Golden Triangle Photography (basic photography)

Light is absolutely necessary to produce a photograph. To produce an image, we must be able to regulate the amount of light for the image that we can not over (extra light) or under (the lack of light).

In photography there are three basic components that are interconnected to one another. The three components are:

1. ASA / ISO (sensitivity to light media)

In photography we know the film (analog cameras) and sensor (digital camera), the medium used to capture light to produce an image. Film and media censorship is sensitive to light, sensitivity to light is categorized by units of ASA / ISO.

Figures for the ASA / ISO used were 25, 50, 100, 200, 400 and so that is a multiple of the previous figure. The greater the number of ASA / ISO the more sensitive to light.

Use of ASA / ISO in large numbers allows shooting in low light situations. Will continue the use of ASA / ISO in large numbers produce a rough image, there are spots - spots on the image or often called noise.

2. Shutter Speed (Speed)

Shutter speed is a mechanical device inside the camera to adjust the length of light into the camera in seconds.

Figures for the shutter speed that is B, 1, 2, 4, 8, etc. The maximum number depends on the ability of the camera.

The use of shutter speed in large numbers to take pictures of moving objects produce the effect of freeze or moving objects such as - if silent. While on a small number will produce longitudinal line effect.

3. Diaphragm

The diaphragm is a mechanical device inside the camera to set the number (more / less) of light entering the camera. This mechanism is located on the camera lens.

Numbers listed on the diaphragm 1.4, 1.8, 2.8, 4, 5.6 ff. The bigger the number the smaller the aperture amount of light entering the camera.

The diaphragm has the effect on the image, called depth of field (Dof) or the space sharply. If the numbers diaphragm mounted on a small number, the sharper will be increasingly narrow space. We can produce images focus on specific parts and other parts blur or out of focus. Usually these small numbers diaphragm use for taking pictures of models, produce effects on the model and blur the focus on the background. In contrast to the use of the diaphragm in large numbers, will produce a sharp room spacious. Its use is usually for purposes of landscape photos (turbulent), as usual want images that focus from the closest point to the farthest.
