This afternoon in Acadia National Park found the 17-28 RXD along with a Sony a7R IV in a MindShift Gear BackLight 18L on top of Bald Mountain anticipating a great light show at the end of the day. Unfortunately, that show mostly did not happen. The weather forecast did not hold true and as can be seen in this image, thick clouds ruled the sky.
Just when we thought there was no hope for seeing a sunset, a tiny hole appeared in the clouds and awesomeness shined through. I dropped the tripod into the nearest location that looked compositionally promising and shot a several frame bracket, ensuring that one image had bright foreground detail captured at f/11 and the darkest of two others had a tiny bit of color remaining in the sun. The latter two images were captured at f/22. While f/22 results in softer image quality than f/11, it delivers a larger, better quality starburst effect and the clouds nicely hide the softness in the portion of f/22 capture used in the final image. Note that changing the aperture changes the starburst including the orientation of the star points. When bracketing such images, be sure that most of the images containing the starburst are captured at the same aperture to avoid an awkward appearing composite.
By the end of the first bracket capture, the warm sunlight was no longer reaching the foreground and after a second bracket at a slightly adjusted camera position, the sun was completely cloud-blocked again. The foreground lighting was better in the first set of images and cropping those from the bottom gave me a result similar to those captured in the adjusted camera position.
I seldom use ISO settings above 100 when photographing daylight landscape but you will notice that a setting of 800 was used for this image.
Along with the heavy clouds came very strong winds and I was estimating the exposure duration that could be tolerated between gusts.

held solid and I probably could have used longer exposures — though sun time may not have permitted that.
