An ICM of the Christmas tree lights.
This is one of the most complex of the ICMs I took of the tree this year. And it's taken me several years to work out what is going on with the lights and their dashed patterns.
The LED lights scintillate at high frequency though not at a frequency related to the mains supply. It's about 100Hz.
I thought for a while it was the rectifier in the control converting the AC to DC rather crudely. But it's not that I think.
The lights have a control programme that we normally use that gradually dims and then brightens the string. The scintillations are caused by the controller chopping the current supply to cause the dimming.
The scintillations are too fast for the eye to see (we can see up to about 20Hz in flickering which is why many TVs refresh their screens at 40-60Hz).
So this is more an interesting image than a pretty one, and demonstrates one feature of the difference between our perception of motion and the camera's. That's one of the things I wanted to explore in the 100x Motion project I set myself this year.
Thank you for taking the time to look. I hope you enjoy the image! Happy 100x :)
In the Kenroku-en Garden Kanazawa, 'one of the most beautiful landscaped gardens in Japan'. The garden was teeming with visitors at this time the probability of capturing a moment like this was minuscule. But there we are. The image shows Kenroku-en Garden itself was scintillating.
When the conditions are perfect, the SF skyline really does appear to float above the clouds. This was a sunrise shot taken last year when I got the best conditions of low fog out of all my visits. The fog layer was low, the Golden Gate towers stood majestically over the clouds, and the city skyline scintillated in the distance.
Counting the times I’ve headed up to Marin these past 1.5 years, I’ve only had 1.5 successes out of 8 tries, this being the best. The other half success was earlier this year up at Slacker Hill when I managed to snap off a few good shots before the fog layer thickened and prematurely ended the show. There has also been countless times when I decided not to head up only to wake up, turn on the computer, and see gorgeous low fog in the bay from Marin webcams. This morning, I was not to be denied.
I can stare at scenes of low fog from here for hours. I am ready and waiting for this fall season’s low fog to return. May the light be with you.

This is one of my favorite shots from a short outing with the Breeze-master (David) and the Ninja (Alan) at our location dubbed “Thompson’s Hallway”. Unlike previous boot camps, we limited ourselves to a single burger and we steered clear of the fried foods. As for weather conditions, we could not have asked for better. We had fog the first morning followed by sunlight with little wind. The next morning we witnessed an incredible sunrise with rarely ever seen cloud formations followed by an hour-long full arched rainbow. To top it off, the fall colors were scintillating at their peak both on the ground and on the trees.
This particular scene captivated me with its narrow hallways, leaves draped over the tops of the trees, and the plentiful foliage covering the ground. David was so excited seeing these groves he climaxed three times the first morning. Alan was so mesmerized at the scene that he took enough self-portraits for a lifetime of profile pictures.

Known for scintillating musicianship, vibrant playing, youthful style... and for taking their performances out of the concert hall and into the bars and clubs of East Coast America. Is this an approach that might attract new (and younger) audiences to (less stuffy) classical gigs in non-traditional venues?

What fascinates me is the play of light on water. The lake had just enough wind ripples to make the orange glow of this sunset shimmer on it's surface.

This image is not for everyone. But before you go, ask yourself, how could one light source create two twinkles (star-bursts)? Here's a hint: this was shot under a white Dogwood tree in full bloom about 30-40 seconds before totality on April 8th.
I look forward to your explanation, scientific or poetic. If the latter, I hope you rope in the scintillating Dogwood darkness in your poem.
The name St or Sankt Goar comes from a hermit come saint that decided to set up camp below a particularly nasty set of rapids in the river.
St Goar tended to those that were foolish enough to get stuck in the rapids and became known as a healer, this news spread and he ended up tending the sick of the area and since he was also a good host to the patients family he received he fed them as well.
The saintly man received enough funding from the nobility and his flock of recovered patients that he had a chapel and hospital soup kitchen of sorts built in place of his camp and became legend and the towns patron Saint.
Sankt Goar’s values must be ingrained into the people of the village they are particularly known on the Rhine as a most hospitable village and a good place to celebrate an occasion.

Disclaimer: Not trying to be realistic in my editing there is enough realism in the world, my style is a mix of painterly and romanticism as well as a work in progress.

We spent the entire day around Lake Chuzenji in Nikko photographing waterfalls. This is a free-entry viewpoint just outside a small cafe, but the limited space and foot traffic meant that everyone had to wait their turn to secure a good spot to capture the twin waterfalls surrounded by peak autumn foliage.

This was taken on the day after it snowed on Mt Fuji - you can still see the ring of snow on the mountain clearly demarcating the area that experienced heavy snowfall.
We were deciding between Chureito Pagoda or Fuji Twin Terrace, but ultimately decided upon this location since it was nearer and the overcast day meant that star trails from Fuji Twin Terrace may be a no-go. That, and the possibility of having to camp up there for the night for the stars.
Thankfully, the decision paid off in the end when the clouds gave way to a gloriously dramatic autumn sunset, coupled with snow on Mt Fuji which would be otherwise bare.
We were also discussing computational photography on phones, and how these days even low-end phones would have no issues capturing a dynamic scene like this in a single frame with the help of HDR algorithms. It would have been nice to have such a feature that can be toggled in standard cameras as well!

This was taken on a clear day right before it snowed on Mt Fuji - probably one of my few shots of Mt Fuji that I took without its iconic snowcap, but you do still get the sunset glow on the peak!

Shiraito Falls
It was raining pretty much throughout the entire day, making the weather rather chilly in Shizuoka. Still, we decided to make the trip down to Shiraito Falls even though the visibility of Mt Fuji was non-existent.
Although I would liked to have framed Shiraito Falls with the classic Mt Fuji viewpoint and rainbow, the rainy and foggy mood turned out beautifully for this wonderful set of multiple waterfalls as well.

Since Bunkyo Civic Centre was closed, a last minute decision to head to the i-link Town Observatory in Ichikawa turned out incredibly well with clear skies for the evening and the setting sun intersecting Tokyo Skytree from this viewpoint.
The vantage point from this observatory offers panoramic views of both Mt Fuji and different landmarks in Tokyo - you can see the silhouettes of Yoyogi Tower and the Tokyo Metropolitan Government Building in this frame (along with a few other iconic buildings as well).
We reached the observation deck early and managed to secure a good corner spot to frame our shots before the evening crowd came in. As it was a clear day, we had many local photographers joining us as well, and they all seem to have planned for this shot too - many of them wielding dual camera setups to avoid missing a key moment.
Despite being an enclosed area, it was still cold and windy as the roof allowed wind from the outside to pass through, so keeping our setups stable especially with long lenses was problematic. It was still worth all the trouble though, for this angle that we didn't plan for!

Tried to catch sunset from this location after a day of heavy rain but the sunlight fizzled out. Still, the very clear blue hour made up for it!

This was our view from the campground nearest to Kappa Bridge, at the start of the Kamikochi hiking trail. We camped here for a night before embarking on a 15km hike up Karasawa Hutte.
Originally intending to photograph star trails at this location since the North Star is framed nicely in the middle for this location, but the thick clouds obscured our view of both the night sky and the Hida mountain range.
Nevertheless, while looking through my raw files for usable frames, I came across this 8 minute exposure that was part of a sequence for the hour-long star trail that we did. The clouds, though thick, happened to positioned very dynamically for this scene. Though I'd still prefer a full hour-long of circular star trails in a clear night sky, I'm pretty satisfied with this exposure as well.

I just couldn't help taking pictures of these interesting fairy hairstreaks when in Ghana. I also wanted to know whether they were of different species.
It turned out to be in vain in Bobiri since these fairy hairstreaks were all Hypolycaena antifaunus (Large Fairy Hairstreak).
In Atewa, we came across smaller fairy hairstreaks with forewings about 11 mm. At first I thought they were all Hypolycaena lebona. However after checking all the photos, surprised to discover this is probably another species.
I guess it's Hypolycaena scintillans: most of spaces 1a and 1b are deep black, as shown in the above picture with enhanced black portion in forewing underside.
Any suggestion/comment on the ID is much appreciated.

Fujiyoshida Honcho Street
Without doubt the most famous street in Fujiyoshida - with a snow-dusted Mount Fuji looming in the background accompanied by a row of shops, old-timey lampposts and telephone lines leading towards the iconic mountain, it's not hard to guess why this is so!
Thanks to the prior's day heavy snowfall atop the mountain, we woke up to a mystical sight of Mount Fuji cladded in thick snow - you can even see the trees along the middle of the mountain covered in fresh snow as well.
It was good that we booked our accommodation along this road, which makes it convenient for us to catch the first light hitting the scene before other tourists arrived to photograph at this spot. That, along with a relatively quiet street in the early morning before it got too busy to capture a clean frame.

Taken at the end of a long rainy day in the Costa Rican rainforest, but it was worth it.
The resplendent quetzal is of great importance to a number of South American cultures, being present in various legends and myths. It was considered divine and associated with Quetzalcoatl, a feathered serpent and god of life, light, knowledge and the winds, by pre-Columbian Mesoamerican civilizations.
Its scintillating green tail feathers, symbolise spring plant growth, were venerated by the Aztec and Maya. Since the killing of quetzals was forbidden under the Mayas and Aztec criminal law, the bird was seized, its prolonged tail feathers deplumed, and was set loose (I'm not sure if they re-grow so feel sorry for the poor old male RQ).
In ancient Mayan culture, the quetzal feathers were considered so precious that they were even used as a medium of exchange. Thus the name of the Guatemala currency, the quetzal.

A live juvenile Hawaiian Bobtail Squid (1-2 mm wide) captured at 5x Magnification in salt water. The blue and yellow color in the background was produced from a VISA credit card placed out-of-focus behind the specimen, which depicts Starry Night (ironically) by Van Gogh. - See more at: review.wizehive.com/voting/view/nsfvizziesgallery/27425/3...
Description
This juvenile Hawaiian Bobtail squid is just one in a series of 5 images and short films, which were captured in order to understand the symbiosis between the Hawaiian bobtail squid, Euprymna scolopes, and the bioluminescent bacterium, Vibrio fischeri. The squid has complex external and internal organs that separate Vibrio fischeri from ocean water and position the bacterium throughout its' body. Considering that Hawaiian Bobtails are nocturnal, the bioluminescent bacterium are believed to disguise the squid from predation by mimicking the soft, scintillating glow of star light.
Intended Audience
Researchers in Molecular Cell Biology and other individuals researching the affects of symbiosis.
Purpose of Entry
The intended use of this entry is part 1 of 5 themed exhibits to be placed on display at the Connecticut State Natural History Museum, which is located in Storrs, CT at UConn's main campus. Each exhibit contains approximately 5 high-resolution macroscopic and microscopic images of specimens related to natural history.
Scientific Impact
Each of the 5 exhibits showcase the scientific work of 5 academic researchers at the University of Connecticut. They visually and effectively answer a complicated set of interdisciplinary research questions in ways that can be easily understood by students and individuals not having this particular type of expertise.

This was a small shrine in Matsumoto that was a stone's throw away from our hostel. We stopped by this place after dinner for some nighttime photography - just in time before the lights were turned off for the night.

Taken on our third and final day up the Hida Mountain Range, we were still blessed with clear morning skies when we returned to this vantage point to photograph the sunrise.
We had to be up from 5am to get ready for sunrise, and I didn't get a good night's worth of sleep due to the frigid low single-digit autumn temperatures (which were already quite warm considering the place). It was a good thing that I didn't unpack much since I needed to carry my gear back up the rocks in the darkness.
While shooting this scene, we noticed campers carrying wooden boards back up to the store. Apparently, you could get free wooden boards to line your tents with to protect yourself from all the jagged rocks, something that we did not know since we reached the place late. And yes, I can still feel those rocks digging into my inflatable mattress.

A break from all the usual vibrant and deeply saturated travel photography that I'm fond of doing for a more muted and moody scene.
This was the first location we stopped by in our trip, and while it happened to be misty during our sunrise shoot, the fog really brings out the mood for this location.
Many flocks of birds flew past the castle and I clocked in a sizable amount of frames with different compositions, making it hard to choose what positioning I liked best before settling on this. May have to process a few other frames as well!

Milford Sound, New Zealand
We were actually leaving Milford Sound when the skies suddenly cleared, so we headed back to shoot the intertidal coast. Really fortunate that we went back, for the light that afternoon was mainly flat due to overcast skies without definition.

It’s not often I see an arch inside a slot canyon but seeing a double arch view was a total treat. With the ever-changing light the back wall came alive with a scintillating yellow glow while the second arch was bathed in cool tones. Slowly the light traversed across the chamber as the walls were also bathed in glowing yellow light. Together with overlapping layers, a spectrum of colors, and multitude of textures, this chamber has all the quintessential slot canyon characteristics that show its history of being slowly carved by water and wind.
