Arc of the Low Summer Moon


Arc of the Summer MoonThe summer Full Moon arcs low across the southern sky, mimicking the path of the winter Sun.

This is a project I had in mind for the last month, and hoped to capture at the July Full Moon. A clear, dry, and cooperative night provide the chance.

The still images are composites of 40 images of the Moon traveling across the sky from dusk to dawn, taken at 10-minute intervals. They are layered onto a blend of background images of the 10 p.m. dusk sky (left), 2 a.m. middle-of-the-night sky (middle), and 5 a.m dawn sky (right).

As a bonus, the 10 p.m. sky shows some dark crepuscular rays in the twilight, while at 2 a.m. the Moon was in light cloud and surrounded by iridescent colours. By 5 a.m. denser clouds were moving in to obscure the Moon.

Arc of the Summer Moon

I shot the still image composite (above) and time-lapse movie (below) to illustrate the low arc of a summer Full Moon. In summer (June or July) the Full Moon sits at a similar place near the ecliptic as does the Sun in winter near the December solstice.

From the northern hemisphere the low position of the winter Sun gives us the short, cold days of winter. In summer, the similar low position of the Full Moon simply gives us a low Full Moon! But it is one that can be impressive and photogenic.

The time-lapse movie uses all 400 frames of the moving Moon superimposed onto the same background sky images, but now dissolving from one to the other.

 

The movie is 4K in resolution, though can be viewed at a smaller resolution to speed up playback if needed.


For the technically minded:

The Moon disks in the time-lapse and still composite come from a series of short 1/15-second exposures, short enough to record just the disks of the bright Moon set against a dark, underexposed sky.

I took these shots every minute, for 400 in total. They are blended into the bright background sky images using a Lighten blend mode, both in Photoshop for the still image, and in Final Cut for the movie.

The background sky images are longer exposures to record the sky colours, and stars (in the case of the 2 a.m. image). They are blended with gradient masks for the still image, but dissolved from one to the other in the time-lapse movie.

I shot the frames with a 15mm full-frame fish-eye lens and Canon 6D, with the camera not moved during the 7-hour shoot.

Rising of the “Strawberry” Moon


The Rising Strawberry Moon of June 9, 2017 (Composite)

The Full Moon of June rose into a twilight sky over a prairie pond. 

On June 9, the clouds cleared to present an ideal sky for capturing the rising of the so-called “Strawberry Moon,” the popular name for the Full Moon of June.

The lead image is a composite of 15 frames, taken at roughly 2.5-minute intervals and stacked in Photoshop with the Lighten blend mode.

The image below is a single frame.

The Rising Strawberry Moon of June 9, 2017
The rising Full Moon of June, dubbed the “Strawberry Moon” in the media, as seen rising over a prairie pond in southern Alberta, on June 9, 2017. This is a single exposure stack, from a time-lapse sequence of 1100 frames, with images taken at two second intervals. Shot with the Canon 6D and 200mm lens.
I set up beside a small local prairie pond, to shoot the moonrise over the water. Ducks enjoyed the view and a muskrat swam by at one point.

I shot over 1100 frames, at two-second intervals to create a time-lapse of the rising Moon, as it brightened and turned from yellow-orange (not quite strawberry pink) to a bright white.

Here’s the time-lapse vignette.

Click on HD for the best view.

While the Harvest Moon gets lots of PR, as this sequence shows any Full Moon can provide a fine sight, and look yellow, due to absorption of the blue wavelengths by the atmosphere as the Moon rises, or as it sets.

However, the timing can vary from Full Moon to Full Moon. This one was ideal, with it rising right at sunset. If the Moon comes up too late, the sky might have already darkened, producing too great a difference in brightness between the Moon and background sky to be photogenic.

But what of these Moon names? How authentic are they? 

Who called this the Strawberry Moon? Native Americans? No. Or at best only one or two nations. 

Check the site at Western Washington University at http://www.wwu.edu/depts/skywise/indianmoons.html and you’ll see there were an enormous number of names in use, assuming even this listing is authentic. 

The names like “Strawberry Moon” that are popularized in the media today come from the American Farmers Almanac, and everyone – science writers and bloggers – ends up copying and pasting the same wrong, or at best misleading, information from the Almanac. 

Search for “Strawberry Moon” or “Moon names” and you’ll find the same explanation repeated verbatim and unquestioned by many writers. Alas, the Almanac is not an authoritative source – after all, they were the source of a misleading definition of Blue Moon decades ago. 

Yes, people around the world may have long had names for months and moons, but they were not necessarily the ones that make the rounds of news sites and blogs today. Most are a modern media concoction. A few years ago, pre-internet, no one knew about nor used these names.

The Lunar Eclipse, to True Scale


This is a multiple-exposure composite of the total lunar eclipse of Sunday, September 27, 2015, as shot from Writing-on-Stone Provincial Park, Alberta, Canada. From this location the Moon rose in the east at lower left already in partial eclipse. As it rose it moved into Earth’s shadow and became more red and the sky darkened from twilight to night, bringing out the stars. Then, as the Moon continued to rise higher it emerged from the shadow, at upper right, and returned to being a brilliant Moon again, here overexposed and now illuminating the landscape with moonlight. The disks of the Moon become overexposed here as the sky darkened because I was setting exposures to show the sky and landscape well, not just the Moon itself. That’s because I shot the frames used to assemble this multiple-exposure still image primarily for use as a time-lapse movie where I wanted the entire scene well exposed in each frame. Indeed, for this still image composite of the eclipse from beginning to end, I selected just 40 frames taken at 5-minute intervals, out of 530 I shot in total, taken at 15- to 30-second intervals for the full time-lapse sequence. All were taken with a fixed camera, a Canon 6D, with a 35mm lens, to nicely frame the entire path of the Moon, from moonrise at left, until it left the frame at top right, as the partial eclipse was ending. The ground comes from a blend of 3 frames taken at the beginning, middle and end of the sequence, so is partly lit by twilight, moonlight and starlight. Lights at lower left are from the Park’s campground. The sky comes from a blend of 2 exposures: one from the middle of the eclipse when the sky was darkest and one from the end of the eclipse when the sky was now deep blue. The stars come from the mid-eclipse frame, a 30-second exposure. PLEASE NOTE: The size of the Moon and its path across the sky are accurate here, because all the images for this composite were taken with the same lens using a camera that did not m

My multiple-exposure composite shows the complete September 27, 2015 total lunar eclipse to true scale, with the Moon accurately depicted in size and position in the sky.

From my location at Writing-on-Stone Provincial Park in southern Alberta, Canada, the Moon rose in the east at lower left already in partial eclipse.

As it rose it moved into Earth’s shadow and became more red, while the sky darkened from twilight to night, bringing out the stars.

Then, as the Moon continued to rise higher it emerged from Earth’s shadow, at upper right, and returned to a brilliant Full Moon again, here overexposed and now illuminating the landscape with moonlight.


TECHNICAL

The disks of the Moon become overexposed in my composite as the sky darkened because I was setting exposures to show the sky and landscape well, not just the Moon itself. That’s because I shot these frames – and many more! – primarily for use as a time-lapse movie where I wanted the entire scene well exposed in each frame.

Indeed, for this still-image composite of the eclipse from beginning to end, I used just 40 frames taken at 5-minute intervals, selected from 530 I shot, taken at 15- to 30-second intervals for the full time-lapse sequence.

All were taken with a fixed camera, a Canon 6D, with a 35mm lens, to nicely frame the entire path of the Moon, from moonrise at lower left, until it exited the frame at top right, as the partial eclipse was ending.

In the interest of full disclosure, the ground comes from a blend of three frames taken at the beginning, middle, and end of the sequence, and so is partly lit by twilight and moonlight, to reveal the ground detail better than in the single starlit frame from mid-eclipse. Lights at lower left are from the Park’s campground.

The background sky comes from a blend of two exposures: one from the middle of the eclipse when the sky was darkest, and one from the end of the eclipse when the sky was now lit deep blue. The stars come from the mid-eclipse frame, a 30-second exposure.


MY RANT FOR REALITY

So, yes, this is certainly a composite assembled in Photoshop – a contrast to the old days of film where one might attempt such an image just by exposing the same piece of film multiple times, usually with little success.

However … the difference between this image and most you’ve seen on the web of this and other eclipses, is that the size of the Moon and its path across the sky are accurate, because all the images for this composite were taken with the same lens using a camera that did not move during the 3-hour eclipse.

This is how big the Moon actually appeared in the sky in relation to the ground and how it moved across the sky during the eclipse, in what is essentially a straight line, not a giant curving arc as in many viral eclipse images.

And, sorry if the size of the Moon seems disappointingly small, but it is small! This is what a lunar eclipse really looks like to correct scale.

By comparison, many lunar eclipse composites you’ve seen are made of giant moons shot with a telephoto lens that the photographer then pasted into a wide-angle sky scene, often badly, and pasted in locations on the frame that usually bear no resemblance to where the Moon actually was in the sky, but are just placed where the photographer thought would look the nicest.

You would never, ever do that for any other form of landscape photography, at least not without having your reputation tarnished. But with the Moon it seems anything is permitted, even amongst professional landscape photographers.

No, you cannot just place a Moon anywhere you like in your image, eclipse or no eclipse, then pass it off as a real image. Fantasy art perhaps. Fine. But not a photograph of nature.

Sorry for the rant, but I prefer accuracy over fantasy in such lunar eclipse scenes, which means NOT having monster-sized red Moons looming out of proportion and in the wrong place over a landscape. Use Photoshop to inform, not deceive.

The “Blue Moon” over Calgary


The Full Moon of July 31, 2015, an infamous “blue Moon”, the second Full Moon of July, rising over the skyline of Calgary, Alberta. This is one frame of a 480-frame time-lapse sequence taken with the Canon 60Da and 28-105mm lens. The location was Toronto Crescent.

The much-publicized “Blue Moon” of July rises over the skyline of Calgary.

Last night, July 31, many people looked east to see a wonderful moonrise. Did it look different than any other moonrise? No. But did it look great? You bet.

I set up my cameras at a site in northwest Calgary, picked for its sightline looking east-southeast over the downtown core of Calgary and directly toward the moonrise point.

I used the software The Photographer’s Ephemeris to plan the location and angles. It is wonderful for making sure you are in the right place at the right time for catching a photogenic moonset or moonset.

Here’s the screen shot from TPE that showed me where to be Friday evening. The blue line aims to the moonrise point.

IMG_2473

Of course, despite the planning the Moon did not look blue! Blue Moons, as they have come to be defined, never do. The term now means the second Full Moon in a calendar month. We had a Full Moon on Canada Day, July 1, and then enjoyed a second July Full Moon one lunar cycle later on July 31.

I shot the scene with two cameras, each shooting hundreds of frames for time-lapses, from which I extracted still images.

A short 1-minute music video of the result is here at Vimeo. Enlarge the screen and be sure HD is selected.


As a technical note, for the processing I used the latest version 4.2 of LRTimelapse and its new “Visual Deflicker” workflow which very nicely smooths out all the frame-to-frame flickering that can plague daytime and twilight shots taken under Auto Exposure.

While the shutter speed does constantly decrease, it does so in 1/3rd-f/stop steps, yielding stair-step jumps in brightness. LRT smooths all that out, with v4.2 doing a much better job than earlier versions.

Thanks for watching!

Moonrise Over Calgary


Full Moonrise over Calgary

The Full Moon rises over the skyline of Calgary on a clear spring night.

This was the moonrise on Sunday, May 3, as the Full Moon rose south of the main skyline of Calgary. The timing of last night’s Full Moon promised a great shot.

The Moon rose about 15 minutes before sunset, a timing that I was hoping would lead to a shot of the skyline lighting up red with the last rays of the setting Sun in the west as the Moon rose in the east.

Alas, horizon haze obscured the setting Sun and rising Moon. The Full Moon didn’t appear until a good 30 minutes after moonrise as it rose above the haze into the pink twilight sky. Not quite what I was after, but it made a nice scene after all.

I shot this from the grounds of the CFCN TV building high on Broadcast Hill west of the city. There wasn’t an accessible site farther north with a clear sightline east that would have allowed me to place the Moon right over the city.

From this site at CFCN the Full Moon won’t rise over the downtown core until the Full Moon of September 27, the night of the total eclipse of the Moon. Photo op!

This is one frame of 430 I shot for a time-lapse sequence. To plan this and other rise and set images I use the handy app, The Photographer’s Ephemeris.

This screen shot from TPE illustrates last night’s moonrise geometry, with the moonrise line pointing just south of the downtown core as seen from the CFCN site.

I highly recommend TPE for planning any nightscape photography of the rising and setting Sun and Moon.

Moonlighting at Monument Valley


Moonrise Behind the Mittens at Monument Valley (#1)

The Full Moon rises behind the famous Mitten buttes at Monument Valley.

I spent a fabulous weekend capturing sunsets and nightscapes at the iconic Monument Valley on the Utah/Arizona border, the photogenic outdoor set of dozens movies over the decades.

On the eve of the total lunar eclipse I shot the nearly Full Moon rising behind the West (left) and East (centre) Mittens and Merrick Butte (at right). On the evening of Friday, April 3 the Moon rose and sat amid the sunlit clouds with the Sun still up.

The alignment that would place the Moon directly opposite the Sun to create the eclipse was still 11 hours away.

Note how the butte’s shadows point almost, but not quite directly, at the nearly Full Moon. They point at the place in the sky the Moon would be before dawn at the end of that night.

Indeed, on eclipse morning on Saturday, April 4 the Moon set exactly as the Sun rose (see my photos in my previous blog).

But on eclipse eve the Moon rose 30 minutes before the Sun set, providing a chance to catch the Moon behind the still sunlit red buttes.

Moonrise Behind the Mittens at Monument Valley (#2)

I shot this image about 20 minutes after sunset on April 3, so the foreground is now in shadow but the Moon appears in a more richly tinted twilight sky.

Orion and Venus Setting at Monument Valley

Later on April 3 I captured this scene, with the Tear Drop and Rock Door Mesas now lit by a bright Full Moon, and with the stars of the winter sky setting into the west. Canis Major and Orion are at left, while Taurus, including the Pleiades star cluster and brilliant Venus, are at right.

The Orion & Venus image is a 2-panel panorama.

Moonbeams at Monument Valley

On the evening of April 4, clouds thwarted plans for a long star trail sequence above a moonlit foreground.

Instead, I shot toward the Moon and clouds, to capture subtle moonbeams radiating out from the Moon, now some 14 hours after the eclipse, rising behind Merrick Butte. I shot this from the dusty Loop Road that winds through the valley floor.

Big Dipper over West Mitten, Monument Valley

Instead of lots of images for a star trail composite, I was content to shoot this one image, catching the Big Dipper in a brief hole in the drifting clouds, hanging in the sky over the West Mitten butte. The foreground is lit by the partly obscured Full Moon. The long exposure streaks the moving clouds.

Night or day, it’s hard not to take a great photo here, clouds or not!

Sunset Panorama at Monument Valley

On my final evening at Monument Valley, high winds common to the area, blowing dust, and the closed Loop Road, scuttled plans again for long star trail sequences from the valley floor.

So on Easter Sunday, April 5, I settled for a panorama from the classic viewpoint showing the setting Sun lighting the buttes and mesas of Monument Valley.

It is an amazing place, but one that still requires patience to wait out the clouds and dust storms.

Copper Moon over a Copper Mine


Copper Moon over Copper Mine

A coppery Moon rises over the Santa Rita Copper Mine. 

The March 5 Full Moon was the smallest Full Moon of 2015, the “apogee” Moon. Or call it the March mini-Moon.

I captured it rising over the vast Santa Rita Mine, east of Silver City, New Mexico, my winter home this year. The Santa Rita mine is one of the oldest continuously operating mines in western North America. I shot the scene from a viewpoint west of the city, using a 135mm telephoto lens.

The image is a composite stack of two exposures taken moments apart: a long 1-second exposure for the sky and ground (but with the Moon overexposed) and a short 1/13-second exposure for the lunar disk to retain details in the disk, like the lunar mare, marking the face of the “man in the Moon.”

The March Mini-Moon

Later in the evening I used my telescope to shoot a close-up of the apogee Moon. I shot a single exposure but processed it with exaggerated vibrance, saturation and contrast to bring out the subtle colour differences in the lunar mare. You can see that some are much bluer than others, due to the higher level of titanium in the lava flows that formed these mare.

As I explained in my previous blog, in seven months the Full Moon will be at the close perigee point in the Moon’s orbit, giving us the closest Full Moon of 2015. That’s also the night of a total eclipse of the Moon. I’ll try to shoot the Full Moon with the same telescope to create a big and small Moon comparison pair.
