Descrizione

What’s the optimal approach for raw film scanning?

Scan linearly without applying channel-specific gains, keeping the raw dynamic range intact and let the inversion algorithm handle the color model transformation and density subtraction downstream.

or

Apply analog or digital gain adjustments to the green and blue channels during the initial capture to compensate for the mask.

Would we get more dynamic range if we apply gain to the blue and green channels?
