I'm more inclined to leave that stuff to people with the equipment and time to do it properly. Taking a picture of a stone relief needs grazing-angled light, i.e. very precise timing for the sun angle or accurately placed artificial light. I took photos of the Sabian cult centre at Sogmatar nearby, and didn't get anything like the quality of this one:

because it was near-midday in the middle of summer, the sun left no shadows at all, and with the temperature at 45 Celsius and a minibus waiting I couldn't stick around to do better. So my picture of the moon god Sin (left in that picture) looks as flat as Queen Victoria on a worn penny.

Maybe if I can get there at dawn or sunset and find the site open.
