Radiance just happens, you cannot plan a radiant glow. It is a fleeting moment when the sun reflects in the right place at the right time. It needs no supernatural powers, it is all done by nature. As I sit in my office room in the afternoon writing I am often distracted by the sun shining on the trees. Now I have a choice. do I close the blinds to prevent the light distracting me or do I take my camera and see if there is something worth a photo. Need I find an explanation? I take the photo, because what is now happening is just a moment in time that will not repeat itself very often.
