Parallax

An effect in which the image viewed through the viewfinder of a camera differs from the image seen through the lens of the camera, which causes portions of the scene to be absent from the photograph taken by the camera. It is found in all types of cameras, including Leica rangefinders and twin-lens reflex cameras, as well as other types of cameras with separate viewfinders and lenses.

Passive autofocus

An autofocus system that does not actively measure the subject distance but rather adjusts the focus of the lens based on an analysis of the image itself. The majority of digital cameras have a focusing method known as passive autofocus, which is sometimes referred to as phase-detection or contrast-detection autofocus.

Pancake lens


An very thin lens that is typically a prime lens but can occasionally be a zoom lens. These lenses are designed to be more narrow than they are broad and are intended to be portable, lightweight, and compact.

Pack shot


The term "packaging shot" has been shortened to just "shot," and refers to a photograph of a product that has its labeling prominently displayed. These photographs are typically taken for advertising or other commercial purposes. There is a wide range of possible studio setups for pack shots, from the most basic to the most complex.

Over-exposure

Exposing a photograph for a period of time that is excessively long considering the topic and the lighting circumstances. As a consequence of this, the features in the highlight areas get distorted or "blown out." When trying to achieve a specific effect, certain photographers favor using an overexposed shot. They may also utilize an overexposure technique to compensate for instances in which the camera's light meter provides an inaccurate reading, such as when they are photographing snow scapes.

North light


The indirect and reflected light that enters a room through windows that face north and are not, as a result, directly illuminated by the sun. Because of its gentle and enveloping nature, it is frequently used in portrait photography.

Noise

An unwanted interruption in an electrical transmission that appears as a grain-like pattern in the darker regions of a digital image. When using a higher ISO level, digital photographs will exhibit an increase in noise.

Negative

An image that has been created on a sheet or strip of film that is made of clear plastic. On black-and-white negative film, tones are recorded in the opposite order, whereas on color negative film, colors are recorded in the order of their complimentary colors. When printed on photographic paper, negatives are altered such that the resulting images are positive. In the year 1835, William Henry Fox Talbot used his calotype process to create the very first negative that was ever recorded on paper.

Naturalistic photography


A style that was developed in the 1880s by the English photographer Peter Henry Emerson (1856-1936). He believed that images have to have a straightforward and uncomplicated appearance and reflect nature. He further stated that they should not be staged or retouched before being produced, and that they should be generated from a single negative (as opposed to the use of numerous negatives in combination printing).

Motion blur


A streaking effect that results from the subject or camera moving during the exposure time, causing the image to be blurry. Examples of this technique include taking a long exposure photograph of a moving object passing through a stationary nighttime street scene or panning the camera while focusing on a moving subject in order to produce a background that is blurred.

Monopod

A one-legged camera support. Even this this does not offer the camera with absolute stability, it does make it feasible to use slower shutter speeds than would normally be possible when using a handheld camera. Because of its flexibility, it is commonly used by photographers who cover sports.

Monochrome

In photography, the phrase "monochrome" most commonly refers to black-and-white photos. However, the term "monochrome" can also be used to describe images that were created using only one color or tones of the same color. The "monochrome mode" found on digital cameras gives users the ability to record directly in black and white, eliminating the need to convert color photographs to monochrome later on in the post-capture process.

Moiré pattern

Moiré is a photographic effect that happens when a detailed or repeating pattern in the subject is overlaid with the pattern of pixels on a digital sensor. This can happen when taking close-up or long-exposure photos. The combination of the two patterns results in the formation of a third, distinct, and frequently undulating moiré pattern. The effect is mitigated thanks to the optical low pass filter inside the camera.

Mirrorless camera


A design for a camera with interchangeable lenses that eliminates the mirror used in digital SLRs and older film SLRs and instead relies on the main sensor to display the image in the viewfinder of the camera.

Midtones

All of the parts of an image that are neither its highlights nor its shadows. These are bright areas of the picture that, if the picture were to be converted to black and white, would appear to be a shade of gray rather than either black or white. These areas coincide with the primary and secondary centers of the histogram graph in a histogram.

Metered manual


A mode of exposure in which the shutter speed and aperture are selected manually by the user, despite the fact that the camera's internal light-metering system provides information as to whether or not these settings are appropriate.

Medium-format camera

Any camera that uses film that is larger than 35mm but is not as large as 4x5 (also known as large format film). In the field of digital photography, the term "full frame" refers to cameras that use image sensors that are larger than 36 mm by 24 mm.
