I might have posted this shortly after I joined the forum. it's a poor scan of a slide, but it illustrates that if the location and conditions are right, you can get a powerfull image without clouds.

Curtis, is this the image where you mentioned the "earth shadow" and the "belt of Venus"...? I wasn't sure what you meant by earth shadow... or the belt of Venus!

earth shadow is a term I learned a few years ago from an Art Wolfe slide show I attended in Seattle. It's the dark blue band that slowly works it's way up or down the sky depending on whether it's sunrise or sunset.

Belt of Venus is a term I learned more recently from a NASA Astronomy pic of the Day. It's that pink band that you see if the conditions are right. It's not very common to see it in a mountainous region such as this, but the distance across the lake is great enough to provide a sufficiently distant horizon. The Belt of Venus is most commonly seen in flatter geography.

And I haven't the slightest clue how the Belt of Venus got its name... :rolleyes:

Really nice colors here and very minimalist and clean. The colors make it moody. The Belt of Venus seems to be more intense on hot days. I've seen some beautiful ones from Sherrard Point looking SE to Mt. Hood. I'll have to post one of my shots from there.

Thanks, Curtis - interesting! Here's the Wikipedia explanation on the Belt of Venus:

"The Belt of Venus or Venus's Girdle is the Victorian era name for an atmospheric phenomenon seen at sunrise and sunset. Shortly after sunset or shortly before sunrise the observer is, or is very nearly, surrounded by a pinkish glow or antitwilight arch that extends roughly 10¡Ð20¡ above the horizon. Often the glow is separated from the horizon by a dark layer, the shadow of Earth. The arch's light rose (pink) color is due to backscattering of reddened light from the rising or setting Sun. A very similar effect can be seen during a total eclipse of the Sun."

I guess I'd go with "belt" over "girdle", too...

Tom :wink:

i have a shot of this same phenomenon just touching the horizon, i'm not sure how i could post it here or if i should, but it did rescue an otherwise mundane photo

go ahead Michael. We could make this a Belt of Venus thread. :cool: or the girdle thread? hmm... maybe not...:eek:

just below the text box for replying to the thread, you should see another small text box and a browse button. the browse button will let you select a file from your local hard drive (or mapped network drive). Just make sure it's less than 200k filesize and it should upload when you click the reply button.

Curtis,
I remember this. I even remember my comment. I think I said "try taking just a little off the bottom". I kind of think maybe you did on this one. Very cool shot!
Posted by Rick Lundh on July 12, 2007 at 11:46 PM
Love the cool colors and the serene feeling in this one. I remember it well.
Posted by Curtis Knight on July 13, 2007 at 7:08 AM
Erik, yeah, I got lots of comments to crop the bottom, and I did, but in the end I preferred the full frame.

This is a shot from Michael Medina that he asked me to post on his behalf. Nice moody shot Michael!

Jeez! Both shots are great. I might take a little more off the bottom of your shot, Curtis, not a heck of a lot though.
Michael's shot is surreal!
