I'm looking for guidance. I'm trying to enhance the inscriptions on some old tombstones from the 1700's. The inscriptions.names and dates are barely visible on some. The adobe forum pointed me in this direction. I successfully downloaded and installed the RTI program on my Mac running 10.14 using the terminal program. Can I use a stationary tripod positioned in front of a tombstone and use a standard "studio light" positioned at many different angle to light the face of the stone? Can I place the spheres on the top of the tombstone?
