As I anticipated earlier, Calella features a lighthouse built in 1859 and still in use. Sitting on a low hill just above Platja des Roques (which includes Cala de la Vinyeta), it is not at all an imposing presence, one of those dramatic lighthouses you often see in posters and picture postcards - it is small, clean and tidy, sporting a kind of discrete elegance. I assume that its refined look is not unrelated to the fact - not so obvious in the 19. century - that it was designed by a woman :-) (some info also here).
I was descending from the hill of Les Torretes after my first sunrise session there - from the top of the hill I could see the lighthouse wiping away the receding darkness with its bright beam of light. I was a bit disappointed, since the sunrise had been colourful, but almost cloudless and rather dull. The hills and the sea were bathed in a warm, golden light, but I felt that this was not enough to relieve my despondency. Or so I believed, until I came out of the scrub at the foot of the hill and an unexpected sight appeared before me. The golden glow of the sun was right behind the hillock of the lighthouse, and it suddenly dawned on me that choosing an appropriate point of view I would have been able to get some interesting stuff... The lantern of the lighthouse had switched off during my brief descent and the rising sun appeared to have replaced it :-)
We can think of these circumstances as a further confirmation of the UPS - the Universal Principle of Serendipity - I formulated some time ago to celebrate a beautiful photograph by my Flickr friend Rich (take the time to have a look... it is really worthwhile!). Maybe it would be useful to conceive a device by which one could have a generous share of serendipity on demand :-) - is there any mad physicist among us?
I have obtained this picture by blending an exposure bracketing by luminosity masks in the Gimp. Not an impossible task - easier than usual, actually, since I was not interested in foreground details - but I have not been able to reach one of my goals... There are some faint, delicate clouds in the dead center of the composition, somehow recalling the fancy wisps and curls of the atmosphere of Jupiter, but with a very low contrast against their surroundings. I have tried hard to enhance them, but with no success at all. My guess is that they could be more or less almost evident depending on your display :-( If someone out there has some hint or suggestion, it would be greatly appreciated :-)
I saw these two adorable little bambini sitting in this doorway and I was discretely trying to take a photo of them when all of a sudden their Nonna appeared (see pic in comments - also clickable).
At first I thought she was going to tell me to stop but she motioned for the kids to move into the doorway and encouraged them to have their photo taken by me. I don't know why I was worried, as the Italians love having their photo taken . . . well except for this little boy.

For many years I remember seeing Robinsons Shaft in the middle of an industrial patch of wasteland , it was owned by the National Trust then and mothballed . Now it is in the centre of Heartlands .
Robinson’s Shaft is the living soul and epicentre of Heartlands. Located at Pool in Cornwall, it’s one of the most important mining sites in the country.
It forms a part of one of the ten discrete landscapes that make up the Cornwall and West Devon Mining Landscape World Heritage Site and is home to a number of Grade II listed buildings.
So what makes this particular mining site so special? Well, it closed as recently as 1996 so it has retained more of its historic architecture and structure than any other site you see today where mining ceased much earlier. Robinson’s Engine House also holds the Crown Jewels of mining machinery – the Cornish pumping engine of 1854. This masterpiece has been kept in a remarkable state of preservation and was the last Cornish Engine to work on a Cornish Mine.
Robinson’s Shaft came to prominence around 1900-8, when it became the principal shaft of the South Crofty mine. However, it crops up on a plan from 1833 so it took nearly 70 years for it to take centre stage.
The turning point came in 1900, when they had to deepen the shaft to exploit the tin deposits in that part of the South Crofty mine. This involved a series of colossal engineering feats. The first of which was the construction of a winding engine, finished by 1901. Next came the installation of a pumping engine, which started in 1903. They then began the usual act of building the engine house and engine in tandem. By 1908, they’d completed the pumping engine, which allowed the shaft to be sunk to 205 fathoms. By 1910, they could mine to 238 fathoms, that’s 1428 feet or 435 metres - higher than Brown Willy, the highest point in Cornwall.
With the pumping-engine in place, the rest of the development around the shaft proceeded over the following 3-4 years. The layout was dictated by the way the different functions served the shaft, so what might appear to be a random cluster was in fact a highly organised working entity. The other early development at the shaft was the introduction of electric power, which astonishingly, seems to have taken place as early as 1910-11.
By 1967 the South Crofty mine had been reconfigured, so that the shaft at Robinson’s was used for lifting men and equipment, whilst ore was lifted at the nearby new Cook’s Shaft. The result of the changes of the 50s and 60s is that the site as seen today is essentially the product of two phases: its original development in 1900-11, when it became the major shaft in the South Crofty complex with all the typical functions of a tin mining site, and its modernisation in 1955-65 when it was adapted to play a subsidiary role in that complex.
The pumping engine at Robinson’s Shaft is a gloriously well-preserved example of a Cornish engine. It worked at this site between 1903 and 1955.
The engine was designed by Captain Samuel Grose, a pupil of Richard Trevithick, and was built by Sandys Vivian and Co. at the Copperhouse Foundry, one of the two major engineering works at Hayle. Apart from its state of preservation, and the fact that it continued to work until the 1950s, another claim to fame of this engine is that it experienced being moved no less than four times:
first erected at the Wheal Alfred mine near Hayle, where it worked 1855-64
moved to Wheal Abraham near Crowan, when it worked 1865-75
after a period of idleness moved to Tregurtha Downs mine near Marazion, where it worked 1883-95/1899- 1902 (the gap being because of the collapse of tin pieces in the mid-1890s)
re-erected for the final time at Robinson’s Shaft in 1903
If you think of shifting a house, bricks, mortar and all, you might begin to understand the complexity of this operation. Despite all these moves the engine as seen today is essentially as it was first built in 1854-5
Robinson’s Engine stopped working at 1.15pm on 1 May 1955, the last Cornish Engine to work on a Cornish Mine.
Robinson’s Engine is currently undergoing more restoration work (it’s a bit like painting the Forth Bridge), but you can still go on guided tours to see this magnificent engine and talk to our restoration team about the processes involved along with all the blood, sweat and tears. Once restored, the engine will run again using a hydraulic system. We believe in protecting the environment and we use renewable energy across Heartlands, so for now, the engine will not be run on steam.

In Papua New Guinea, there are more than more than 850 discrete spoken languages, and until recently, none of them were written down. Even today, adult literacy sits at less than 62%. In a historically nonliterate society with more than 7000 diverse cultural groups, one of the most popular means of education has been through costume, song, and dance.
Which is part of what makes sing sings so important.

Dingy Skipper / erynnis tages. Derbyshire. 18/05/16.
These tiny, moth-like butterflies are far from dingy in my opinion. Look at them closely and they have the most beautiful subtle greyish-brown / cream markings. There is a small colony on a brownfield site close to my home and I've been seeing them on the wing for the last 10 days.
On a mostly wet day there was a break in the weather and an opportunity to walk the dogs again locally. I took my smaller camera with macro lens on impulse, not even thinking about butterflies - (more about wildflowers, raindrops and bokehs)!
At the waste ground we mooched about slowly and in one particular spot I noticed this little beauty launch itself from ground level and eventually land on the seed head.
A stealthy approach and slow drop to the (wet) ground had me laying right beside it! Couldn't believe my luck and with camera gently raised I started to make images, praying the dogs didn't come nosing over to investigate. I need not have worried...they didn't and the DS was ultra confiding. After firing off many shots I dared to shift position and view it from different angles - still it sat there, unbelievable. I am sure that the weather conditions actually helped with its lethargy although it did fly again and landed on a twig closer to the ground.
I wish I had changed camera settings in order to get sharp focus on the whole of the subject but I clean forgot to :-(
However, what I have achieved are some close, detailed and relatively sharp head shots. I hope you enjoy looking at the cute little hairy face and big eyes as much as I do.
We stayed on our Norfolk trip in the pretty village of Brimham, ten minutes from the small port town of Wells
Some of the towns along this coast bear the "next to" tag, no doubt recognising that the silting of the flat marshy flats over the centuries means that they are no longer strictly "on" the sea.
Wells though is still a working port alongside a thriving (but discrete) holiday industry.
Another tantalizing view of the Grand Tetons between storms, still discretely veiled in cloud for modesty's sake. I like to think they were named by the french-speaking Iroquois, as it seems such an apt, if somewhat risque name. However, it might be they were named after the Teton-Sioux tribe, though it's not clear where the grand came from with this theory.
Best to be viewed in large size format.

Cactus galactique : Le cactus qui « touche » la Voie lactée
Dans la Vallée des Cactus, près de San Pedro de Atacama au Chili, un cactus géant se dresse sur la pente rocailleuse du canyon de Guatín. Haut d’environ cinq mètres, il domine un terrain irrégulier composé de ravines, de pierriers et de pentes abruptes, caractéristiques de cette oasis isolée où se rejoignent les eaux des rivières Puritama et Purifica. À l’arrière-plan, plusieurs autres cactus, plus petits ou plus jeunes, complètent le paysage.
Certains cactus ont plusieurs centaines d’années, et certains géants dépassent les 800 ans. Ils peuvent atteindre 8 à 9 mètres et croissent très lentement, à raison d’environ 0,9 cm par an. On dit souvent dans la région : « Ces cactus étaient déjà là quand les Incas marchaient dans la vallée. » De nombreux guides atacameños demandent discrètement à leurs visiteurs de ne pas toucher les cactus : au-delà de la dangerosité de leurs épines, les grands cardones sont considérés comme les « gardiens de la vallée », symboles de protection et de longévité.
Malgré la beauté saisissante du lieu, la zone reste difficile d’accès : éboulis, reliefs accidentés et petits cactus hérissés d’aiguilles acérées peuvent surprendre le visiteur.
L’idée de cette composition photographique était de positionner le cactus de manière à ce qu’il pointe exactement vers Antares et la région de Rho Ophiuchi, un ensemble de nuages sombres et de nébuleuses aux teintes jaunes et bleutées.
Le bulbe central de la Voie lactée, visible ici au centre, est la zone la plus brillante de notre galaxie, riche de milliers d’étoiles, de poussières interstellaires et de nébuleuses emblématiques, telles que la Lagune — un vaste nuage d’hydrogène où naissent de jeunes étoiles — ainsi que le Nuage du Sagittaire, une région extrêmement dense en étoiles et en gaz.
Après la publication de cette image, plusieurs retours amusés sont revenus de la part des observateurs. Certains y voient, avec une évidence presque désarmante, le doigt lumineux d’E.T., le célèbre extraterrestre du film de Steven Spielberg, comme si le cactus tendait la main vers les étoiles pour « rentrer à la maison ». D’autres, avec un tout autre regard, y distinguent un geste plus impertinent, évoquant un doigt d’honneur pointé vers la galaxie.
Pour ma part, cette scène m’évoque plutôt, de façon discrète, le geste de la Création d’Adam peint par Michel-Ange. La pointe du cactus semble effleurer la région d’Antares et les nuages de poussière qui l’entourent, comme si un lien ténu reliait la terre au ciel. Ces interprétations contrastées relèvent bien sûr de la paréidolie — cette tendance naturelle de notre cerveau à reconnaître des formes familières dans des structures complexes ou aléatoires. Elles témoignent surtout de la capacité des images astronomiques et des paysages désertiques à stimuler l’imaginaire de chacun, offrant autant de lectures possibles qu’il existe de spectateurs.

EN : Galactic Cactus: The cactus that “touches” the Milky Way
In the Cactus Valley near San Pedro de Atacama in Chile, a giant cactus stands on the rocky slope of the Guatín canyon. About five meters tall, it overlooks an uneven terrain of gullies, scree, and steep inclines, typical of this isolated oasis where the waters of the Puritama and Purifica rivers meet. In the background, several other cacti — smaller or younger — complete the landscape.
Some of these cacti are hundreds of years old, and the largest specimens exceed 800 years. They can reach 8 to 9 meters in height and grow extremely slowly, at a rate of about 0.9 cm per year. In the region, people often say: “These cacti were already here when the Incas walked through the valley.” Many Atacameño guides gently ask visitors not to touch them: beyond the danger of their spines, the great cardones are considered the “guardians of the valley,” symbols of protection and longevity.
Despite the breathtaking beauty of the place, the area remains difficult to access: rockfalls, uneven ground, and small cacti bristling with sharp needles can easily catch visitors off guard.
The idea behind this photographic composition was to position the cactus so that it points directly toward Antares and the Rho Ophiuchi region — a complex of dark clouds and nebulae with yellowish and bluish hues.
The central bulge of the Milky Way, visible here in the middle of the frame, is the brightest region of our galaxy, rich with thousands of stars, interstellar dust, and iconic nebulae such as the Lagoon — a vast cloud of hydrogen where young stars are born — as well as the Sagittarius Star Cloud, an extremely dense area filled with stars and gas.
After sharing the image, many viewers sent back amused reactions. Some instantly saw the glowing finger of E.T., the famous extraterrestrial from Steven Spielberg’s film, as if the cactus were reaching toward the stars to “go home.” Others, with a different sense of humor, perceived a more impertinent gesture pointing at the galaxy.
As for me, the scene subtly brings to mind the gesture from Michelangelo’s Creation of Adam. The tip of the cactus seems to brush against the region of Antares and its surrounding dust clouds, as though a delicate thread were momentarily linking earth and sky. These contrasting interpretations are, of course, examples of pareidolia — our mind’s natural tendency to recognize familiar shapes in complex or random patterns. Above all, they highlight how astronomical images and desert landscapes can spark the imagination, offering as many possible readings as there are viewers.

Madonna di Campiglio, Pearl of the Dolomites,set inside the lush Val Rendena, the Brenta Dolomites lie to its east, while the Adamello and Presanella groups lie to its west.
Set at 4,921 feet of altitude, Madonna di Campiglio is both discrete and elegant, and among the most imporant skiing hubs in the entire Alpine Arc.
The Dolomites are a mountain range located in northeastern Italy. They form a part of the Southern Limestone Alps and extend from the River Adige in the west to the Piave Valley (Pieve di Cadore) in the east. The northern and southern borders are defined by the Puster Valley and the Sugana Valley (Italian: Valsugana). The Dolomites are nearly equally shared between the provinces of Belluno, South Tyrol and Trentino.
The Dolomites, also known as the "Pale Mountains", take their name from the carbonate rock dolomite, itself named for 18th-century French mineralogist Déodat Gratet de Dolomieu (1750–1801), who was the first to describe the mineral.
American Oystercatcher
The American Oystercatchers are a group of waders forming the family Haematopodidae, which has a single genus, Haematopus. They are found on coasts worldwide apart from the Polar Regions and some tropical regions of Africa and South East Asia. The exception to this is the Eurasian Oystercatcher and the South Island Oystercatcher, both of which breed inland, far inland in some cases. In the past there has been a great deal of confusion as to the species limits, with discrete populations of all black oystercatchers being afforded specific status but pied oystercatchers being considered one single species.
The name Oystercatcher was coined by Mark Catesby in 1731 as a common name for the North American species H. Palliatus, described as eating oysters. Yarrell in 1843 established this as the preferred term, replacing the older name Sea Pie.

White Letter Hairstreak / satyrium w-album. Cloud Wood, Leicestershire. 10/07/18.
‘HEAD DOWN’
This gorgeous White Letter Hairstreak was taking the business of feeding very seriously!
Head down, tiny little hindwing ‘tails’ up, it probed deep into the bramble flower for nectar.
I remember it was a swelteringly hot afternoon and the bramble was in full sunlight, so I was surprised at how the butterfly tolerated the conditions. Also, by how lethargic and sparing in its movement from flower to flower generally. My usual perception of butterflies in high temperatures is that they either become hyper-active or else, retreat into shade.

🇫🇷 Toiles au cœur du fourré de prunelliers
Dans ce 🌿fourré 🌿de prunelliers, la rosée de septembre révèle les toiles des araignées Linyphiidae, qui sont de discrètes tisseuses de nappes soyeuses. Ces araignées jouent un rôle important de régulation des populations d’insectes, en contrôlant notamment les petits diptères et pucerons qui abondent dans ce type de milieu. Le fourré de prunelliers se caractérise par sa densité, offrant ainsi un refuge à une grande diversité d’oiseaux, d’insectes et de micromammifères, contribuant ainsi à un écosystème riche en interactions.
J’ai saisi cette image en profitant du contre-jour du soleil levant qui rendait visibles les fils perlés de rosée.

🇬🇧 Webs in the heart of the blackthorn thicket
In this blackthorn 🌿thicket🌿, the September dew reveals the webs of Linyphiidae spiders, discreet weavers of delicate sheet webs. These spiders play a key role in regulating insect populations, especially small flies and aphids that thrive in such environments. The blackthorn thicket is characterized by its density, providing shelter for a wide range of birds, insects, and small mammals, thus supporting a highly interactive ecosystem.
I captured this image by using the backlight of the rising sun that highlighted the dew-covered threads.

Had this boulder on the Moon rolled just 250 feet more, it might have plopped neatly into a crater.
This image shows a small portion of the rim of Antoniadi crater on the far side of the Moon.
Sometimes, material moves down the slope rapidly in discrete chunks. Running from the outcrops to the rim of the partially buried crater is a track etched by a rolling boulder bigger than a bus. Perhaps a moonquake shook it loose. The boulder bounced and rolled toward the partially buried crater, plowing a path that is still visible through the loose material of the slope. When it reached the rim of the partially erased crater, its path curved and it slowed to a stop.
This image was captured by NASA's Lunar Reconnaissance Orbiter Camera, or LROC, a system of three cameras mounted on the Lunar Reconnaissance Orbiter (LRO) that capture high resolution images of the lunar surface.

Looking through the rails of clothing in the hope of a bargain.
I don't just go straight to the fitting rooms, there's a long and careful selection of merchandise first, but I get very shy taking photos on the sales floor. It's so much more discrete in a changing room. Today I was bold enough to snap a few pics in big mirrors, right out in the open.
