Changing Light

Here are 3 of my best pics from the “Bounced Color” exercise. My iPhone had difficulty picking up the color that bouncing onto the walls and floor. I used a sheet of frosted acrylic as a diffuser to help with the lighting source issue I was also facing.

 

 

Here, like the original pics, a diffuser was used and an Ottlite to give a more even distribution of light. You can see that the space gets “warmer” when the light is hovering over the left and right sides, and “cooler” when it is in the middle.

 

This one is using no diffuser, but rather a roof with a 15% opening. I used a flashlight for this demonstration and tried to more accurately mimic the sun’s path through the day. The color rods are noticeably more effective with color bouncing upwards off of them.

So, in the early part of the day, the sun’s position would give the room a warmer feel. When the sun has reached its peak, the room is cooler looking. And then as the day comes to a close, the room seems to warm up again.

 

For this, I just put the display on its back and tested what would happen if light came from behind the color rods and through the diffuser. It’s an interesting “scan” effect that does achieve some bounced color.
