Aperture and shutter speed are the two most important tools of a photographer to influence the look of the image. Apart from controlling the amount of light reaching the image sensor, the aperture affects the depth of field and the shutter speed influences the motion of the subject.
The white balance ensures an assignment of color temperature to the given light source. Besides the automatic function, the white balance can also be set manually.
The quality and balance of the imaging performance depends on several factors, like optical aberrations or the sensor format.
Chromatic aberration is a common lens aberration that appears as „color fringes“ or “purple fringing” along the borders of very dark or very bright parts of an image. But how does it occur and can it be avoided?
Even when holding the camera very steady or using a tripod, images can still suffer from camera shake that is induced by the movement of the mirror, the shutter or the movement that is caused by pressing the shutter release button.
In this article we describe the differences between contrast, phase detection and hybrid autofocus.
The exposure value represents a combination of aperture and shutter speed in relation to the sensitivity. Knowing those parameters enables the photographer to influence the look of the image, while maintaining a correct exposure.
