We could talk about many technical things like how to get the right exposure using which metering mode or how interacts the shutter speed with the aperture and ISO etc. Even if you know perfectly all of these things, you cannot do anything good without understanding the light. Sometimes it’s just good to go back to basics: Light.
It goes without saying that it can be expressed in every photography field: Landscape, Wedding, Portrait, Macro, Architecture etc.
Photographing literally means “engraving with light”. This is the element that can completely transform a photograph. This is what every photographer tries to control, to work with as a raw material, its intangibility and subtlety gives magic or tells a story. Without light: shadow, darkness. No light, no contrast, no color.
