When to go
Best time
Morning, Late afternoon
I went to the lonely trees of Umm Bab Clay Quarry during April, but all months are great! My only recommendation would be that if you plan to really enjoy this spot, you might want to avoid the extremely hot summer months.
You can visit this location anytime, but in order to photograph similar lighting conditions, I recommend the late morning or late afternoon when the sun is bright, but not too harsh.
Additionally, sunrise and sunset are always beautiful times to visit the quarry.
Field tips
You'll have to drive off of the main road to reach this destination, so having a 4x4 vehicle is a must.
I shot the featured image with a 70mm focal length and I think having a 24-70mm lens will allow you to shoot a wide range of images, both from a wider perspective and a more compressed viewpoint.
Having a human subject will breathe some life into the photo—especially since the desert is so bare.
If you're styling your model, I recommend modest desert attire. The area is very deserted and you want to be protected from the elements.
