I have a black wall with inscription and carvings Everything is in black. The wall is lit by bright sunlight. How do I take the picture of this wall showing the details of the inscriptions and the carvings. 1. Should I apply the sunny 16 rule and come up with a perfect exposure. 2. Should I meter the incident sunlight and determine my exposure 3. Should I meter the reflected light from the wall and underexpose by 1 stop as black has the reflectance of 9% and my meter is based on 18% grey tone.
