Juniper and star trails near Olmsted Point, Yosemite
Here’s a new image, made last Tuesday evening near Olmsted Point in Yosemite. My friend Mike Osborne calls this the “Bowsprit” tree. What? I didn’t get it either until he explained that a bowsprit is the bent figure with arms splayed back at the bow of old sailing ships. Okay, yeah, this does sort of resemble that.
Anyway, I “painted” this wonderful tree with a flashlight, and used the image-stacking technique to get noise-free star trails. With image stacking the idea is to take a series of short exposures and blend them together, rather than doing one long one. The total exposure time here is about 90 minutes, but one exposure that long would end up being quite noisy. Instead I took 24 four-minute exposures, with only a one-second interval between them. So each of those four-minute exposures has little noise.

Corn lily circle
A heavy winter, wet spring, and late snowmelt have all conspired to delay the wildflower bloom in the Yosemite high country, but it’s now in full swing. It’s a fantastic year for corn lilies—those plants with the sculpted, photogenic leaves and tall stalks of white blossoms. The Crane Flat Meadows are full of them, more than I’ve ever seen before, but these flowers are abundant in all the meadows between 6000 and 8000 feet right now. I made the accompanying photos in McGurk Meadow, where I found a nice mix of corn lilies and paintbrush.
These displays just the beginning. With all the residual moisture from melting snow, it promises to be a good—though late—wildflower year. Some spots may not peak until the end of August or even the beginning of September.
