Pondering Illuminant Metamerism – Or, Get a Life!

While at my desk recently, (sitting there thoughtless – for me, a common place to be,) I took this picture of the ceiling above, which slants down to a skylight.

What’s interesting, or not, is the fact that except for the window, the same color paint was used on the same type surface. Only the angle of the outside lighting is different. Yes, it’s called Illuminant Metamerism, and was a consideration for which colorants (pigments) were to be utilized in my early career in the color matching science. Ultimatly that  led to “getting a (good) life” in my chosen career field.

There’s no point in zooming in on this image, but as usual, comments are always welcome. M:-)

A Total Eclipse Family Event – 8/21/17

My wife and I (and Sandy Paws, the dog,) journeyed about 750 miles (1200 km) from New Jersey to see and photograph the Total Solar Eclipse last week, meeting up with most of our immediate family for an unforgettable, awesome event which none of us, including the youngest, will ever forget.

Through a very dense solar filter, these first two images show the moon in silhouette, moving slowly from upper right to lower left across the sun. Click on to see the sunspots near the center, and lower left limb.

Totality descended rapidly in the final seconds… exposing this unreal, and unforgetable sight, joined by gasps and “Oh my God, it’s beautiful (s)..” Fontana Village is a resort in western North Carolina, today within the “path of totality,” a ~70 mile (113 km) shadow area – this time moving west to east across the United States. Above,  the sun’s outer corona is captured.
Above: Totally eclipsed over two minutes, the sun just ….reappears. This shorter exposure shows the inner corona and solar flares (reddish bursts to the right and lower right of the sun,) often referred to as the ‘Diamond Ring effect.”
As the moon continues along, gradually exposing more of the sun… the strong filters and solar glasses are again required, as the landscape moves from deep twilight to full daylight in a little over an hour.
Besides finding it hard to concentrate on the quickly changing demands of eclipse photography, the totality is unlike anything you could ever experience. Spontaneous applause and cheers welled up from the field in a unified expression of being witness to something extraordinary.

Accompanied in the field by our children, their children; my brother and sister-in-law, and Sandy Paws, we appreiciated such a beautiful day for an exceptional event just south of the Great Smoky Mountains.

America’s Cup 2017 – How The Wealthy Play

Coinciding with our vacation to Bermuda last week, was the America’s Cup Yacht Preliminaries.

As seen from the bow of our cruise ship, Norwegian Breakaway, the America’s Cup Village is seen just behind Celebrity Summit, in Bermuda’s Great Sound.
Over the preceding months and many locations, preliminary races determined the ultimate “challenger” to the current “defender” (USA’s “Oracle.”) Above,  New Zealand’s “Emirates” (in contest with Great Britain’s “Land Rover”) takes the lead with Gibbs Hill Lighthouse in the background, and has now earned that challenger privilege.
The boats have evolved over 147 years, from more conventional sailing yachts, to highly refined and sophisticated racing platforms, now utilizing hydrofoils to significantly reduce drag and increase speed.
Rules prohibit any energy sources other than the sea, air and human input. The helmsman, (see image above) who is ultimately responsible for navigation and articulation of control surfaces under race conditions, must continuously evaluate and decide when and where to guide the boat and how to do it. His hands are on a multi-remote laced steering wheel. Also, as the boat’s direction and roll-attitude changes, the entire crew will run across to the opposite (upper) pontoon to man duplicate stations.  Great theater! 
Just after winning this heat over Land Rover, Emirates is seen here coming down off the foils. The boats often exceed 44 knots (50 mph) in racing.

Although all the 50′ catamarans  are essencially the same, teams have virtually unlimited options as to trimming and power usage, including navigating savvy, and human endurance.  For example, Emirates utilizes bicycle-like human power stations, while Oracle uses the more traditional hand cranked “grinders.”  The science of these vessels and the methods employed are awesome, details of which can be found here .

Shooting Venus – March 11, 2017

Venus is currently a crescent phase, as it swings quickly along its orbit between Earth and the sun. 

Nikon D5200 DSLR, cropped (enlarged) from original size (below.) f13, 600mm Tameron (150-600) telephoto, ISO 1250, 1/4000″ Handheld
Original frame of image on top, same capture, at 6:09 PM 3/11/17, 10 minutes after sunset. Venus is in the center. Can you see it??
For comparison, Tri-X film version with EXA 35mm camera, 1/25th sec, through 10″ Newtonian reflector telescope. Taken December 1st, 12:30 PM many years ago, and recently digitally post processed. Being so bright, it can be seen and photographed in the daytime. 

Venus has been shinning brightly for the last few months after sunset, but is quickly approaching what is called Inferior Conjunction, as it passes roughly between the Earth and the Sun in 11 days, 3/22/17. The planet will re-emerge as the “morning star” visible a week or two later, rising before sunrise.

Awesome Hyperbolic Paraboloid on W. 57th – Open Soon in NYC

 

Looking down W. 57th St. at twilight this week, four of the newest buildings including the second tallest in the city, dominate the view. But, look at the closest on the left….

dsc_0511-version-2

Designed by Danish Architect Bjark Inges, this spectacular residential building  features impressive amenities, and a spectacular open air court yard.  

“VIA 57 West” is so dramatically shaped that it looks different from every  viewpoint, as shown here from the west, (above) and north-west an hour earlier. (below)

Color My World… A “Retrospectic” Snippet

 

OLYMPUS DIGITAL CAMERA
OLYMPUS DIGITAL CAMERA

Exposure, lighting, shadows and geometry. The “algorithm” of the digital camera and the “mind” of the observer. That and more,  all play a part in what we ‘see’ in an image. In this case a glimpse back ten years from our family room, contrasting with the hall (wallpaper long since gone) and the “office.”  

From the “office,” apologies for creating new words,

thanks for viewing and

“Great Scott!” er… SPOT – Jupiter Collides with EARTH!

I dreamed that the Earth was being threatened by Jupiter’s “Great Red Spot!” 

dsc_0089

No, that’s not really true, not even the dream part.  BUT, the clouds above do look a little like planet Jupiter’s atmosphere with its “Great ‘Red’ Spot,” just above and behind the Oyster Creek nuclear power plant here in New Jersey! Furthermore, the smokestack may be attempting to suck power out of the “spot,” as JCP&L investigates more sustainable energy sources; similar to my previous suggestion raised  about New York’s Con Ed last year,  here,  

For reference, here is the real thing: (Stock photo from Wikipedia.)

And below, my younger day’s attempt at “astrophotography.”

Jupiter and its “Great Red Spot” (8″ f/12 reflector, 75x; EXA 35  mm SLR, 1/25th sec. Tri-X B&W film,) captured a long, long time ago in my parents back yard, way before digital imaging, and by today’s standards – pretty meager!
