The rain returned in earnest a minute or so after I caught this moment. Lens: Canon 17/4.0 TS-E.
At Shelley Lake in Raleigh, rain began to fall as I set up a panoramic photo. I completed the three overlapping shots that I blended into the final image, then packed and left as a real downpour commenced. I wasn't in the mood to be a lightning rod. Lens: Canon 16-35/2.8 @ 16 mm.
Both of these were situations where a tripod was almost a necessity, in the first case to allow full control over the results of lens movements (tilt and shift), and in the second case to ensure good alignment of multiple images so that I could know what my upper and lower edges would look like when the whole composition was stitched together.
