Does “Color Science” even matter?

You might have spotted the difference in the exposure settings. I ran 1/3 stop brackets and selected the frames in which the brightest patches landed at L* = 92. However the Fuji persisted on requiring double the nominal exposure.

Why did Fuji require double the exposure at the same fstop and base iso? Does that mean the fuji is half as sensitive as the Nikons?

I have previously noticed that the base ISO 64 Nikon cameras are more sensitive than you’d expect.

How do they achieve it? Are their sensors more sensitive to light?

This is a matter of how the specifications of the camera are created. I think that product management plays a large role here.

Ah I get it. I was under the assumption that the iso scale is a standardized scale, meaning an iso 100 was the same across all brands. I guess iso 200 of one brand could mean iso 100 of another brand.

The ISO scales are standardized but there are 2 standards being used: SOS vs REI for digital sensors. Nikon uses REI while Fujifilm uses SOS.

I have no idea why anyone would create a standard with 2 different variations.
