Exposure Value

I know this may not sound very much like color management but I have to ask 😊 Here is a link to an Excel sheet where I compare the Exposure Value from my camera to the Exposure values calculated from a scene original photometric properties. https://1drv.ms/x/s!AkD78CVR1NBqkLVHRATQaJhc56YZww I suspect my camera “light meter” is kaput? But after going through the calculations, I’m not drawn to the same conclusion. If you have a chance and are familiar with Exposure Value determination, I would appreciate you give me some feedback on my equations. I think I’m on the right track but, since I never went through these equations before, I have a doubt. Best / Roger Breton www.graxx.ca
