[QUOTE="merryoncherry, post: 127112, member: 37249"] A lot of thoughts here, maybe I can hit the answer to your question... The xLights brightness slider I can think of scales the brightness of an effect, which has its own range 0-255, to a new range 0-255. So, if your original effect was too dim, you could use a setting over 100%. (Try it with a gray or grey "On" effect to see for yourself, if you crank it down it gets darker gray and if up it goes toward white.) This is more useful with something like an image, which has a lot of color range in it, and can't be controlled by color choices directly. As for the granularity, if you set brightness to 1, you're saying it outputs 2, but I'm guessing that is when the original effect is at 255. There'd be some original range that produces 0 and 1 also. Yes, the result is going to be low fidelity to the original colors. 8 bit has somewhat limited dynamic range. I think it is not necessary, but while you can't slide the slider to fractional values, you could put 1.5 in the text. You mention the sensitivity at the bottom end, you should read about "gamma". If you haven't read about it yet, you'll find that the situation is even worse than you think. The "1" value is often pretty bright, and only 7 colors can be that dim, for more variety you have to use values much bigger than 1 that quickly become a few times brighter. [/QUOTE]

The title of our introductory lighting manual contains a three digit number. What is that number? Clue: Display basics forum
