Canon Explains Exposure

Canon Explains Exposure
A Little About Exposure: Exposure is the amount of light a digital camera's sensor captures when a photo is taken. Too much light results in a washed out photo (overexposed). Too little light and the photo will be too dark (underexposed). A camera's Aperture, Shutter Speed and ISO settings directly affect exposure, but more importantly, they allow you to control how each photo will look. Aperture - Control the amount of blur or sharpness around your subject. What it is and what it does: The aperture setting controls the size of the lens opening that allows light into your camera.You can blur the foreground and background that bracket your subject (known as shallow depth of field) by opening up the aperture with a low f-stop number; alternatively, you can keep your photo sharp from the foreground through to the background (known as wide depth of field) by closing the aperture down with a high f-stop number. Foreground and background blur make the subject stand out. Back To Top Related:  simulatoriculture artistiqueEducate Inspire Change

Fare pratica con i Simulatori Virtuali - Fotocamere Digitali Reflex Prove Confronto - Fotografia Digitale Test Fotografare senza fotocamera con i simulatori online Prendere dimestichezza con i fondamenti dell’esposizione fotografica e quindi tempi di posa, apertura di diaframma e sensibilità della pellicola-sensore è il primo passo da compiere per impratichirsi nell’utilizzo di una qualunque fotocamera digitale reflex. Nelle lezioni di fotografia e nella sezione dedicata alle numerose guide e tutorial presenti in rete c’è molto materiale sull’argomento ma quello che vogliamo presentare ora rappresenta un approccio nuovo e più immediato alla questione. Parliamo dei Simulatori di macchine fotografiche presenti online e pronti per un’utilizzo immediato da parte sia degli aspiranti utilizzatori di reflex che vogliano rendersi conto di ‘come funziona’ la regolazione dell’esposizione prima dell’acquisto di una fotocamera digitale sia per coloro che l’hanno appena acquistata ma hanno ancora qualche incertezza sul suo funzionamento. Vediamo quali sono i più conosciuti… E voi ne conoscete altri?

Fiac : l’infinie querelle de l'art contemporain • Brèves, FIAC, Art, Art contemporain, Jean Baudrillard, Baudrillard, Nathalie Heinich, Paradigme, Révolution La 43e édition de la Foire internationale d'art contemporain (Fiac) s'est ouverte ce jeudi 20 octobre sous la nef du Grand Palais et dans les galeries du Petit Palais, à Paris. 186 galeristes internationaux exposent les œuvres d'artistes actuels, attirant des collectionneurs de tous pays. S’il sert la spéculation, suscitant des estimations astronomiques et représentant avant tout un investissement[1], l’art nous aide-t-il encore à vivre? Délivre-t-il encore une forme de vérité sur le monde ? Depuis Marcel Duchamp, l’œuvre est sujette à réflexion plus qu’à contemplation. « La majeure partie de l'art contemporain s'emploie exactement à cela : à s'approprier la banalité, le déchet, la médiocrité comme valeur et comme idéologie. « Un art du faire-raconter » Nathalie Heinich se tient à distance des anathèmes. Les organisateurs de la Fiac l’ont bien compris.

How To Make a Cool Cinemagraph Image in Photoshop No doubt you’ll have heard of the term Cinemagraph since it exploded onto the Internets. Originally coined by Photographers Kevin Burg and Jamie Beck, a cinemagraph is a clever revival of the classic animated GIF. It combines features of video and photography to create a the illusion of a still image but with cool motion effects. Let’s take a look at how to create your own animated GIF cinemagraph by playing around with Photoshop’s animation tools. Some of the best cinemagraph examples can be found on the creators’ own website. As the popularity of the cinemagraph grew we began to see mobile apps such as Cinemagram emerge, which allows the easy creation of amateur cinemagraphs using the device’s built in camera. Cinemagraphs require some kind of motion, so while the final image looks much more similar to a photograph than a video, we need to begin with actual video footage. Use a tripod. Alternatively you could always play around with existing stock video footage. Download this file

Open Xerox: imaging-demos Service Home Page Xerox has extensive expertise in computer vision and imaging and this site presents some of our technologies through a range of easy to use demos. In many cases we use a combination of methods to solve real-world digital information management problems ranging from stock photography, digital asset management and personalised imaging through to cross-media search and smarter document technologies. We include here some mature technologies, and also some experimental demos which are in beta (or even alpha!) New ideas and demos will come and go on the page, as we try out new things and get user feedback. Similar Image Search For many applications, you need to search for similar images based on an image query -- rather than a keyword search on the web which returns images from related web pages that contain those keywords. This demo also allows you to retrieve images based on the output of our image classifier, which you can try out in more detail in the demo below! Image Categorizer

BetterPhoto Instructor Insights: Photography Panning for Sports and Action By Doug Steakley photo copyright by Doug Steakley Panning is the technique of following and photographing a moving subject with a shutter speed that is slow enough to cause the background to blur but fast enough to capture detail in the subject. Panning is a powerful technique for sports such as race cars, motorcycles, running or bicycling and it works equally well with wildlife. Panning can be used to photograph a bird in flight or a cheetah chasing a gazelle, and is an excellent technique for capturing a feeling of motion and action. While the technique appears to be easy it requires an understanding of the camera settings and practice. Panning is not the same as using a fast shutter speed to capture of freeze action such as a bird in flight because this requires a fast shutter speed and often a higher ISO.

The original DSLR camera simulator | CameraSim Lighting Lighting is the single biggest determinant of how your camera needs to be set. With only a few exceptions, you can never have too much light. Use this slider to experiment with different indoor and outdoor lighting conditions. Distance Use this slider to simulate how close or far you are in relation to the subject. Focal length Moving this slider is the same as zooming in and out with your lens. Mode The exposure modes of an SLR let you control one setting while the camera automatically adjusts the others. ISO refers to how sensitive the “film” will be to the incoming light when the picture is snapped. Aperture Aperture, or f-stop, refers to how big the hole will be for the light to pass through when the shutter is open and the picture is snapped. Shutter speed Shutter speed is how long the shutter needs to be open, allowing light into the camera, to properly expose the image. Happy simulating!

Guernica, de Picasso : un "rapt des Ménines" de Vélasquez. Vraiment ? Il y a 80 ans, Picasso commençait à peindre sa toile la plus célèbre, Guernica. En 1993, Juan Marin, docteur en art, déroulait une théorie étonnante en se livrant à une étude comparative de cette toile avec "Les Ménines" de Vélasquez, père spirituel de Picasso. Élucubrations œdipiennes ?... 1er mai 1937, il y a 80 ans : après le bombardement de la ville basque espagnole de Guernica par l'Allemagne nazie le 26 avril, Pablo Picasso a la rage au cœur. D'une archive de France Culture d'août 1993, intitulée "De Guernica à Guernica, histoire du tableau" et signée Elyane Milhau et Robert Grelier, une thèse étrange émergeait à propos de l'oeuvre : Juan Marin, Docteur en art et archéologie et auteur de Guernica, ou le rapt des Ménines (Lagune, 1994), s'était livré à une étude comparative de la toile et des fameuses Ménines, de Picasso.
