Morning, CB! Time for Newbie Nate’s Question of the Day!
Reading through my textbook again, came across a description of RGB/RGBW fixtures that featured gel frames (particularly cheapie units).
Wut?
Hold the phone, I thought the point of a tricolor or quadcolor LED system is to additively mix the color you desire? Isn’t adding a subtractive filter (like a gel or dichroic) the equivalent of using a water filter to remove minerals you previously added for taste?
I understand that, with a pure white engine such as a Source 4WRD, using subtractive filtering is still a legitimate thing; after all, you’re producing as much of a full spectrum as you can, and filtering so you can get nice saturated colors. But filtering the white light produced by weak RGBW or worse yet, RGB, seems absolutely silly.
Can someone either 1) confirm that RGB/RGBW+gel frames is moronic or 2) confirm that I’m silly and don’t understand the point?
Unrelated P.S.: I’m compiling all of my “Question of the Day”s into a little guide that I might post somewhere at some point so other learning non-degree-holding LDs can learn something. Thoughts? (Or redundant?)
