Hi Patrick
Thanks for your reply. I did read though article and it did cross my mind regarding the Luminance etc, I just didn’t want to confuse anyone too much who would read my post.
I will pass on this info to the photographer.
Thanks you for the amazing amount of info within the Colorwiki site. I wish I had found this years ago!
Thanks again for the replies.
Hope you all have a great Christmas and new year!
