Greetings and thanks for your consideration of this question.
I have a number of corporate headshots across the country that I am shooting for a client. The biggest complaint of the current headshots is inconsistency in color be it skin tone and background.
I use a gray card however I get very disappointing and inconsistent results. I used a gray background with 2 lights for the existing portraits. I end up sampling with the picker on the background.
Fortunately we have eliminated the background light so the possibility of inconsistency from the background light and Key light is eliminated.
I know I need a better gray card. Anyone know the best one to buy? I purchased one and is plastic. It shoots very blue.
My camera is a Mrkiii and my raw editing is Capture 1. I use a small octodome on a Dyna-lite.
* Or is the question "how do I get my monitior more consistent?" I tether when I capture but use a iMAC 27" to process. Both monitors get calibrated.
