Back in the days of 35mm film, we often got "loading shots" that were kind of interesting. Extra frames at the beginning of the roll that you'd crank off when reloading in a hurry to make sure the first frame you shot would be on unexposed film. This afternoon I lowered the camera to check the histogram on a shot with extremely bright clouds, to make sure I'd compensated enough to keep the clouds from blowing out. The view on the LCD, when I turned off the review, looked just like one of those 35mm loading shots. So I shot it.
