Here Ginny is using her iPhone inside the tomb of Khety (tomb #17 at Beni Hasan, 11th Dynasty under Mentuhotep II). Theoretically, you can't use a camera inside the tombs unless you have a permit, but you can use a phone. It turns out the iPhone does quite well. My iPhone 12 Pro Max has a low light setting which seems to give good results. Ginny does very well with her iPhone seven plus.
