The Mount Desert Island Historical Society beautifully maintains the Somesville Bridge, Selectmen's Building, and the surrounding grounds. This includes planter boxes that always hold attractive flowering plant arrangements in the fall. These planters beg to be included in the frame, but including the plants, the bridge, and the building in the same frame requires extreme depth of field for all details to be sharp. Extreme depth of field generally requires a very narrow aperture, and a very narrow aperture generally results in a diffraction-softened image.
Focus bracketing solves this problem.
For this picture, the focal length that best composed the scene was first selected, and the Really Right Stuff TVC-24L Mk2 Tripod with an RRS BH-40 Ball Head was moved into a somewhat awkward position to lock the composition down. ISO 100 was selected for the least noise, f/11 was selected to gain a significant depth of field for each image (f/8 would have been a good alternative in hindsight), and the shutter speed, 1/10 sec., was selected for the final exposure brightness, just bright enough to cause minor overexposed highlights on the bridge (blinking during image review). The R5's "Focus bracketing" was enabled and the "Number of bracketed shots" was set to 15.
With the lens in AF mode, the focus spot was placed over the closest subject, the ornamental cabbage flower. When the shutter release was pressed using the 2-second self-timer mode, the camera took a series of images. While I selected 15 bracketed shots in the menu, the camera knew that only four were required for this scenario.
In Canon Digital Photo Professional (DPP), the four RAW images were selected, and the Tools > Depth Compositing > Start depth compositing tool menu option was selected. The default settings were used to output a 16-bit TIFF file that only required minor adjustments unrelated to focus.
My wife thinks the cabbage is too big relative to the background elements, but moving into the street to capture a more distant view was not a good idea from a safety perspective,
and that perspective would have resulted in sidewalk and other less attractive elements being included in the frame.
Harder to argue against is that the flowers provide lots of color in the frame.
Regardless, hopefully the ease of creating a focus bracketed image with the Canon EOS R5 and EOS R6 is illuminated.
