Symmetry (also known as formal balance) is achieved when both sides of the image hold equal weight. Photographers have creative license to take this 'symmetry' as literally or as figuratively as they please, as you can see by the two examples below.

# data[].attributes.body
When a photo is asymmetrical, it has unequal visual weight on either side. But those visual elements balance out each other. This means that an asymmetrical photo still follows the rules of composition.

ISO is your camera's sensitivity to light as it pertains to either film or a digital sensor. A lower ISO value means less sensitivity to light, while a higher ISO means more sensitivity.

# data[].attributes.body
The ASA (American Standards Association) scale is an arbitrary rating of film speed; that is, the sensitivity of the film to light. If everything else is kept constant, the required exposure time is inversely proportional to the ASA rating.

# data[].attributes.body
The image sensor of the camera is responsible for converting the light and color spectrum into electrical signals for the camera to convert into zeroes and ones. All commercially available digital cameras (still, movie, or security) use one of two possible technologies for the camera's image sensor: CCD or CMOS.

# 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. While film grain is a function of such particles it is not the same thing as such.

The “f” in f-stop stands for the focal length of the lens. While focal length itself refers to the field of view of a lens, f-stop is about how much light you allow to hit the sensor via the aperture opening.

# data[].attributes.body
The focal length of a lens is determined when the lens is focused at infinity. Lens focal length tells us the angle of view—how much of the scene will be captured—and the magnification—how large individual elements will be. The longer the focal length, the narrower the angle of view and the higher the magnification.

# data[].attributes.body
In simplest terms, depth of field is how much of your image is in focus. In more technical terms, depth of field is the distance in an image where objects appear “acceptably in focus” or have a level of “acceptable sharpness.”

# data[].attributes.body
bokeh is the aesthetic quality of the blur produced in out-of-focus parts of an image. Bokeh has also been defined as "the way the lens renders out-of-focus points of light". Differences in lens aberrations and aperture shape cause very different bokeh effects.

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.

# data[].attributes.body
The centre-weighted mode is a halfway between matrix and partial metering. It measures the exposure of a pretty big metering spot in the viewfinder of the camera. Most people take photographs in which the subject is in the metering centre of the image.

# data[].attributes.body
Evaluative metering is the default metering mode on most cameras. It ensures that the camera will automatically adjust to the right exposure setting even when the ambient lighting shows greater contrast.

Autofocus (AF) points are what you use to determine where the camera will be focusing the image. When you look through your viewfinder, these are the rectangles or circles that you see.

# data[].attributes.body
when you bracket your shots you take exactly the same picture of your subject at several different exposures. This technique gives you a range of options to choose from when you're editing. As a result, it's much less likely that you'll end up with a badly underexposed or overexposed photo.

# data[].attributes.body
The exposure meter indicates the level of light reaching the sensor. Too much light results in over exposure which gives you a photo that is too light and lacking detail. Too little light results in under exposure which gives you a photo that is too dark and again, lacking detail.
