But you are looking at objects illuminated by the sun and those objects are reflecting IR. My camera with IR filter takes pictures in the sun with no problems at shutter speeds in the 1/250 of a second range while taking a picture of my Kobo H20 in a dark room with a finger on the screen shows no image after a 20 second exposure.

I do remember playing with Kodak's HSI infra-red film decades back. The black sky, the white foliage. One of my favourite B&W films which is sadly no longer available. On the other hand, I don't miss the sheer waste when bracketing each exposure since no light meters (that I was aware of) were calibrated for IR photography.
