The local Gardens deprived me of my Mass Chrysanthemum fix this fall, so I dug up my pictures from years past. Here's a couple:

October Gardens
I expected to see banks
upon banks of chrysanthemums, begging to be photographed. But there
weren't many this year. I also saw:
Giant Mexican Marigolds

Even Newer Natural History
| Helianthus ferreus |
A splendid example of the
American Toolflower (Helianthus ferreus). The Toolflower requires
a temperate climate, plenty of sun and iron-rich soil. It is often
found in abandoned farmlands and gardens. The Toolflower is highly
susceptible to fungal infections such as Stem Rust, Black Rust, and, in fact, pretty much any kind of rust.

Back to the Garden
This time I got several
unblurred (almost) pictures of things that were further than six feet
away. I continue my slow, steady progress toward becoming this
century's Ansel Adams.

Picture This
A few weeks ago, in order
to do a post about a local street sign, I dug out my old, cheap
digital camera that I hadn't used in years. This weekend I took it
for a spin in the gardens at a nearby regional park. The results were
pretty sad. I took ten pictures, and eight of them were blurred and
unusable; including, unfortunately, a zoomed-in picture of a
goldfinch in some flowers. The other two you see above.
It was a cloudy day, and I
guess the problem was the shutter had to stay open too long, and I
couldn't hold the camera steady enough. I don't know why the two that
worked, worked. I'll try again on a sunny day and see what happens. I
suppose a tripod would fix the problem, but I'm damned if I'm going
to be seen using a tripod with a Nikon CoolPix.
For those of you who are
interested in the botanical details: the top picture is some kind of
dogwood, and the bottom one is some purple flowers and orange-leaved
plants in a big concrete pot.

Study: Taking a photo of something impairs your memory of it
"Around 50 undergraduates viewed paintings one at a time onscreen. In one block, participants took a photo of each painting with a smartphone, and then had 15 seconds to look at the painting itself. In a second experimental block, the participants took a photo of each painting, deleted the photo immediately (so they knew it could never been accessed in the future), then had 15 seconds to look at the painting. Finally, in another experimental block, they took no photos and simply viewed each painting for 15 seconds."
After a ten minute delay (during which phones were confiscated) came a multiple- choice memory test probing what the participants remembered about the various paintings. Compared to paintings that were simply viewed, performance was poorer for paintings that were photographed. Critically, this was true both for the condition where the photo was stored, and for the condition where it was deleted, meaning the participant knew they could not rely on it as a future memory partner.
This suggests that offloading may not be the cause of the memory disadvantage associated with taking photos. One alternative explanation is that using a camera forces us to disengage from properly taking in the stimulus, as our attention flows to the mechanics of operating buttons, checking brightness, exposure etc. This is something commonly reported by people as part of their photo-taking experience, and also tallies with the fact that automatic wearable cameras that store images for later don’t produce the memory impairment. However, in the current experiment, after taking pictures (or not), every participant had the same amount of time to take in the paintings without use of equipment, so any distraction effect would need to include some sort of delayed effect on memory processing even after the act of taking a photo was over.
Soares and Storm have a speculative second interpretation....

"Like will-o’-the-wisps on a humid summer night, male blue ghost fireflies illuminate the woods near Brevard, North Carolina. This image was made by digitally stitching together more than 300 30-second exposures spanning four hours." (Link to expand)
"In this vertiginous view of Hong Kong, low clouds race above the Quarry Bay neighborhood, reflecting the city lights below. Most of the 18- to 20-story residential buildings in this shot were erected in 1972."
