I took this photo several years ago in Soho (London - 2017) It seems kind of pertinent at the moment.
This morning I was very lucky to get a red sky mixed with some lovely mist. The way the light gleamed off the lingering mist really looked lovely, whirling around that particular row of trees. It was a very tough choice about whether to snooze the alarm or not but I persevered and was rewarded for once.
A cherry pip, safe on its own and intact, but if chewed or ground, the amygdalin releases cyanide when metabolised within the body.
Various plant seeds or pits contain amygdalin, which releases cyanide when metabolised, including cherries. The amounts are small, so that in general, toxicity is not seen except in cases where a combination of factors seriously exacerbates the problem. Essentially, you need a pit or seed from some fruit of a plant in the family Rosaceae, generally from Prunus genus (cherries, plums, peaches, apricots, and almonds).
Under such conditions, you can ingest enough amygdalin to kill you. However, while some cherry pits do apparently contain amygdalin at the same concentrations as bitter apricot kernels, the amount you would have to eat is considerably more than two pits. The LD50 for bitter almonds (which are also similar to cherry and apricot kernels, with ~5% amygdalin content) in rats is estimated to be a little more than 3 grams per Kg of body weight.
Conditions were just about perfect for low-flying photography last week. A break in the weather after a sudden downpour resulted in hilltop cloud & the all important humidity in the air. As a 2-ship of USAF F-15E operating from RAF Lakenheath called into the 'Roundabout', all I had to do was gaze down the valley in anticipation of the signature quarter-mile long wingtip ‘ribbons'.

Miserable conditions couple years back, same day the Bo’ness gala was operating. Those photos will pop up soonish. Break from the gala, 37s on the Edinburgh to Glasgow line with the mentor coach doing its job. Wasn’t expecting that! And now 37099 has a new front, like class 37510…..bye bye light box. Seen passing Croy
A Cliché shot of the Cocklawburn Block shaped rocks. I visited here for sunset but there was no cloud cover around, so not ideal conditions. I did try this though, and liked the glow from the sun on the rocks.
Many thanks for viewing.
Conditions were less than ideal in my neck of the woods, with a lot of pesky clouds driting across every few minutes. These were all I could sneak into the few gaps that came my way.
Although conditions at sea level were fairly benign, as we climbed up to the Old Man the wind increased to gale force so even just standing was a battle. This little lochan beneath the Old Man was only slightly sheltered, but the layer of ice beneath its surface helped to keep the water still enough to give nice reflections.
Após uma pausa na Vega de Asotín, a 1450 metros de altitude, um grupo de montanhistas retoma a exigente subida ao refúgio de Collado Jermoso, a 2064 metros, no Maciço Central dos Picos de Europa, integrado no Parque Nacional criado em 1918. O trilho, que se segue à travessia do faial de Asotín, aumenta consideravelmente em dificuldade, com um desnível positivo superior a 1200 metros em pouco mais de 5 quilómetros. O percurso avança pelo Argayo Congosto, um canal de forte inclinação que leva às proximidades do refúgio, serpenteando por terrenos calcários e pedregosos típicos desta cordilheira cantábrica, onde a vegetação alpina se intercala com campos de pedra calcária. O refúgio, também conhecido como "Diego Mella", está localizado num promontório natural sob a Torre del Llambrión, com vistas para o vale de Valdeón, servindo de base para ascensões aos picos mais altos, incluindo o Naranjo de Bulnes, numa área onde as condições meteorológicas variáveis exigem preparação adequada.
After a break in Vega de Asotín, at 1450 meters above sea level, a group of mountaineers resume the demanding climb to the refuge of Collado Jermoso, at 2064 meters, in the Central Massif of the Picos de Europa, integrated in the National Park created in 1918. The trail, which follows the crossing of the Asotín beech forest, increases considerably in difficulty, with a positive difference of more than 1200 meters in just over 5 kilometers. The route advances through the Argayo Congosto, a steeply sloping channel that leads to the vicinity of the refuge, winding through the limestone and stony terrain typical of this Cantabrian mountain range, where alpine vegetation is interspersed with limestone fields. The refuge, also known as "Diego Mella", is located on a natural promontory under the Torre del Llambrión, overlooking the Valdeón valley, serving as a base for ascents to the highest peaks, including the Naranjo de Bulnes, in an area where the variable weather conditions require adequate preparation.
Conditions on Friday night looked great for some night time photography, with a new moon and no clouds, so I headed up to Holy Island for a shoot.
The wind was causing the biggest problem so although this isn't the exact composition I wanted, it was taken huddled under the shelter of a boat so I was able to protect the camera / tripod from the wind and keep it still.

1. Conditions idéales
Lieu : Un horizon dégagé sur la mer, une plaine ou une haute altitude. Une vue sans obstacles est essentielle.
Météo : Ciel clair, air sec, sans pollution ni brume.
Moment : Quelques secondes avant que le soleil disparaisse complètement à l’horizon (coucher de soleil) ou juste avant qu’il apparaisse (lever de soleil).
Altitude : Plus vous êtes haut, plus le phénomène dure longtemps (jusqu’à 2 secondes).
Regard : Fixez l’horizon, évitez les écrans lumineux avant l’observation pour une meilleure perception.
2. Explication rapide du phénomène
La réfraction atmosphérique agit comme un prisme qui sépare la lumière du soleil.
Le rouge et l’orange plongent plus tôt sous l’horizon, tandis que le bleu et le vert restent plus longtemps visibles.
L’atmosphère diffuse le bleu, laissant parfois un éclair vert fugace juste avant la disparition du soleil.

Great idea! A practical summary with observation tips and well-chosen references will provide a clear guide for enthusiasts of the green flash.
Practical Guide to Observing the Green Flash
1. Ideal Conditions
Location: A clear horizon over the sea, a plain, or a high-altitude spot. An unobstructed view is essential.
Weather: Clear sky, dry air, no pollution or mist.
Timing: A few seconds before the sun completely disappears below the horizon (sunset) or just before it rises (sunrise).
Altitude: The higher you are, the longer the phenomenon lasts (up to 2 seconds).
Gaze: Fix your eyes on the horizon, avoid bright screens before observation for better perception.
2. Quick Explanation of the Phenomenon
Atmospheric refraction acts like a prism, splitting the sunlight into different colors.
Red and orange sink below the horizon first, while blue and green remain visible slightly longer.
The atmosphere scatters blue light, sometimes leaving a fleeting green flash just before the sun disappears.

It was so cold when this shot was taken that my lens was coated with ice, requiring a minute or so to remove it between frames. I couldn't breathe whilst cleaning it because my breath would turn to ice on the lens, meaning I had to start the cleaning process over again. Yep, pretty tedious.
All the while the four blokes were patiently waiting for me to take the shot. Thanks for your help with this image Robert Gaunt, Jake Anderson, Brendan Goodger, and Gavin Owen. Some pretty epic shooting conditions on an afternoon/evening that's hard to forget.
This moonlit scene was captured with a Sony A7R combined with a Samyang 14mm f/2.8 lens.

due to the perfect climate conditions, there are so many beautiful gardens in Cornwall. Trebah Garden is a gem, situiated on Helford River
Conditions were ideal tonight for some Jupiter action! Thrilled with this grab and go shot from our back garden - hardly any breeze, clear cold skies!

The conditions were absolutely brutal to view the lunar eclipse of January 20-21, 2018. The temperature was about 10 degrees Fahrenheit while the winds were gusting to 40+ MPH. Twice my tripod blew over, fortunately without damaging the camera or lens. Despite the conditions, I was able to get a few images without too much blur or shaking! The image was made with a Canon 80D and a Canon 200 mm f/2.8L II lens using an iOptron Sky Tracker.
We’ve had a few days this winter with the right conditions to create a certain kind of magic. Cold temperatures and calm air allows the creation of soap bubbles that quickly freeze into solid orbs of frost. During the freezing process, they become something magical. View large!
Last night I spent a few hours experimenting with these. Some complex lighting was done from behind, using a narrow-beam flashlight and a Fresnel lens to place the light exactly where I wanted it. The bubble was blown just above this location and gently placed on the snow. Most of the time, bubbles will burst on impact unless you use a more hardy formula in their creation. The recipe used is:
6 parts water
2 parts liquid dish soap
1 part white corn syrup
It’s the corn syrup that thickens the bubble solution to withstand impact with the snow. It doesn’t work all the time, but when a snowflake lands intact, the game is on.
Freezing usually starts quickly, and there are two different scenarios you’re likely to encounter:
Warm bubble liquid: You can prolong the time you have to get the camera in the proper location by heating up the bubble solution in the microwave. This can give you a few extra much-needed seconds to get everything aligned, and it creates stable growth. In this scenario, the bubble will start to grow frost from the point of contact with the snow, and usually somewhere near the top of the bubble. These frost fronds will continue to grow until they reach, closing in the bubble.
Cold bubble fluid: If you’re using cold bubble fluid, right near the freezing point, you’re in for a show. Particles from your breath that are pushed inside the bubble will collide with the wall of the bubble, sometimes freezing on impact and creating nucleation points for frost. These swirl and grow around the freezing sphere almost like snowflakes, eventually freezing together. That’s what you’re seeing here. The freezing process usually has already begun by the time the snowflake has landed, and very little time is available to get the camera to the proper angle and focus point.
Like my snowflake images, this was shot entirely handheld. Speed is very important for such subjects, and a tripod only gets in the way. The entire bubble is frozen solid in a matter of seconds.
It’s amazing what falls from the sky, created by the randomness and beauty of nature… but it’s astounding what the right ingredients in the right order can create with the intent of creating something beautiful here on earth.

The foggy conditions continued across the Midwest today which meant a frosty countryside was found everywhere. I made a trip down to do some Transcon action in the snow, which I haven't done hardly at all. It was a good day, traffic was alittle slow unfortunately.
The new year resets the train counts in the coal train symbols on the BNSF. The 1st loaded train of 2021 for Rush Tower, MO, (RTR"001") for Union Electric is eastbound on the Ottumwa Sub. Here the coal train picks up speed as they roll into Mount Pleasant. At Burlington the train will get a new crew for the trip down the K-Line towards Hannibal and onto St. Louis.
The Crows seem to like to forage in the rock pools and provided a little interest to my foreground as I was waiting to see what the cloud bank would do, the horizon was well defined to show the distant ships, ( Q Pink Floyd Comfortably numb ) , Lancing beach at Sunrise.
We had fascinating conditions for night photography in Bodie on Saturday night..There were fast-moving clouds and Milky Way early on, then snow showers and moving clouds with airglow later. The snow never stuck to the ground, but it was an interesting addition to some of the photos!
Fortunately it was cold enough that for the most part, the snow wasn't sticking to our lenses.
A lack of conditions and imagination eventually brought me to the burn. I’ve taken a number of images from this point in the past so this time for a slightly different perspective I waded into the middle on a nice flat bed of rock, enough for me and my tripod. I took a couple of images and then I decided on this 16:9 to emphasise the width of the burn. Carrying a few thousand pounds of gear into a stream always has me on my toes with the focus of whatever happens I’ll get wet but not the camera. This composition was completed with no drama and decided on a up stream shot. You probably can’t make it out from this image but there is a 2 foot drop in the stream just before the first tree, with a lovely cascade. All I needed to do was make my way along the left hand bank, get under the leaning second tree using the thin ledge and position my tripod just beyond. That thin ledge skirts a sudden drop into a deep pool so it was the crux of my traverse. All was good and I took a few photos. On reversing my manoeuvre just as I passed the tree my foot slipped, of cause my camera was safely on the end of my folded tripod which I was using for balance pole and luckily the pool was only knee deep, but a good few inches over the top of my welly. Once safely on the bank the welly was off and I emptied a couple of pints of burn water back where it belongs. Not cursing any lost or damaged gear I regard this as all part of the fun and wouldn’t have it any other way.
Night sky conditions were poor last night; the new Moon was quite intrusive and great clouds of salt spray were being driven inland by the onshore nor'easter. A lot of slider movements were needed to rescue the image (single exposure). The glow at the base of the image is from the setting Moon. I've also noticed that quite strong edge coma is a feature of this lens. Antares (alpha Scorpii) sits brightly below the Milky Way; Jupiter is still doing its thing above.

if conditions had lined up right, my house ought to have received a few rays of actual direct sunshine a little after 1pm today — alas, the clouds are not cooperating, but good to know it’s possible again…

Conditions de prises de vue extrêmes, peu de luminosité des installations, pas de pied, vent, je pense que le résulat n'est pas trop mal!
Le parc est créé dans le cadre de l'exposition internationale Emscher Park. Localisé sur le site d'une ancienne sidérurgie, le parc paysager est l'un des points d'ancrage de la Route européenne de la culture industrielle et de la Route de la culture industrielle (de) de la Ruhr. Le quotidien britannique The Guardian classe le parc parmi les dix meilleurs parcs urbains du monde aux côtés du High Line (New York), des Buttes-Chaumont (Paris), de Hampstead Heath (Londres) et du Parc Güell (Barcelone)1. En 2016, le parc accueille 1 019 391 visiteurs et plus de 800 événements.
Les installations industrielles sont mises en scène tous les jours à la tombée de la nuit jusqu'à 1 h avec un éclairage coloré par Jonathan Park.
Extreme shooting conditions, little light from the installations, no feet, wind, I think the result isn't too bad!

The conditions couldn't have been better to capture some sea smoke from Fort Preble in South Portland. By climbing up onto the old battlements, I was able to get a clear line of sight to Portland Head Light. I used a 400mm lens to compress the scene and draw in the lighthouse. This also made it possible to have a nice dark background because of the cloud bank that was low on the horizon.
Had some time and better conditions today to try some long exposures at some waterfalls in Glenmoriston, that soon after, run into Loch Ness, Scotland, UK.

well, the snow is almost all gone (we have icy rain instead), and the winds are down a bit but still racing across the landscape and whipping up mini-waterspouts on the fjord (so George is still unhappy) — still a bunch of storm to get through
Not the best conditions this morning, the sunrise never quite materialised, overtaken by fast moving low cloud. Still after a bit of a famine recently and a general lack of inspiration it turned out to be a helpful kick start to getting back in the groove.......

The conditions look fairly extreme in this image of the route to the summit of Mam Tor, but in fact it was actually quite pleasant. There was only the mildest of breezes and the temperature hovered around the freezing mark. This made it much more pleasant compared with my visit on 28th December 2017, when there was a gale force wind and the whole hill was covered in sheet ice. This image shows some photographers near the top of the hill, making the most of the snowy conditions.
Near whiteout conditions were coming to an end as I drove into Manotick to complete some errands. Prior to this shot, it was near zero visibility, and a white knuckle drive.
In poor snowy weather conditions, DB locomotive 101 004 was photographed in Pfaarwerfen working EC216 from Graz to Saarbrucken on IC stock pushing from the rear on the afternoon of the 3/2/18.
In dreadful conditions as the rain started and light dropped out of sight. Shame as I wanted that livery!
Conditions so good my two middle schoolers were happy to wake up early on the first day of winter break!
Kalitta putting on another great show this morning, heading back to SDF, handling seasonal volume for UPS. From an earlier post, it sounds like today might be one of the last visits of this particular aircraft for the year, I'm so happy I was finally able to catch it with Kid 1 and Kid 2!

I had every intention of going out to capture shots from the snowfall we are getting but it is snowing so hard that driving is actually a scary event. This park is just down the road from where I live and when got (only) this far, I decided not to venture much further. We have had over 8 inches, probably more like 10 now and the streets are terribly slick. My traction control kicked in more times in this little trip than its ever kicked in since I got my car 3 years ago......lol. I am not afraid to drive in snow, but there is a limit. I decided to be realistic about a photo shoot outdoors today and head back home. At least I got this shot. When the snow stops and they can catch up on plowing the roads, i will head back out. For the record, this is my 1st shot with the new lens :-)
