Where begins Photo: basic settings

In the same way as buying a scalpel will not make you a competent surgeon, tricked out the purchase of the camera does not automatically increase the quality of your shots. If you want good pictures, you will have to study and learn many different things. Start with the basics is necessary.

Offering the user a lot more features, advanced technique requires replace the knowledge and skills to use these same features. Today, we will help beginners to understand the connection aperture, shutter speed and ISO sensitivity - the three key parameters in digital photography.

Diaphragm - the size of the lens aperture through which light passes at the time of shooting. designated f / xwhere x It indicates how open the aperture, with a smaller number means a larger aperture value. For the beginner it is sufficient to understand that the smaller x, The more clearly highlight the key object of the picture, and other background will be blurred. This is useful when you want to focus on a single element of the picture.

The higher the value xThe more will be a clear background.

excerpt - the amount of time during which the light will fall on the image sensor of the camera when a picture is taken. Fast shutter speed is indicated by fractions of a second, eg 1/500 - one five hundredth of a second. Long exposure (from seconds or more) - as a number indicating the number of seconds, and quotation marks, e.g., 2 "or 4". The longer the shutter speed, the more time will be fixed by your subject, and accordingly, its movement and the movement of the lens itself, which manifest themselves blur.

Fast shutter speed, on the contrary, allows both to stop the clock and get a clear picture of even fast-moving subject.

photosensitivity - the sensitivity of the camera array to light, measured in units of ISO. The higher the ISO value set in the camera settings, the higher the sensitivity. Too low ISO takes pictures dark and washed-out and unnecessarily high sensitivity can cause noise in the picture.

Ability to define the balance between the three basic parameters for each situation you can take photos with the perfect brightness and color reproduction. The amount and intensity of light in combination with the time during which the light is to act on the image sensor, how to get a permit, and hopeless ruin magnificent frame.

How to understand and organize in my mind the relation of these parameters? Try to take advice from PictureCorrect and to control the shooting parameters of your usual morning coffee with milk.

Light - this milk in your coffee. Aperture - the size of the hole is in the package with milk. Shutter speed - the time during which you add milk in the coffee. Light sensitivity - is a fortress of coffee.

The larger hole in the package (aperture), the more milk passes therethrough. The longer you hold the bag on a cup (excerpt), the more milk gets out of the bag in the coffee. If you can not get good control of the amount of added milk, then you'll want to initially make coffee stronger to its final fortress was less sensitive (lower sensitivity) to the number of milk in it.

Start experimenting with these settings should in good light. Select an object to shoot, and then change the values ​​and evaluate the results.

When it's a general understanding of the relationship of shooting options with the result, begin to change the illumination of the object. So you'll see the connection parameters and results under different conditions of shooting.

The next step will be shooting a moving subject. Here you will fully uncover for themselves the effect of shutter speed and ISO sensitivity on the resulting photographs. Start filming moving objects with low sensitivity and long exposure.

Most cameras shooting control data parameters automatically and relieve the photographer from having to think about them, but if you want to go beyond Standard Amateur shooting, the manual adjustment of aperture, shutter speed and ISO sensitivity will open in front of you virtually unlimited golf experiments. Well, not to be distracted by too much in the study of, a beginner photographer recommended to enable auto focus on the experiments.
