Unexpected natural effects...

I was out taking some spring shots and discovered an effect I hadn't payed attention to before...
Old, thin bark was hanging out from a couple of branches and sunlight illuminated these thin bark pieces from "behind", making them glow...

Glowing bark...

and closer...

...and very close.

Two more spring shots:

Stinking hellebore (Helleborus foetidus)

Common whitlowgrass (Draba verna)
- these flowers are really, really tiny! I should try to shoot them with a macro lens in the future, I think.

I did it today, and it was not easy :smile:.
The flowers are only ca 5 cm (2 inches) tall, and they are even hard to find using your eyes... :smile:

Some more macro shots I took when I was at it...

And some spring plants coming up...

Back to last year's Knoxville / Oak Ridge trip...

The city of Oak Ridge was opened to the general public in 1949. Security checkpoints at entrances to the entire area were replaced by checkpoints between the city and the sensitive sites where its residents worked, such as the K-25 plant.

This parking lot for this station is now a bike/hike trailhead for the adjacent nature preserve.

"Just one more thing" from last year's Knoxville / Oak Ridge trip. On the way home, I took highway US-25 through Hot Springs NC.

The Appalachian Trail runs through the center of town, marked by an emblem in the sidewalk.

Then across the Asheville-Knoxville railroad, along the other side of the road in this view.

Past the Hot Springs Resort, which served as an internment camp for noncombatant Germans during World War I. At a stamp show, possibly the one I visited in Knoxville on this trip, I saw an exhibit of mail to and from this camp.

And finally across the French Broad River via the highway bridge.

The gray ones are about 1 cm in diameter, and the straw orange one is about 2 cm in diameter. I did not try to measure.

Those first two, some kind of "mycela", were gone when looking there again a couple hours later.

On my way home from Florida in December, I spent the night just off I-95 in Kingsland GA. I had enough time before dark to drive to the nearby coastal town of St. Marys and look around a bit.

If I pass that way again, maybe I'll check out the rates at the Goodbread Inn.

The Kings Bay submarine base is nearby, so there's a submarine museum here. It had just closed for the day.

This well (or what's left of it) dates to the year George Washington died (1799), or maybe the following year since he died in December.

A hike (of course) but on a known trail, so we didn't look for themes - they just kept coming anyway...

So, some spring things:

An 'unknown, but strange enough' mushroom (?):

They are everywhere on a lawn. What's their name?
I have no identity information about them. THESE here were only found in one limited area at the edge of the lawn. They seem to have occurred over not more than a two-day period.

My viewing of the composition field has some tool buttons along the top. There is found a rectangle with a design suggesting a mountain-view; and this button is between a chain link and a smily face. You may use the "insert image" button to begin adding your image to your post.

Yet again you complain about PF when the problem is entirely yours.

Either
  1. stop using a browser that does not comply with web standards, or
  2. stop complaining when this causes you problems.
Do you not see how inappropriate it is to waste others' time in this way?

Not true. Somehow, PF doesn't like webp files.

PF may not be able to display *.webp images (I'm not sure about that). If the image is *.jpg or similar, and you have explicit BB Codes turned off (toggle the [ ] icon in the toolbar so that the other icons are gray and not red), you should be able to paste in those images.
 
Hmm... Now the image file on the original website shows up as a .jpg and it will copy-and-paste here.

Before pasteing in my first post (#2661 above, https://www.physicsforums.com/posts/7249584), I previewed the copied image in Irfan View (image viewer & editor) and it reported the file as a .webp and asked if I wanted it converted to .jpg. I responded "No" and pasted it in the above-mentioned post.

Either the source site changed the file type, or my computer had a headache yesterday (I'm getting one now!).

Here it is again using the same procedure (Irfan View did not ask to convert to .jpg this time).

I vote we write it off as poltergeists and move on.

Cheers,
Tom

But how do you think it became a webp file?
How does that relate to PF not supporting correctly webp images? A format supported by ALL current browsers.

When I click on "Insert image" and want to select a file (tested with Firefox), PF sets up a file filter to restrict the selection to supported types, i.e. jpeg, png, gif, and webp. Yet, webp doesn't work as expected on the forum?
