OK, Totally the wrong place to ask this, my bad. Looking more for a "Where Should I post" Also, knowing the wealth of experience in this forum thought I might push my luck;
We are doing a series of talks on theater lighting to Students in our smaller, Pavilion theatre. One of the subjects will be the spectral emissions produced by legacy (Tungsten) and LED lights, both simple RGB and RGBWA.
What I would like to be able to do is shine a lamp unto a white surface to demonstrate the effects of colored gels and for the LEDs mixtures of RG&B. What would be very effective would be to see a visible spectrum scan that would change as, say the RG&B percentages were altered in the mix.
I have seen some very expensive spectrum analyzers on the market but was wondering if there wasn't anything (software based and using a tablet's camera perhaps) that was around for a whole lot less. There are of course a huge number for the audio frequencies but I would have thought lighting engineers/techs/designers would like a way to assess a Lamp. GEL, LEDs color composition. Ideas?
