Technical quality in photography directly depends on the correct exposure. One of the most important elements that affect the accuracy of exposure is the ISO sensitivity. Film sensitivity, as well as sensitivity of a CCD sensor will be described in this research. The high light sensitivity (ISO setting) is used in low light conditions and to capture moving subjects. The sensitivity of the film is determined by the characteristics of the photo material, while the higher sensitivity of the sensor is achieved by boosting the signal on the sensor depending on the set ISO values. It is known that an increase in sensitivity results in lower quality images because of grain / noise that appear on the photo, and is always recommended to use the lowest possible ISO value depending on lighting conditions. That is why the aim of this study is to examine whether the granularity that occurs at a higher sensitivity in the analog photography is more acceptable than the appearance of noise in digital photography. The principle of analogue cameras and film types that are going to be used in the work, as well as the principle of a digital camera and sensor types that are found in such cameras will be described in this work. Digital camera with a CCD sensor will be used in this research, so the emphasis will be on this type of camera. The ways of removing the negative phenomena that occur at a higher sensitivity are going to be explained, but examples where such phenomena can contribute to the artistic atmosphere will also be shown.
