One of the most rewarding joys of landscape photography for me is way it catalyzes calming, almost elementally humbling feelings. When in such locations as this shot, (Flambrough head at low tide) I feel profoundly immersed in nature and genuinely emotionally centred. It just feels ‘so right’ on many different levels. (Sorry to sound a bit like a new age eco warier so early in this post, but even the most emotionally hard street photographers amongst you, should just try at least once placing yourself in such environments to see how it feels...)
Anyway, not only does this environment help me feel calm and centred, but the very act of photographing it, offers the added caveat of immense exhilaration. Putting oneself into this dynamic environment, at dusk, at the very edge of acceptable safety, dodging waves, wading just that bit too far out and second guessing the incoming tide, has the stimulating ability to sharpen the mind. Let’s not forget dealing with the anxious feelings knowing that you’re mobile is out of signal and any form of human insurance left hours ago. Let’s not stress either, about the long slippery walk over wet seaweed encrusted rocks back to the car in the dark, (unless of course you slip within the tidal range), but your most probably going to end up alive in the morning.
But just reflecting for a moment, I’m sure that I wouldn’t make the considerably arduous effort and experience the feelings of excitement and anxiety associated with pushing oneself to the edge of acceptable risk, if I wasn’t doing it for a photographic reason. In part, it’s the very risk taking itself that inspires the deep humbling feelings of connectivity with the natural surroundings. I wouldn’t be doing this, (or experiencing what I am) if it were not for the fact that I am attempting to record the feeling photographically. Yes I could connect with my inner calma and tune my sharks in other ways and do yoga overlooking a setting sun to really connect with the oneness of nature, (believe me I’ve seen people doing it) but I wouldn’t be pushing myself towards feeling this unique type of exhilaration. It would be a little strange to be there at dusk sometimes a little too deep in choppy seas, really observing the natural rhythms of nature without having a reason for looking. The desire to seek out this in our environment, even with camera gear strapped to my back, has actually helped catalyse a deeper feel a oneness with the environment. It’s as close to a meditation experience I can admit to here in public. Anyway as I said, there are many reasons for my photographic obsessing, but in part anyway this exhilaration is often overlooked as one of those justifications.
Now turning to this shot in greater depth, the range of subtle colours generated in this location amazed me. Flambrough is fundamentally white chalk cliffs and this does wondrous things to the reflected and refracted light, especially in the water. Light just bounces around, even when there isn’t much around, creating much more depth and range of colours. With this particular evening the sunset didn’t really materialise, (shame as the previous evening there was a speculator dramatic light show but for the sake of my marriage, I only saw it through my peripheral vision) but in a gritted teeth mature way, I’m kind of glad that I ended up here on this evening. It offered me the opportunity to appreciate the subtler more calming experiences. Something that as I get older I’m enjoying much more, who knows I may even put the camera on timed release next time and adopt the lotus position to record my tree hugging development.

There's a story here. One of the values of visiting the same location very often is that the mind -- the subconscious perhaps -- makes a map of sorts. When one sees something which is new to the area, out of place, disjointed, the mind notices.
Walking through the upper woods, mostly watching the tree tops for the Great Horned Owl, my peripheral vision noted something out of place...at a distance. I did a bit of a double take, looked through the lens, and realized I was seeing a Red-Tail sitting on a log. I shot some frames; the motor drive sound spooked it, and I kept shooting as it lifted off. I was SO fortunate.
This is, I'm reliably told, a juvenile Krider's (pale morph) Red-Tailed Hawk.
You can see the hawk bump on the log which peripheral vision noticed in the distance, in the top comment box photo below.
Mercantour National Park (French: Parc national du Mercantour) is one of the ten national parks of France. Since it was created in 1979, the Mercantour Park has proven popular, with 800,000 visitors every year enjoying the 600 km of marked footpaths and visiting its villages.
The protected area covers some 685 km², consisting of a central uninhabited zone comprising seven valleys - Roya, Bévéra, Vésubie, Tinée, Haut Var/Cians (in the Alpes-Maritimes) plus Verdon and Ubaye (in the Alpes-de-Haute-Provence) - and a peripheral zone comprising 28 villages. Many of them are perched villages,such as Belvédère at the entrance to the spectacular Gordolasque valley, concealing great architectural riches (numerous churches decorated with murals and altar pieces by primitive Niçois painters). More than 150 rural sites are located within the Park. Around Mont Bégo there are petroglyphs pecked out on schist and granite faces. They have been dated from the late Neolithic and Bronze Ages.
In the heart of this setting of vertiginous summits (including Mont Gélas (obscured by clouds here), the highest point in the Maritime Alps at 3,143 m), lies a gem listed as a Historical Monument, the famous Vallée des Merveilles (out of view to the upper right), the aptly named "valley of marvels". At the foot of Mont Bégo, climbers can admire some 37,000 petroglyphs dating back to the Bronze Age, representing weapons, cattle and human figures that are sometimes very mysterious. A less challenging destination is the Musée des Merveilles at Tende.
In addition to the holm oak, the Mediterranean olive tree, rhododendrons, firs, spruces, swiss pines and above all larches, the Mercantour is also endowed with more than 2,000 species of flowering plants, 200 of which are very rare: edelweiss and martagon lily are the best known, but there is also saxifrage with multiple flowers, houseleek, moss campion and gentian offering a multi-coloured palette in the spring. The Mercantour is the site of a large-scale All Taxa Biodiversity Inventory and Monitoring programme to identify all its living species, organised by the European Distributed Institute of Taxonomy.
Walkers may easily glimpse a chamois, several thousand of which live in the park and may often hear the whistling of marmots. The ermine is rarer (and more furtive), as is the ibex and the mouflon, although with a little luck you may be able to observe them during the coolest parts of the day in the summer. There is a tremendous variety of wildlife in the Mercantour: Red Deer and Roe Deer in the undergrowth, hares and wild boars, partridges, Golden Eagles and Buzzards, numerous species of butterflies and even about 50 Italian Wolves (which migrated there at the beginning of the nineties). A Wolves Centre welcomes visitors in Saint-Martin-Vésubie.
The Maritime Alps are a mountain range in the southwestern part of the Alps. They form the border between the French region of Provence-Alpes-Côte d'Azur and the Italian regions of Piedmont and Liguria. They are the southernmost part of the Alps.
Administratively the range is divided between the Italian provinces of Cuneo and Imperia (eastern slopes) and the French department of Alpes-Maritimes (western slopes).
The Maritime Alps are drained by the rivers Roya, Var and Verdon and their tributaries on the French side; by the Stura di Demonte and other tributaries of the Tanaro and Po on the Italian side. There are many attractive perched villages, such as Belvédère at the entrance to the spectacular Gordolasque valley, some concealing unexpected architectural riches (for example in the south there are numerous churches decorated with murals and altar pieces by primitive Niçois painters).
Parc national du Mercantour est l'un des dix parcs nationaux de France. Depuis sa création en 1979, le Parc du Mercantour a prouvé populaire, avec 800 000 visiteurs chaque année profiter des 600 km de sentiers balisés et visiter ses villages.
La zone protégée couvre environ 685 km², composé d'une zone inhabitée central comprenant sept vallées de la Roya -, la Bévéra, Vésubie, Tinée, Haut Var / Cians (dans les Alpes-Maritimes), plus Verdon et l'Ubaye (dans les Alpes-de-Haute- Provence) - et une zone périphérique comprenant 28 villages. Beaucoup d'entre eux sont perchés les villages, comme Belvédère à l'entrée de la vallée de la Gordolasque spectaculaire, cachant de grandes richesses architecturales (nombreuses églises décorées de fresques et retables de peintres primitifs niçois). Plus de 150 sites ruraux sont situés dans le parc. Autour du Mont Bégo il ya pétroglyphes piquetées sur schiste et de granit visages. Ils ont été datés de la fin du Néolithique et l'Age de Bronze.
Au cœur de ce cadre de sommets vertigineux (y compris Mont Gélas (obscurci par les nuages ici), le point le plus élevé dans les Alpes Maritimes à 3143 m), se trouve un joyau classé Monument Historique, la célèbre Vallée des Merveilles (hors de la vue en haut à droite), la «vallée des merveilles» porte bien son nom. Au pied du Mont Bégo, les grimpeurs peuvent admirer quelques 37 000 pétroglyphes datant de l'âge du bronze, représentant des armes, des bovins et des figures humaines qui sont parfois très mystérieuse. Une destination moins difficile est le musée des Merveilles de Tende à.
En plus le chêne vert, l'olivier méditerranéen, rhododendrons, sapins, épicéas, pins suisses et surtout les mélèzes, le Mercantour est également doté de plus de 2000 espèces de plantes à fleurs, dont 200 sont très rares: edelweiss et lys martagon sont les plus connus, mais il est aussi saxifrage à fleurs multiples, joubarbe, silène acaule et gentiane offrant une palette multicolore au printemps. Le Mercantour est le site d'une grande échelle par les taxons biodiversité programme d'inventaire et de surveillance pour identifier tous ses espèces vivantes, organisé par l'Institut européen de Taxonomie.
Les marcheurs peuvent facilement apercevoir un chamois, plusieurs milliers de qui vivent dans le parc et peut souvent entendre le sifflement des marmottes. L'hermine est plus rare (et plus furtif), tout comme le bouquetin et le mouflon, mais avec un peu de chance vous pourrez peut-être de les observer pendant les heures les plus fraîches de la journée en été. Il ya une grande variété de la faune dans le Mercantour: Red Deer et de chevreuils dans le sous-bois, les lièvres et les sangliers, perdrix, Golden Eagles et des buses, de nombreuses espèces de papillons et même environ 50 loups italiens (qui ont migré là au début de les années nonante). Un Centre des Loups accueille les visiteurs à Saint-Martin-Vésubie.
Les Alpes-Maritimes sont une chaîne de montagnes dans la partie sud-ouest des Alpes. Ils forment la frontière entre la région française de Provence-Alpes-Côte d'Azur et les régions italiennes du Piémont et de la Ligurie. Ils sont la partie la plus au sud des Alpes.
Administrativement la gamme est divisée entre les provinces italiennes de (pentes orientales) Cuneo et Imperia et du département français des Alpes-Maritimes (versant ouest).
Les Alpes Maritimes sont drainés par les rivières de la Roya, Var et du Verdon et leurs affluents du côté français; par la Stura di Demonte et autres affluents du Tanaro et le Pô sur le versant italien. Il ya beaucoup de villages perchés attrayantes, comme le Belvédère à l'entrée de la vallée de la Gordolasque spectaculaire, quelques richesses architecturales dissimulant inattendus (par exemple dans le sud, il ya de nombreuses églises décorées de fresques et retables de peintres primitifs niçois).

While sitting in my blind watching for Wood Duck activity there was often a lot of peripheral activity that was equally exciting. One day in April a Great Blue Heron came out on what I call my "stage" (my range of visibility) and began hunting. Almost immediately it caught this Catfish and began maneuvering the fish in preparation to swallow it whole. After several minutes the heron finally had the fish in its throat but the catfish got stuck, probably hooked by one of the barbs. The heron gagged a bit and finally coughed the fish back out again, readjusted and then swallowed it in one swift move. I did see Wood Ducks that day, but it was this Great Blue Heron and its catfish sidekick that stole the show. April 18, 2015

SpO2 Defined as Peripheral Oxygen Saturation
incenter.medical.philips.com/doclib/enc/fetch/586262/5864...
Introduction
The body's need for oxygen is certain. Its availability at a tissue level is some- times in doubt. Blood gas measurements provide critical information regard- ing oxygenation, ventilation, and acid-base status.
However, these measurements only provide a snapshot of the patient's condition taken at the time that the blood sample was drawn. It is well known that oxygenation can change very quickly. In the absence of continuous oxygenation monitoring, these changes may go undetected until it is too late.
Pulse oximeters measure blood oxygen saturation noninvasively and continuously.
What is SpO2?
A blood-oxygen saturation reading indicates the percentage of hemoglobin molecules in the arterial blood which are saturated with oxygen. The reading may be referred to as SaO2. Readings vary from 0 to 100%. Normal readings in a healthy adult, however, range from 94% to 100%.
The term SpO2 means the SaO2 measurement determined by pulse oximetry. As explained in the section "Considerations When Using Pulse Oximetry," under some circumstances pulse oximetry gives different readings, and the use of a different term indicates this.
How Does Pulse Oximetry Work?
Within the Sp02 sensor, light emitting diodes shine red and infrared light through the tissue. Most sensors work on extremities such as a finger, toe or ear. The blood, tissue and bone at the application site absorb much of the light. However, some light passes through the extremity. A light-sensitive detector opposite the light source receives it.
SpO2 Sensors
Most sensors work on extremities such as a finger, toe or ear. The sensor measures the amount of red and infrared light received by the detector and calcu- lates the amount absorbed. Much of it is absorbed by tissue, bone and venous blood, but these amounts do not change dramatically over short periods of time.
The amount of arterial blood does change over short periods of time due to pulsation (although there is some constant level of arterial blood). Because the arterial blood is usually the only light absorbing component which is changing over short periods of time, it can be isolated from the other compo- cents.

Oxygen Saturation As Presented in Wikipedia:
en.wikipedia.org/wiki/Oxygen_saturation_(medicine)
Oxygen saturation is a term referring to the fraction of oxygen-saturated hemoglobin relative to total hemoglobin (unsaturated + saturated) in the blood. The human body requires and regulates a very precise and specific balance of oxygen in the blood. Normal blood oxygen levels in humans are considered 95-100 percent. If the level is below 90 percent, it is considered low resulting in hypoxemia.[1] Blood oxygen levels below 80 percent may compromise organ function, such as the brain and heart, and should be promptly addressed. Continued low oxygen levels may lead to respiratory or cardiac arrest. Oxygen therapy may be used to assist in raising blood oxygen levels. Oxygenation occurs when oxygen molecules (O
2) enter the tissues of the body. For example, blood is oxygenated in the lungs, where oxygen molecules travel from the air and into the blood. Oxygenation is commonly used to refer to medical oxygen saturation.

Definition[edit]
In medicine, oxygen saturation (SO2), commonly referred to as "sats," measures the percentage of hemoglobin binding sites in the bloodstream occupied by oxygen.[2] At low partial pressures of oxygen, most hemoglobin is deoxygenated. At around 90% (the value varies according to the clinical context) oxygen saturation increases according to an oxygen-hemoglobin dissociation curve and approaches 100% at partial oxygen pressures of >10 kPa. A pulse oximeter relies on the light absorption characteristics of saturated hemoglobin to give an indication of oxygen saturation.
Physiology
The body maintains a stable level of oxygen saturation for the most part by chemical processes of aerobic metabolism associated with breathing. Using the respiratory system, red blood cells, specifically the hemoglobin, gather oxygen in the lungs and distribute it to the rest of the body. The needs of the body's blood oxygen may fluctuate such as during exercise when more oxygen is required [3] or when living at higher altitudes. A blood cell is said to be "saturated" when carrying a normal amount of oxygen.[4] Both too high and too low levels can have adverse effects on the body.
Measurement[edit]
An SaO2 (arterial oxygen saturation, as determined by an arterial blood gas test[5]) value below 90% causes hypoxemia (which can also be caused by anemia). Hypoxemia due to low SaO2 is indicated by cyanosis. Oxygen saturation can be measured in different tissues:
Venous oxygen saturation (SvO2) is measured to see how much oxygen the body consumes. Under clinical treatment, a SvO2 below 60% indicates that the body is in lack of oxygen, and ischemic diseases occur. This measurement is often used under treatment with a heart-lung machine (extracorporeal circulation), and can give the perfusionist an idea of how much flow the patient needs to stay healthy.
Tissue oxygen saturation (StO2) can be measured by near infrared spectroscopy. Although the measurements are still widely discussed, they give an idea of tissue oxygenation in various conditions.
Peripheral oxygen saturation (SpO2) is an estimation of the oxygen saturation level usually measured with a pulse oximeter device. It can be calculated with pulse oximetry according to the following formula:
SpO2 = HbO2/ (HbO2 + Hb)
Example: Pulse Oximeter
Pulse oximetry is a method used to estimate the percentage of oxygen bound to hemoglobin in the blood. This approximation to SaO2 is designated SpO2 (peripheral oxygen saturation). The pulse oximeter consists of a small device that clips to the body (typically a finger, earlobe or an infants foot) and transfers its readings to a reading meter by wire or wirelessly. The device uses light-emitting diodes in conjunction with a light-sensitive sensor to measure the absorption of red and infrared light in the extremity. The difference in absorption between oxygenated and deoxygenated hemoglobin makes the calculation possible.[5]
Medical significance
Effects of decreased oxygen saturation[6]
SaO2Effect
85% and aboveNo evidence of impairment
65% and lessImpaired mental function on average
55% and lessLoss of consciousness on average
Healthy individuals at sea level usually exhibit oxygen saturation values between 96% and 99%, and should be above 94%. At 1600 meters altitude (about one mile high) oxygen saturation should be above 92%.[7]
An SaO2 (arterial oxygen saturation) value below 90% causes hypoxia (which can also be caused by anemia). Hypoxia due to low SaO2 is indicated by cyanosis, but oxygen saturation does not directly reflect tissue oxygenation. The affinity of hemoglobin to oxygen may impair or enhance oxygen release at the tissue level. Oxygen is more readily released to the tissues (i.e., hemoglobin has a lower affinity for oxygen) when pH is decreased, body temperature is increased, arterial partial pressure of carbon dioxide (PaCO2) is increased, and 2,3-DPG levels (a byproduct of glucose metabolism also found in stored blood products) are increased. When the hemoglobin has greater affinity for oxygen, less is available to the tissues. Conditions such as increased pH, decreased temperature, decreased PaCO2, and decreased 2,3-DPG will increase oxygen binding to the hemoglobin and limit its release to the tissue.[8]
I've been hiking Wilcox Pass to look for Bighorn Sheep since 1988, but this was my first time in four years. I hauled out of bed - I mean sleeping bag - early and was on the trail in the dim dark of pre-dawn. No searching was required. I emerged from the trees onto an open ridge and spotted four rams almost immediately. They allowed a close approach and were very relaxed.
When rams reach maturity, their horns can curl tightly enough to block their peripheral vision, so they often "broom" the tips off by rubbing them against rocks.

Sandhamn (Swedish for "Sand Harbour") is a small settlement in the central-peripheral part of the Stockholm Archipelago in central-eastern Sweden, approximately 50 km (30 mi) east of Stockholm. Sandhamn is located on the island Sandön ("Sand Island"), which is, however, colloquially referred to as Sandhamn.
One of the most important natural ports in the archipelago with easy access to the Swedish capital, Sandhamn has been popular for pleasure boating since the late 19th century. It is known for its tavern, its clubhouse, and its harbour.
The island is approximately 9 km (5.6 mi) long and 6 km (3.7 mi) and consists mostly of sand and is dominated by beaches, dunes and especially pine forests.
Sandhamn receives an additional 100,000 visitors annually.
"Viveca Stens" popular novels come to life in "The Sandhamn Murders", a perfect mix of Nordic crime & the beautiful surroundings of the outer Stockholm archipelago.
Sandhamn (le nom veut dire port de sable) est une petite île de Suède située sur la mer Baltique. La population de ce petit port de pêcheurs n'excède pas les 110 habitants. Le tourisme y est développé grâce à des liaisons maritimes Stockholm-Sandhamn régulières en été.
Cette île est le lieu où se déroule l'action du roman La Reine de la Baltique de l'auteur Viveca Sten. Une adaptation de ce roman pour la télévision est diffusée en France sous le titre de "Meurtres à Sandhamn".
Peripheral roads. With the bus line 78 stops at the terminus Bisceglie in connection with the Underground line 1
As I walked along the country road in the darkness I could only hear my own footsteps and my breathing matching my feet for pace. But my eyes became drawn to a swirl of white in the distance. I couldn't quite catch the swirl's form as I drew nearer, right up until she hit my peripheral vision and swam in the air before me... a vision.

And still on Edinburgh's peripherals and to the north-west and the new Cammo terminus. In days now gone I viewed Edinburgh's Baillies and Councillors as strong custodians of the city's green belt and its difficult to think of a 'greener' area than the Cammo estates and its surrounds. However that mantra has slipped somewhat in recent years as more and more the city's green belt disappears.
A large number of houses have now been built here at Cammo, not far from Edinburgh airport and on the border of East Craigs another 'new' housing area. Lothian have seen fit to provide a service to the new area in the shape of extending service 41 which previously terminated to the north at Cramond. Older stock now seems the 'norm' on the 41 as seen here with fleet 372 at the Cammo terminus in a 'seaonal' downpour of rain which appears to have won a contest with the new drains! 372 will work back to Cramond and follow the old 41 route across the city to The Grange and King's Buildings.
This view is always and forever the real view of a Jack Rabbit; one quick glimpse as it heads for the underbrush. This is a different animal from the one on the berm. But just as unhappy to see me.
A few things I notice in this photo: the thin delicacy of the huge ear, the strength of the muscles supporting those ears and if you look closely on the right side of its head, you can see its eyeball even from this perspective. This rabbit has some amazing peripheral vision; it can see me even though I am directly behind it.
Good peripheral vision is definitely an asset when it comes to riding a motorcycle.

While patiently waiting for the hikers to clear out in this area of Wall Street in the Narrows of Zion NP, I noticed a certain glow on my right that turned-out to be the tree and the wall behind it being lit by the light bouncing on the wall on my left. I quickly changed my composition and was able to fire some shots before the light moved out of frame. Patience has it's rewards, always, it seems.
