How can you have a scene linear reflectance greater than 100%?

Re: How can you have a scene linear reflectance greater than 100%?

Those numbers from 0 to 720 look like mV values for the luminance channel. Is that what you’re asking about?

I was looking at the curve of SLOG3 but didn't understand how light can be reflected more than a 100%? This indicates to me that 100% reflectance isn't really 100% and that instead it's in relation to some standard. Consequently, this would indicate that 18% gray reflectance isn't reflecting 18% of all light either. Could someone please explain what exactly is happening here? Thanks.
