Can anyone help me with this one please? The manual says to shoot "a white subject, just as you would take a normal picture" but how white is "white". If I'm shooting under studio flash lighting against a typical "superwhite" paper background, would this suffice? I assume that correct exposure as determined from an incident flash meter would be requisite but typically the histogram shows the highlights (ie the white background) falling well short of 255 - does this matter. I've also seen reference to use of a grey card (although not in the Canon manual) - help!!
