The ideal proportion according to the ancient Greeks. It is visualized as the division of a line into two unequal segments in such a way that the ratio of the smaller segment to the larger segment is equal to the ratio of the larger to the whole. It is usually defined as 21,34, that is, 21/34 and 34/(21+34) both equal approximately 0.618. A rectangle whose sides are of this proportion is called a golden rectangle . Golden rectangles can be found in the proportions of the Parthenon and many medieval manuscripts.typographiaglossary
The time an hour or less before the sun goes down and around fifteen minutes after the sun has set. Sunlight is usually warmer and more complimentary to skin tones at this time, and the angle of the light can provide depth to portraits and landscape photography. This quality of light is also sometimes referred to as Photographer s light.
Also referred to as the Golden section and the Gold mean, the Golden mean is an ancient fine arts formula that mathematically defines a rectangle of specific proportions. This rectangle, called the Golden rectangle, is believed to frame objects in pleasing proportions. (See Rule of Thirds for more information.)
Also known as the Golden Ratio, Golden Mean, Golden Section or Divine Proportion. A rectangle of specific mathematical proportions that are closely approximated in the shape of a 35 mm film’s frame or the viewframe of a digital camera.
An image ratio (width vs the height) that makes the most pleasing, balanced impression on the viewer. Panoramics are long and skinny; square negatives often make it hard for the viewer to recognize the central focus of a composition. A 35mm format is pretty close to a golden retangle.
also called “magic hour” is the hour right before sunset or right after sunrise. The sun is low on the horizon and it is an optimal time for photography.
