Where is 18% Gray Card on ColorChecker Passport?
Cannot locate the 18% Gray Card on the ColorChecker Passport.Technically speaking, the 4th patch from the white one in the bottom row of the ColorChecker classic is 18% gray. However, it would not be very practical to try to meter off of such a small patch. You would get much better results with the ColorChecker 18% Gray Balance target.
You also can use the exposure patches on the RAW Enhancement Card to check or correct your exposure.
