Digital Photography

Exposure in Photography is determined by the Shutter Speed, the aperture of the lens, the sensitivity of the ISO and the lighting of the scene. In this post I'm going to talk about the Lighting of the Scene. Great cinematography is all about preparation, and few aspects of the craft require as much preparation as lighting. You can arrange the lights in such a way as to leave darkness between the area illuminated by the backlight and the area illuminated by the fill light, depending on how moody you want the shot to be. This tends to work very well, although even the moodiest films tend to avoid leaving dark shadows on the faces of female talent. The film still shown above is from “Schindler’s List” and is a good example of this technique. You should light your film or video shot by shot. This means that when you relocate the camera to shoot a different angle, the lights must be moved as well to ensure the subject is always lit correctly. This is partl

Exposure in Photography is determined by the Shutter Speed, the aperture of the lens, the sensitivity of the ISO and the lighting of the scene. In this post I'm going to talk about ISO. In very basic terms, ISO is the level of sensitivity of your camera to available light. The lower the ISO number, the less sensitive it is to the light, while a higher ISO number increases the sensitivity of your camera. The lower the number the lower the sensitivity of the film and the finer the grain in the shots you’re taking. The component within your camera that can change sensitivity is called “image sensor” or simply “sensor”. It is the most important (and most expensive) part of a camera. Traditionally in film ISO refers to the sensitivity of the film but with digital photography it refers to the sensitivity of the sensor.  Film Sensor Take a look at the image below a higher ISO gives a grainier image and a lower ISO gives clear image. Higher ISO settings a

Exposure in Photography is determined by the Shutter Speed, the aperture of the lens, the sensitivity of the ISO and the lighting of the scene. In this post I'm going to talk about Aperture. Simpy put Aperture is ‘the opening in the lens.’ When you press the shutter release button on the camera the the whole opens to the desired opening (also called f stops). The larger the hole the more light that gets in – the smaller the hole the less light. Keep in mind that a change in shutter speed from one stop to the next doubles or halves the amount of light that gets in also – this means if you increase one and decrease the other you let the same amount of light in – very handy to keep in mind). There are a number of results of changing the aperture of your shots that you’ll want to keep in mind as you consider your setting but the most noticeable one will be the depth of field that your shot will have. For example in the photo below the guitar is in focus and the backg

Exposure in Photography is determined by the Shutter Speed, the aperture of the lens, the sensitivity of the ISO and the lighting of the scene. In this post I'm going to talk about Shutter Speed. Shutter speed refers to how fast the shutter on the camera fires in order to capture the picture. The shutter is like a curtain in front of the sensor that opens when the user presses the button which allows light into the sensor. With a faster shutter speed you can freeze the pinwheel as if its not moving, with a slower shutter speed you can get a smooth effect on the pinwheel. Shutter speed is measured in fractions of a second. For example a shutter speed of 1/10 means a tenth of a second. Most modern camera's are able to take pictures up to 1/4000th of a second. Shutter speed is set differently on every camera but there is always an auto option for general photography. In order to customize the shutter speed you need to set the camera into manual mode. from there yo
