I get questions about photography every so often. A picture is worth a thousand words. Telling someone to use a pop-up light tent in full sun might not be particularly helpful, especially since what I use is officially called "Lite Tent." So, here is said pop-up light tent, which you can buy here . I position it so the sunlight is hitting the top and two sides. This gives a nice back-lit shadow, creating a sense of depth.
I hope you are having a wonderful Labor Day weekend.
