Negative space, in art, is the space around and between the subject of an image. Negative space may be most evident when the space around a subject, not the subject itself, forms an interesting or artistically relevant shape, and such space occasionally is used to artistic effect as the "real" subject of an image.

# data[].attributes.body
Positive space refers to the subject or areas of interest in an artwork, such as a person's face or figure in a portrait, the objects in a still life painting, or the trees in a landscape painting. Negative space is the background or the area that surrounds the subject of the work.

For digital photography, ISO refers to the sensitivity—the signal gain—of the camera's sensor. The ISO setting is one of three elements used to control exposure; the other two are f/stop and shutter speed. ... With film cameras, using a higher ISO film, such as ISO 400 to 1000, often resulted in noticeable grain.

# data[].attributes.body
Film speed is the measure of a photographic film's sensitivity to light, determined by sensitometry and measured on various numerical scales, the most recent being the ISO system. A closely related ISO system is used to describe the relationship between exposure and output image lightness in digital cameras.

# data[].attributes.body
An image sensor or imager is a sensor that detects and conveys information used to make an image. It does so by converting the variable attenuation of light waves into signals, small bursts of current that convey the information. The waves can be light or other electromagnetic radiation.

# data[].attributes.body
Film grain or granularity is the random optical texture of processed photographic film due to the presence of small particles of a metallic silver, or dye clouds, developed from silver halide that have received enough photons. ... It can be objectionably noticeable in an over-enlarged film photograph.

mage noise is random variation of brightness or color information in images, and is usually an aspect of electronic noise. It can be produced by the image sensor and circuitry of a scanner or digital camera. Image noise can also originate in film grain and in the unavoidable shot noise of an ideal photon detector.

In optics, an aperture is a hole or an opening through which light travels. More specifically, the aperture and focal length of an optical system determine the cone angle of a bundle of rays that come to a focus in the image plane. An optical system typically has many openings or structures that limit the ray bundles.

Here's how to take advantage of this mode: Set the shooting mode to Auto. ... For still subjects, most cameras lock focus when you depress the shutter button halfway.

# data[].attributes.body
As the name suggests, “Manual” mode stands for a full manual control of Aperture and Shutter Speed. In this mode, you can manually set both the aperture and the shutter speed to any value you want – the camera lets you fully take over the exposure controls.

# data[].attributes.body
Aperture priority, often abbreviated A or Av on a camera mode dial, is a setting on some cameras that allows the user to set a specific aperture value while the camera selects a shutter speed to match it that will result in proper exposure based on the lighting conditions as measured by the camera's light meter.

# data[].attributes.body
Shutter priority, also called time value, refers to a setting on some cameras that allows the user to choose a specific shutter speed while the camera adjusts the aperture to ensure correct exposure.

# data[].attributes.body
Program mode (the "P" on the mode dial of most DSLRs) means that the camera still sets the exposure for you. It chooses the correct aperture and shutter speed for the light available, so your shot is correctly exposed. Program mode also unlocks other functions that give you more creative control over your images.

# data[].attributes.body
n photography, shutter speed or exposure time is the length of time that the film or digital sensor inside the camera is exposed to light when taking a photograph. The amount of light that reaches the film or image sensor is proportional to the exposure time. 1⁄500 of a second will let half as much light in as 1⁄250.

With spot metering, the camera will measure only a very small area of the scene (1–5% of the viewfinder area). ... Spot metering allows the camera to measure the light reflected from the person's face and expose properly for that, instead of adjusting exposure for the much brighter light around the hairline.

# data[].attributes.body
Partial metering covers only the centre 6.2% of the frame in the viewfinder, thus providing precise metering only for the subject. When the background is brighter than the subject due to reasons like back lighting, this metering mode is particularly useful.

# data[].attributes.body
Center-weighted average metering works on the assumption that the most important part of the image is probably in the center. It measures the whole scene but places extra emphasis on the light values in the middle. Center-weighted averaging is a bit of a throwback.

# data[].attributes.body
Evaluative metering is the mostly used automatic metering mode in everyday photography and can be applied in most shooting scenarios. As its name suggests, it takes a series of readings in zones that cover the entire frame, and then calculates the overall average exposure value.
