Camera Exposure: Aperture, ISO & Shutter Speed

Camera Exposure: Aperture, ISO & Shutter Speed
A photograph's exposure determines how light or dark an image will appear when it's been captured by your camera. Believe it or not, this is determined by just three camera settings: aperture, ISO and shutter speed (the "exposure triangle"). Mastering their use is an essential part of developing an intuition for photography. Achieving the correct exposure is a lot like collecting rain in a bucket. In photography, the exposure settings of aperture, shutter speed and ISO speed are analogous to the width, time and quantity discussed above. Each setting controls exposure differently: Aperture: controls the area over which light can enter your cameraShutter speed: controls the duration of the exposureISO speed: controls the sensitivity of your camera's sensor to a given amount of light One can therefore use many combinations of the above three settings to achieve the same exposure. By the Numbers. How it Appears. Slow Shutter Speed Fast Shutter Speed By the Numbers. How it Appears. Related:  PHOTO TOOLS

Take a Photo a Day Understanding White Balance White balance (WB) is the process of removing unrealistic color casts, so that objects which appear white in person are rendered white in your photo. Proper camera white balance has to take into account the "color temperature" of a light source, which refers to the relative warmth or coolness of white light. Our eyes are very good at judging what is white under different light sources, but digital cameras often have great difficulty with auto white balance (AWB) — and can create unsightly blue, orange, or even green color casts. Color Cast Daylight White Balance Color temperature describes the spectrum of light which is radiated from a "blackbody" with that surface temperature. Relative intensity has been normalized for each temperature (in Kelvins). Note how 5000 K produces roughly neutral light, whereas 3000 K and 9000 K produce light spectrums which shift to contain more orange and blue wavelengths, respectively. The first three white balances allow for a range of color temperatures.

Guía Detallada: Cómo Hacer Fotografía De Humo ¿Siempre has querido hacer una fotografía como esta, pero pensabas que era extremadamente difícil? Pues lamento decirte que estabas en un error… En este tutorial te explico los pasos para que puedas hacer la prueba en tu casa y veas que no es tan complicado. Sólo hace falta un poco de paciencia, tiempo y algunos materiales. Humo, por Juan Miguel Rogado Materiales Trípode.Tela negra. Cómo preparar tu “mini estudio” casero Coloca la tela negra como fondo y frente a ella el trípode con tu cámara, a ser posible, con un objetivo macro. El flash tienes que colocarlo a un lado, formando 90º con la cámara, para que no ilumine el fondo, además, será mucho mejor, para evitar que refleje sobre la tela, colocar la cartulina negra entre la tela y el flash externo. Entre el fondo y la cámara, obvio, coloca tu fuente de humo. Por si no me he explicado bien, aquí tienes un esquema para que lo veas mejor: Posición de los materiales para una fotografía de humo óptima Aspectos técnicos Procesado de la imagen

JOOMEO PHOTO STORAGE Canon EF-S lens mount An example of a plastic EF-S lens mount. The Canon EF-S lens mount is a derivative of the EF lens mount created for a subset of Canon digital single-lens reflex cameras with APS-C sized image sensors. It was released in 2003. The "S" in EF-S comes from "Small image circle", meaning the lens is designed to provide a small (relative to a normal EF lens) image circle to match the sensor.[1] The smaller mirror used in APS-C cameras also allows optical elements to protrude further into the camera body, which enhances the possibilities for wide angle and very wide angle lenses, enabling them to be made smaller, lighter (containing less glass), faster (larger aperture) and less expensive. Although not all Canon EF-S lenses use this short back focus, they cannot be mounted on non APS-C cameras. Compatibility[edit] The cameras that can use the EF-S mount are: An EF-S compatible mount close-up, from the Canon 30D. List of EF-S lenses[edit] EF lens (left) and EF-S lens (right).

How to take outdoor portraits Taking photos outdoors is challenging. Besides dealing with people stealing your gear, insects attacking you, and property owners wanting money to let you shoot on their land, you have to worry about constantly changing sunlight. Learning how to react quickly and effectively to lighting changes is the key to producing good photos. We'll cover a few different lighting strategies, but please leave comments if you have your own techniques and experiences that you want to share. You are on your own with the insects. Lighting varies during the day Imagine that you rented a studio with nice lighting equipment, placed all the lights exactly where you wanted them, and then started taking pictures of a model. Well, that's basically what happens when you photograph outside. Remember, anyone can take one good photo given enough tries in front of a nice sunset. The sun is a light that you can't control The sun is just another light source. The exception to this chart is cloudy weather. Comments
