1) If we place a couple of white balance cards (from different manufacturers) side by side, we can notice that they all look slightly different. How can I be sure -- before buying one -- which white balance card is the correct one?
2) I have a many-years-old Kodak 18% grey card. Does one have to replace the card after certain number of years? I am unable to make out if the card that I have is still 'accurate'.
Thanks in advance.
