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.

Breathtaking Long Exposure Photography and How to Capture It As you know, our first free e-Book was launched and so we were all, including me, busy making Photoshop resources. Thanks to you, the e-Book has met with a landmark success. Now I am free to focus on the other subjects as well. For today, I chose a form of trick photography. So after many weeks, here’s a super tutorial for learning Long Exposure Photography. As the name suggests, long exposure photo is when the camera’s image sensor was exposed to light for a longer period of time than usual.

Understanding Digital Camera Histograms: Tones and Contrast Understanding image histograms is probably the single most important concept to become familiar with when working with pictures from a digital camera. A histogram can tell you whether or not your image has been properly exposed, whether the lighting is harsh or flat, and what adjustments will work best. It will not only improve your skills on the computer, but as a photographer as well. Each pixel in an image has a color which has been produced by some combination of the primary colors red, green, and blue (RGB). The region where most of the brightness values are present is called the "tonal range." The above image is an example which contains a very broad tonal range, with markers to illustrate where regions in the scene map to brightness levels on the histogram. Lighting is often not as extreme as the last example. Before the photo has been taken, it is useful to assess whether or not your subject matter qualifies as high or low key.

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 Focusing Basics | Aperture and Depth of Field Depth of Field Depth of Field (DOF) is the front-to-back zone of a photograph in which the image is razor sharp. As soon as an object (person, thing) falls out of this range, it begins to lose focus at an accelerating degree the farther out of the zone it falls; e.g. closer to the lens or deeper into the background. With any DOF zone, there is a Point of Optimum focus in which the object is most sharp. There are two ways to describe the qualities of depth of field - shallow DOF or deep DOF. Shallow is when the included focus range is very narrow, a few inches to several feet. Aperture The aperture is the opening at the rear of the lens that determines how much light travels through the lens and falls on the image sensor. Small vs Large Aperture Manipulating the aperture is the easiest and most often utilized means to adjust Depth of Field. Aperture Range Distance from the Lens Conclusion You might also like:

Understanding Camera Lenses Understanding camera lenses can help add more creative control to digital photography. Choosing the right lens for the task can become a complex trade-off between cost, size, weight, lens speed and image quality. This tutorial aims to improve understanding by providing an introductory overview of concepts relating to image quality, focal length, perspective, prime vs. zoom lenses and aperture or f-number. All but the simplest cameras contain lenses which are actually comprised of several "lens elements." Optical aberrations occur when points in the image do not translate back onto single points after passing through the lens — causing image blurring, reduced contrast or misalignment of colors (chromatic aberration). Original Image Any of the above problems is present to some degree with any lens.
