Comet NEOWISE (C/2020 F3) over some of the eroded hoodoo formations at Dinosaur Provincial Park, Alberta, July 14-15, 2020. A faint aurora is at right. The foreground is lit by starlight only; there was no light painting employed here.
This is a stack of 12 exposures for the ground to smooth noise, blended with a single untracked exposure of the sky, all at 20 seconds at f/2.8 and ISO 1600, all with the 35mm Canon lens and Canon 6D MkII camera. Taking lots of shots and stacking them allowed the foreground to be brightened without introducing too much noise and ugly banding artifacts the non-ISO invariant sensor of the 6D MKII is prone to. An alternative would have been to take a single very long (multi-minute) exposure at a lower ISO just for the ground, but even then stacking several would still be best.
LENR employed on all shots on this warm night to eliminate thermal noise and speckling. ON1 Dynamic Contrast filter applied to the ground. Plus some dodging and burning applied to the ground using a neutral grey layer on Overlay blend mode to better sculpt the otherwise flatly lit foreground on this dark, moonless night. The sky is lit by twilight that is perpetual in summer at this latitude of 51° N.
At first glance this captivating scene peering through wispy clouds and down onto a dune field is reminiscent of a satellite view of one of Earth’s deserts, but this is in fact a beautiful landscape on Mars.
This spectacular dune field sits in the centre of Lomonosov crater, deep in the southern hemisphere of Mars (65ºS, 351ºE). It was imaged by the CaSSIS camera on the ESA-Roscosmos ExoMars Trace Gas Orbiter (TGO) on 2 December, 2020.
At this time, southern summer was coming to an end on Mars. The image was taken as part of a campaign to track the evolution of the dune field through the end of summer and beginning of autumn, when frost would start covering the surface in this region. The crests of the dunes indicate the average wind direction, in this case, the wind comes predominantly from the bottom left to the top right of the image. To the right, darker, more basaltic rich sediments are visible. It is also in the right of the image that bright white clouds stand out against the darker sediments on the ground.
The image was released on the occasion of the five year launch anniversary of the mission.
The first five years
TGO launched from the Baikonur Cosmodrome in Kazakhstan on 14 March 2016, arriving at Mars seven months later. It spent several months aerobraking – using the top of the planet’s atmosphere to create drag and slow down – to became the first ESA spacecraft used to enter its science orbit in this way.
The mission began full science operations in April 2018 with its suite of four instruments. TGO’s NOMAD and ACS spectrometers are designed to provide the best ever inventory of the planet’s atmospheric gases yet, and have already detected a new gas – hydrogen chloride – for the first time, as well as studying processes linked to atmospheric water escape in greater detail than ever. TGO is also adding to the lively debate surrounding the presence of methane on the planet by revealing a surprising lack of the mysterious gas. The FREND instrument is mapping the distribution of hydrogen in the uppermost metre of the planet’s surface, creating a detailed map of possible water-rich oases, relevant for future exploration of Mars. The CaSSIS camera has captured more than 20 000 images documenting the surface and complementing the data returned by the other instruments to help characterise features that may be related to trace gas sources.
TGO also provides routine data relay for NASA’s landers and rovers: Opportunity (until its end of operations in 2018), Curiosity, Insight and Perseverance. It will also be the communication link for the second ESA-Roscosmos ExoMars mission, comprising the Rosalind Franklin rover and Kazachok platform, when it arrives on Mars in 2023.

I was surprised to see all of this action in the sky last night, the night sky has been quite 'uneventful' this entire winter.
ZENITAR-M2s 50mm f2 MC / 改鏡
== 右眼慢拍老鏡攝影展 < 第 7 講 > ==
冬天的寒風不是溫柔的，它以凌厲的速度擦拭大地，將楓葉搓紅如燃燒的烈焰。在這莫之能禦的自然神力中，拿著 ZENITAR-M2s 50mm f2 MC 這顆老鏡，改過鏡片排列後賦予影像更強烈的畫意風格，使楓葉不只是靜止的葉片，而是一幕北風的吶喊，一場季節的狂舞。這個畫面讓我聯想到 羅伯特·卡帕在二次大戰諾曼第登陸搶灘時的失焦系列作品，影像幾乎失焦到難以辨認，卻更具速度孤寂與生死瞬間的情緒張力，攝影從不僅只是清晰的再現，它可以承載動感、情緒與時間的脈動。
--- 使用刻意修改鏡片排列的老鏡，創造出異質的焦外畫意，使影像帶有撕裂般的張力，這種光學語言，使風中的楓葉不只是散亂的物件，而是畫布上的狂放筆觸，顯現當下的不安分，在風裡飛旋，用失焦來訴說北風的剛烈。
--- 一般而言，清晰度被視為影像品質的標準，但在表現動感時，失焦反而是一種更具張力的語言。卡帕的戰場影像、布列松的街頭紀實，甚至莫內的印象派繪畫，都在探索焦點的模糊如何強化情緒的力度。
--- 標準焦段 50mm 記錄楓葉準焦區域的細膩紋理，而 f2 的大光圈則柔化了失焦的背景，使紅葉在柔霧般的光影中顯得更加鮮活，紅色的葉片被冬風輕輕揉搓，彷彿即將燃燒出訴說不盡的光陰故事。
這場如靜似動的視覺體驗不僅與羅伯特·卡帕的戰地紀錄產生共鳴，也與印象派的筆觸哲學相互交織，焦點不再是精準的輪廓，而是流動的情緒，失焦，不只是技術上的偏離，而是攝影語言的一種自由釋放，使影像擁有更強烈的感官能沉浸其中的衝擊，如同詩句未竟之筆，讓觀賞者留下了更多想像的空間與自我闡釋未知的未知。

This eagle came in very close, filling the frame. Very high dynamic though given the clouds and lighting. I exposed this 1 stop over, and probably could have gone another half stop. The noise in the dark areas is pretty low though, and I could eliminate it if I darkened it a hair more, but I like the details here when not zoomed in. At full resolution you start to perceive a little noise ... pixel peering.
The BEST sunrise that I have seen this year.. and I have seen a few lately.

After many, many attempts at getting rolls of doubles to line up I finally got one pretty much spot on. I can't tell you how much of a relief it was to get a set of prints back from the lab that weren't misaligned with frames smack bang in the middle of each other. I shot a roll of sunsets then rewound and added a second layer during a visit to London with a couple of old friends who I snapped from down low at Old Street Underground station.

I took a quick time lapse video of the clouds today. I thought it was really neat how they were dynamically created and dissipated.
captured just around the corner from plaça espanya in palma, this image plays with geometry, contrast, and motion. the bold, repetitive patterns of the building’s facade create a striking architectural backdrop, while the zebra crossing guides the viewer’s eye to the man in motion. his casual stride and the paper in his hand add a human element to the rigid symmetry of the scene. the deep shadows and strong light evoke the sharp, sunny afternoons of mallorca, blending minimalism and street photography into a moment that feels both dynamic and timeless.

I've taken shots of this tree at a few different times throughout the year, but I think that this is by far my favorite one! I did a bit of Orton to this one as well, and I really like the result!
Well, we are suuposed to get 3 more inches tonight, so the total will be pushing 40" total of snow! Just crazy!
Thanks for stopping by my friends!
I don't mind invitations, but please no big, shiny, flashing, glitter graphics, they will be deleted. Also, please contact me if you would like to use my pictures for any reason. Thanks!

When I saw this I wondered who was having sewer problems and then it dawned on me that I have a backflow valve on my sprinkler system and I pay the water people yearly for it to be checked.. I never saw anybody but then I was more interested in getting the picture than looking for people... LOL!! Happy Truck Thursday, Everybody!!!!!!
