THE IMPORTANCE OF LIGHT IN PHOTOGRAPHY Proper lighting is crucial in photography because it underlines the real colours, dimensions, and features of the subject, bringing out a three-dimensional image. Sources of light The sources of light may be natural or artificial and can come from different angles: front lighting shows details and removes shadows; side lighting creates shadows and depth; What equipment is necessary to guarantee a stable, long exposure? A strobe is a device that uses a flashtube for high-speed illumination.

Natural and artificial lighting Natural light depends on the position of the sun. At midday, sunlight falls vertically and produces harsh shadows and plenty of contrast, making images often overexposed and blown out. In the morning and at the end of the day, the sun is closer to the horizon, so photos taken at sunset or sunrise have softer shadows. Light is not very intense, therefore sometimes a long exposure is necessary to capture it. Artificial lighting is produced with special devices, such as a studio strobe , LED light, a camera s flash, a streetlight, or a lamp.

The light is soft and diffused and has a characteristic golden glow; the blue hour occurs just after sunset and lasts for maximum 60 minutes. The sun is not in the sky anymore, so nothing casts a shadow. The images are soft and characterised by cool, blue tones. The same logic applies to sunrise, but it works in reverse: the magic hours start with the blue hour and gradually move into the golden hour. Artificial lighting
