Here’s one where the exposure took more than fifteen seconds. That’s a long time to sit still and not blink. I didn’t manage it. Not only did I blink, but I lifted my hand to my left eye because it was itchy. Yet none of this appears in the photo, which strikes me as weird but ultimately rather cool. (I’ll leave you to unpick that modifier, since imprecision, and even some level of impressionism are at play here already.)
