The pupil is the sphere that is located in the center of the iris of the eye and that controls the amount of light that enters the eye. It appears black because most of the light entering the pupil is absorbed by the tissues inside the eye. In optical terms, the anatomical pupil is the eye's aperture and the iris is the aperture stop. The image of the pupil as seen from outside the eye is the entrance pupil, which does not exactly correspond to the location and size of the physical pupil because it is magnified by the cornea. On the inner edge lies a prominent structure, the collarette, marking the junction of the embryonic pupillary membrane covering the embryonic pupil.

This shot was taken at Four Winds, just off the Tavistock to Princetown road on Dartmoor. There is now a car park on the far side of the stone enclosure. But many years ago there was a local school there. The stone enclosure seems to have been used as the playground.

The school was attended by the children of families working in local quarries and agriculture. Foggintor School opened in 1914 and at one point had over 80 pupils. But as employment opportunities declined so too did the size of the school roll. The school finally closed down in July 1936 when the decline in the quarry industry at Merrivale and elsewhere reduced the number of families in the area. The school buildings gradually crumbled away over the years but were not finally demolished until the 1960s.

Having seen old photos of the school I was interested to see that it was purpose-built in brick. I suspect this substantial stone enclosure could be a much earlier structure that was taken over and used by the school as a playground, though I have not been able to find any confirmation.

Check out how different the pupils are ...

Just like the moon light through a split, you came in throught my pupils, and like that I started loving you, day by day. Without laws, without schedules. And like that you started to wake me up, from every dream where you appeared.

And no one was searching for it, and noone planned it like this, but in our destiny was set that you belonged to me. And noone would bet that I would be so happy, but cupid had mercy on me.

Like the rain in the middle of the desert, you wet my heart with faith, drawning my fears. Like a sweet voice in the silence, we fell in love, real love. ~Reyli Barba

Street in the old town of Mdina at Malta with the pupils in the history lesson.

Mdina called also "Silent City" was founded as Maleth in around the 8th century BC by Phoenician settlers, and was later renamed Melite by the Romans. Ancient Melite was larger than present-day Mdina, and it was reduced to its present size during the Byzantine or Arab occupation of Malta. During the latter period, the city adopted its present name, which derives from the Arabic word medina. The city remained the capital of Malta throughout the Middle Ages, until the arrival of the Order of St. John in 1530, when Birgu became the administrative centre of the island. Mdina experienced a period of decline over the following centuries, although it saw a revival in the early 18th century. At this point, it acquired several Baroque features, although it did not lose its medieval character.

More yellow, please. OK, maybe not pinpoint, but much smaller pupils than I usually see on Saw-whet Owls because they are usually in the shadows.

Thanks wife for letting me capture your beautiful eyes.

The creature in the image is a gecko, which is a type of lizard. Specifically, it looks like a species of gecko known for its ability to blend into its surroundings, possibly a leaf-tailed gecko or a similar species that has developed camouflage to avoid predators. Geckos are known for their distinctive eyes with vertical pupils and their ability to cling to various surfaces due to specialized toe pads. -- Grok2 mini

St Albans Boys School. Pupils leaving including girls who join the boys in the sixth form.

This is the Abbey Gateway adjacent to St Albans School. St Albans is my home town and my son went to this school. It was founded within St Albans Abbey by Abbot Wulsin in 948 and is purported to be the oldest school in the country.

This double arch really gives the impression of a giant robot helmet.

the idea was to take a photo of my eyes after returning from the eye clinic. my pupils were wide open. they weren't as wide open when i finally got around to taking the picture and the camera was not set right for the first shot. i like it because i dont look as fat as i actually am.

now i have altered the photo

The common starling (Sturnus vulgaris), also known as the European starling, or in the British Isles just the starling, is a medium-sized passerine bird in the starling family, Sturnidae. It is about 20 cm (8 in) long and has glossy black plumage with a metallic sheen, which is speckled with white at some times of year. The legs are pink and the bill is black in winter and yellow in summer; young birds have browner plumage than the adults. It is a noisy bird, especially in communal roosts and other gregarious situations, with an unmusical but varied song. Its gift for mimicry has been noted in literature including the Mabinogion and the works of Pliny the Elder and William Shakespeare.

The common starling has about a dozen subspecies breeding in open habitats across its native range in temperate Europe and western Asia, and it has been introduced to Australia, New Zealand, Canada, United States, Mexico, Peru, Argentina, the Falkland Islands, Brazil, Chile, Uruguay, South Africa and Fiji. This bird is resident in southern and western Europe and southwestern Asia, while northeastern populations migrate south and west in winter within the breeding range and also further south to Iberia and North Africa. The common starling builds an untidy nest in a natural or artificial cavity in which four or five glossy, pale blue eggs are laid. These take two weeks to hatch and the young remain in the nest for another three weeks. There are normally one or two breeding attempts each year. This species is omnivorous, taking a wide range of invertebrates, as well as seeds and fruit. It is hunted by various mammals and birds of prey, and is host to a range of external and internal parasites.

Large flocks typical of this species can be beneficial to agriculture by controlling invertebrate pests; however, starlings can also be pests themselves when they feed on fruit and sprouting crops. Common starlings may also be a nuisance through the noise and mess caused by their large urban roosts. Introduced populations in particular have been subjected to a range of controls, including culling, but these have had limited success except in preventing the colonisation of Western Australia. The species has declined in numbers in parts of northern and western Europe since the 1980s due to fewer grassland invertebrates being available as food for growing chicks. Despite this, its huge global population is not thought to be declining significantly, so the common starling is classified as being of least concern by the International Union for Conservation of Nature.

The common starling is 19–23 cm (7.5–9.1 in) long, with a wingspan of 31–44 cm (12–17 in) and a weight of 58–101 g (2.0–3.6 oz). Among standard measurements, the wing chord is 11.8 to 13.8 cm (4.6 to 5.4 in), the tail is 5.8 to 6.8 cm (2.3 to 2.7 in), the culmen is 2.5 to 3.2 cm (0.98 to 1.26 in) and the tarsus is 2.7 to 3.2 cm The plumage is iridescent black, glossed purple or green, and spangled with white, especially in winter. The underparts of adult male common starlings are less spotted than those of adult females at a given time of year. The throat feathers of males are long and loose and are used in display while those of females are smaller and more pointed. The legs are stout and pinkish- or greyish-red. The bill is narrow and conical with a sharp tip; in the winter it is brownish-black but in summer, females have lemon yellow beaks while males have yellow bills with blue-grey bases. Moulting occurs once a year- in late summer after the breeding season has finished; the fresh feathers are prominently tipped white (breast feathers) or buff (wing and back feathers), which gives the bird a speckled appearance. The reduction in the spotting in the breeding season is achieved through the white feather tips largely wearing off. Juveniles are grey-brown and by their first winter resemble adults though often retaining some brown juvenile feathering, especially on the head. They can usually be sexed by the colour of the irises, rich brown in males, mouse-brown or grey in females. Estimating the contrast between an iris and the central always-dark pupil is 97% accurate in determining sex, rising to 98% if the length of the throat feathers is also considered. The common starling is mid-sized by both starling standards and passerine standards. It is readily distinguished from other mid-sized passerines, such as thrushes, icterids or small corvids, by its relatively short tail, sharp, blade-like bill, round-bellied shape and strong, sizeable (and rufous-coloured) legs. In flight, its strongly pointed wings and dark colouration are distinctive, while on the ground its strange, somewhat waddling gait is also characteristic. The colouring and build usually distinguish this bird from other starlings, although the closely related spotless starling may be physically distinguished by the lack of iridescent spots in adult breeding plumage.

Like most terrestrial starlings the common starling moves by walking or running, rather than hopping. Their flight is quite strong and direct; their triangular-shaped wings beat very rapidly, and periodically the birds glide for a short way without losing much height before resuming powered flight. When in a flock, the birds take off almost simultaneously, wheel and turn in unison, form a compact mass or trail off into a wispy stream, bunch up again and land in a coordinated fashion. Common starling on migration can fly at 60–80 km/h (37–50 mph) and cover up to 1,000–1,500 km (620–930 mi).

Several terrestrial starlings, including those in the genus Sturnus, have adaptations of the skull and muscles that help with feeding by probing. This adaptation is most strongly developed in the common starling (along with the spotless and white-cheeked starlings), where the protractor muscles responsible for opening the jaw are enlarged and the skull is narrow, allowing the eye to be moved forward to peer down the length of the bill. This technique involves inserting the bill into the ground and opening it as a way of searching for hidden food items. Common starlings have the physical traits that enable them to use this feeding technique, which has undoubtedly helped the species spread far and wide.

In Iberia, the western Mediterranean and northwest Africa, the common starling may be confused with the closely related spotless starling, the plumage of which, as its name implies, has a more uniform colour. At close range it can be seen that the latter has longer throat feathers, a fact particularly noticeable when it sings.

The common starling is a noisy bird. Its song consists of a wide variety of both melodic and mechanical-sounding noises as part of a ritual succession of sounds. The male is the main songster and engages in bouts of song lasting for a minute or more. Each of these typically includes four varieties of song type, which follow each other in a regular order without pause. The bout starts with a series of pure-tone whistles and these are followed by the main part of the song, a number of variable sequences that often incorporate snatches of song mimicked from other species of bird and various naturally occurring or man-made noises. The structure and simplicity of the sound mimicked is of greater importance than the frequency with which it occurs. Each sound clip is repeated several times before the bird moves on to the next. After this variable section comes a number of types of repeated clicks followed by a final burst of high-frequency song, again formed of several types. Each bird has its own repertoire with more proficient birds having a range of up to 35 variable song types and as many as 14 types of clicks.

Pretty much any sunrise is beautiful to see. But some are Amazing and some are breathtaking.

After a lot of sunrise-less morning, I managed to get a decent one. This spot was one of the best "Breakfast with a view" place I have ever had. I admit that this shot went through Lightroom before arriving here but the colors displayed here are as close to the real colors as possible.

If you go to Bryce Canyon and have only one morning, go to Inspiration Point, pack a breakfast, hope for a good weather and... Enjoy & Get inspired.

This is the "Biggin" an old mansion on the Bramham Park Estate, West Yorkshire, England..

It is a substantial house which was built on the site of the medieval Nostell Priory monks' cell. In 1842/3 the Biggin was leased to Dr. Benjamin Bentley Haigh and became Bramham College, a prestigious school for boys. The life of the college was shortlived, however, when in 1869 cholera struck and Dr. Haigh and several pupils died

All the additional buildings were demolised leaving the Biggin in its original state where it reverted to a private residence
