LED PAR lamp and focusing it with a double convex lens. If I had the lens out it front of the lamp far you could see the individual LEDs but if I had it close the lens would combine the RGB LEDs into a white light.

This is my LED PAR lamp with my double convex lens in front. By moving the lens I can focus the beams of light. With this PAR lamp I can control the red, green and blue LEDS individually and if I shine the PAR on an object the different color lights from the LEDs mix together and create different colors.

My goal was to create nice white light and then when I focused it with the lens we could see the individual RGB LEDS creating little pools of color. Subtle?…maybe not but interesting I think so! Also when I look at this all I can think of are clowns…not really sure why but the pools of light look like polka dots to me.
