I spotted this lone bristlecone pine tree on my first drive up Mount Evans. The uniquely shaped tree alone on the side of the mountain begged to be in an image and on the last day of this trip, I made that pine my sunrise subject.
A clear sky does not hold promise for an amazing sunrise or sunset, but what can be counted on is the opportunity to incorporate a great sunstar into the image.
To create a sunstar from a point light source requires a narrow aperture. The narrower the aperture, the bigger the sunstar is the rule. I often select f/16 for these types of images as the effects of diffraction are usually tolerable at this aperture, even on the highest resolution cameras. A downside to using a narrow aperture with the sun in the frame is that flare effects are increased, especially from lenses with high element counts. Whether or not the flare shapes are attractive and desired may be a personal preference. Also note that, in general, wide aperture lenses create the largest sunstars.
Nikon Z 14-30mm f/4 S Lens' f/4 aperture isn't terribly wide and in this case, I opted for f/22 to get a larger and more attractive (including stronger points) star. I don't like the softness that diffraction creates at f/22 so the portion of the frame without the sunstar in it was merged from an f/11-captured frame. I captured a 5-shot bracket (varying by 1 stop) at each aperture setting and opted to use a brighter f/11 image for the foreground.
The other property a clear sky can promise is a very warm light immediately after the sun rises or immediately before the sun sets and the warm first or last light of the day raking over a scene is often welcomed from a landscape photography perspective.
The small crescent moon included in the frame just above the left side of the pine tree was a bonus for this image.
