Lens and mounting of a large-format camera Photography is the science, art and practice of creating durable images by recording light or other electromagnetic radiation, either electronically by means of an image sensor, or chemically by means of a light-sensitive material such as photographic film.[1] Photography is employed in many fields of science, manufacturing (e.g. photolithography) and business, as well as its more direct uses for art, recreational purposes, and mass communication.

Etymology[edit] The word "photography" was created from the Greek roots φωτός (phōtos), genitive of φῶς (phōs), "light"[2] and γραφή (graphé) "representation by means of lines" or "drawing",[3] together meaning "drawing with light". Several people may have coined the same new term from these roots independently. History[edit] Precursor technologies[edit] A camera obscura used for drawing images Photography is the result of combining several technical discoveries. Comment bien utiliser votre testeur de profondeur de champ. Au cours de mes stages, je me suis aperçu que la plupart des possesseurs d’appareils Reflex ne savent pas utiliser correctement leur testeur de profondeur de champ. Pire, ils ne savent en généralement pas à quoi cet accessoire peut bien servir !

Sur un appareil reflex, la visée se fait au travers de l’objectif. Pour conserver un viseur bien clair, les ingénieurs ont mis au point ce que l’on appelle la présélection du diaphragme. Comme son nom l’indique « pré sélection », ce dispositif permet de choisir le diaphragme qui sera utilisé au moment du déclenchement, mais seulement au moment du déclenchement.

En effet, si vous choisissez une ouverture assez réduite comme f/16 ou f/22, le trou laissant passer la lumière dans l’objectif étant très réduit, votre visée serait très sombre. En fait, sur les appareils modernes, lorsqu’on choisit une ouverture de diaphragme, le diaphragme reste ouvert à sa plus grande ouverture. Premier exercice Deuxième exercice Troisième exercice. Technique photo. Comprendre la profondeur de champ. Un réglage judicieux de la profondeur de champ permet de personnaliser ses photos et de mettre en valeur son sujet. La Profondeur de Champ (P de C ou PdC) se détermine par le choix du diaphragme. Avec un appareil photo sans système de bascule du plan-film ou du plan de l’objectif, les différents plans de netteté sont parallèles entre eux et parallèles au plan du film ou au plan du capteur numérique.

La chambre grand format, appelée aussi banc optique, permet par ses grandes possibilités de bascule et décentrement une plus grande maîtrise de la profondeur de champ. Ce qui en fait un appareil toujours apprécié, malgré l’avènement du numérique. Il est à noter qu’il est possible d’adapter un dos numérique sur une chambre grand format. La netteté faite sur un endroit précis du sujet, ne s’arrête pas brutalement mais, s’étend progressivement sur une zone plus ou moins étendue, en avant et en arrière du sujet, par rapport au point de prise de vue.

The Remove app is designed to remove bystanders from photos taken by mobile devices Image Gallery (3 images) It's kind of a funny thing, when you think about it ... even though it's normal to see other people milling about in public places, when we take photos of those places, we often don't want any of those people in our pictures.

Ordinarily, this means standing around and waiting, then blasting off a shot in the split second when no one is within your frame - except perhaps the person you're taking a photo of. Swedish photography company Scalado, however, has now developed an alternative for use with mobile devices. It's called Remove, and appropriately enough, it removes those pesky "other people" from your photographs. Remove works by initially taking a burst of shots in succession.

The app is presently still in the prototype stage, but a full version should be ready for a demonstration later this month, at the 2012 Mobile World Conference in Barcelona.

Fantastic photomontage and its possible influences, 1857 - 2007 : a timeline ... interior frame. Edgar Allen Poe 1850/6: The Works of Poe The Works of the Late Edgar Allan Poe were published in the U.S. (1850 & 1856), although sadly edited by someone who sometimes freely rewrote and recombined the stories. Poe (1809-1849) had been known in his own lifetime — but only as a critic, not as a writer of fiction. Poe's works, along with de Sade and the recovery of European folk/fairy tales, became the seeds of a sophisticated gothic imagination (there had been an unsophisticated pre-1848 literature of 'Penny Dreadfuls' and a brief British craze for horror stage shows) — which can be seen running through Stevenson's Hyde (1886), the 'L'Esprit Decadent' novels of the 1880s, James' The Turn of the Screw (1898), Ernst's collage novels, Lovecraft, Mervyn Peake, Borges, Ray Bradbury, Angela Carter, to Jan Svankmajer and beyond. ← return to index Oscar Gustave Rejlander 1857: "The Two Ways of Life".

Tree planters are often placed on the streets with good intentions of adding a necessary boost of green space, yet they can often become neglected within large sprawling cities where no one takes direct responsibility. Martindale hopes that his Outside the Planter projects encourage people to have more direct participation and interest in their shared public spaces. As he states: “We all have stakes in our shared environments, and this public project directly engages with Toronto’s urban fabric. One of the primary intents of the Outside the Planter Boxes project is to encourage more direct participation and interest in our shared public spaces - to demonstrate that the public can play a more consciously active role in how our city is shaped.”

The project was supported by a Toronto FEAST Grant and Sean asked participants not to cause any major permanent damage as the installations were not authorized by the City of Toronto. . + Outside the Planter + Sean Martindale Via INSPIX.
