<p>Hello,</p> <p>Honestly, I do not know the nuances of Passport, but I just took two headshot photos of a person in the exact same light with the passport next to the face. After importing into LR5, selecting my camera profile, and doing the light balance thing I find a similar point on the face will give a 100˚K change. Is this of any significance? </p> <p>I find it quite striking the color change in viewing a print in five different light sources (Solex, incandescent A & B, overcast daylight, and fluorescent)! I'm wondering how a professional portrait photographer could ever produce a print not knowing the light source the customer will view the print (s). </p> <p>Having 'Fun'.</p> <p>ChasB.</p>
