Magnification ratio
The magnification ratio, or reproduction ratio as it’s also known, is a crucial feature.
Magnification ratio
Ratio that express greatest possible on film magnifying power of the lens. Used commonly on the macro setting of the zoom lenses, macro lens or with bellows.
Magnification ratio. A relationship that represents the amount of enlargement provided by the macro setting of the zoom lens, macro lens, or with other close-up devices.
Magnification ratios, the same as reproduction ratios, are the ratio between the size of your subject and the size of the image at the sensor or film. Of course when displayed or printed there is usually even more magnification.
Magnification ratio
Commonly referred to compact size sensors in modern DSLR cameras. Also know as crop factor.
Magnification ratio see Magnification.
Main light see Key light.
Mask is an opaque material used to cover the edges of the printing paper, and thus produce borders when the paper is exposed to light.
Special form of flashtube which is fired by mechanical (not electrical) means. Can be used only on cameras fitted with the appropriate socket.
Magnification ratio ...
Another way of achieving magnification ratios of greater than 1:1 is with a bellows assembly. Bellows is an accordion type extendable assembly that has a camera body mount board on one end and a lens mount board on the other.
Magnification ratio is calculated by dividing the focal length of the normally mounted lens by the focal length of the reversed lens (i.e., when a 18 mm lens is reverse mounted on a 300 mm lens a 16:1 magnification ratio is achieved).
Many are marked with the magnification ratio for which intended. These rarely have iris diaphragms, but this is not always a handicap. The good news is that they are usually very cheap.
Most macro photographic lenses have magnification ratios of 1:1 or 1:5. In 1:1 magnification ratio, the size of the subject in the image would be almost the same as in real life. Taking macro pictures can be done in a compact camera or in a DSLR.
Attached to the front of a lens its magnification ratio ability is increased by shortening the focusing distance. 0, 1, 2, 3T, 4T for 52mm diameter lenses; and 5T & 6T for 62mm, are the Nikon close-up lenses available.
Technically, a macro shot is one where the image is life-size or larger with a magnification ration of 1:1 or greater, but in general terms 'macro' is used to describe any close-up photography
Macro mode ...
I do not know what magnification ratio is this. Distance between front of camera lens to the ruler is some 1 centimeter I guess.
Close-up photography would start at magnification ratios of 1:10 and continuing down to 1:4. What this means is that the actual subject size in a 1:10 is 10 times larger than the capture image size on the sensor.
