Aerial photographs of Madison, Wisconsin in winter — all from the "blue hour."

By Jeff Miller at the UW website.

Details about "blue hour photography" here.
Also known as twilight, the Blue Hour happens every day just before sunrise and just after sunset. It’s like an extra reward for photographers who stay later or arrive early for the Golden Hour. Unlike the Golden Hour, though, the Blue Hour is typically much shorter than one hour. In some places, it’s over within 15 minutes–or barely happens at all....

Generally, the best Blue Hour shots have sources of artificial light, such as street lamps or city lights. This warm light contrasts the dark blue, giving your photos a wider range of color. Without this light, your images could end up looking too blue or colorless....

Well, the photographs do look blue or almost colorless.

The effect can be augmented by using Tungsten white balance (in the old days, film), which increases blue in ordinary light, and putting an Orange Gel over the flash to counterbalance the blue on the subject. This is why indoor images often look orange with a normal white balance but "normal" when taken with the Tungsten setting.

Just saying.

Lucky to have a college with a small airfield a few miles away with planes for rent, Aeronca 7AC in this case.

All the buildings have been renamed for more worthy people now.

It's all about simultaneous contrast to create a good vibration

"Home of the Wisconsin Badgers, a snow-covered Camp Randall Stadium appears to have more than 80,000 open seats."

Appears? I'm pretty sure they really are empty. Even mine.

My favorite Blue Hour photography is from film - the scene in "LA Story" where Steve Martin and the female lead, his once and future wife, are fighting on the beach.

Of course, that movie in general is beautifully filmed. Sigh. Oh, California...

Some of them look like the "Golden Hour". Very pretty.

Mixing natural and artificial light was a classic architectural photography technique. Not only are the images often very pleasing, it avoids having the featureless black shadow areas that you can end up with in sunlight, due to the limited subject brightness range of color film.

You set up and then wait until the level of illumination is about equal between the interior and exterior spaces, and make the exposure then.

With digital cameras, you can blend shadow- and highlight-optimized exposures using "high dynamic range" (HDR) software. The results, to my eye at least, often seem unnatural and cartoonish, but I seem to be in the minority there.

I looked at the article and its pics. After all these years, I am totally amazed at the discussions people with color vision have about what they see. However, we color blind people see things that "normal" visioned people cannot see. So, one must presume it all balances in the end.

John Ray: have you tried the color blind glasses yet? It's phenomenal how bright red is

I see a land full of zombies. It looks apocalyptic, nuclear winter, not a warm-bodied soul anywhere above ground.

Here in Vegas yesterday it was crazy weather: first measurable snow in over a decade, and it snowed on and off all day long with occasional hail storms. It was pandemonium I tell ya!

The snow pack in the Sierras is 4 times what it was last year. Getting close to 150% of normal. That is good news for millions of us across a huge part of the nation out west. We got water, which I hear is pretty important.

I'm in awe that in the 21st century we are still totally dependent on the weather, and other environmental factors completely beyond our control. We forget that we still really only have hope we are not destroyed by nature.
