I should read photos the way other people read palms. I'd look at the lines, study the wrinkles and recesses. Feel the texture, consider the pliability and color of it.
I wouldn't forget proportion or scale or relative flatness or roundness. I'd read that photo carefully, slowly, looking for signs and warnings, ominous forbiddings and hopeful protections.
And after contemplating it long enough, I'd tell you exactly what it means.
