Cairo is one of the most polluted places in the world. I remember thinking I had a bad cold the whole time I was there — but the minute I left Cairo to head to West Africa, I was totally fine. It turns out I had insane allergies to Cairo’s dust. Also, I remember coming home every day thinking I got a tan and again I’d be surprised by the layer of dirt that had gathered from the air onto my skin. Ok — I think I made the point that there’s a ton of dust in Cairo’s air, but that same dust makes for AMAZING light and amazing photos in late afternoons and at sunset time.
