What Does Open up Mean When Talking About Taking Photographs?
When taking photographs to ‘open up’ or ‘opening up’ refers to the practice of allowing more light to be recorded by a photographic medium for example a camera film or sensor. Opening up can be done in one of two ways; By selecting a larger aperture setting on a lens, or setting a longer exposure time on a camera. Both methods allow more light to be captured by the film or image sensor but have different creative effects.
