Balance is the distribution of the visual weight of objects, colors, texture, and space.
If the design was a scale, these elements should be balanced to make a design feel
stable. In symmetrical balance, the elements used on one side of the design are
similar to those on the other side; in asymmetrical balance, the sides are different
but still look balanced. In radial balance, the elements are arranged around a central
point and may be similar.

Barrel distortion describes a type of distortion wherein lines that are straight in real life appear to curve inwards (like the walls of a barrel). A good way to check for barrel distortion is to look for parallel lines in the area you are shooting and see if the lines appear parallel in your image.

# data[].attributes.body
Pincushion distortion is the exact opposite of barrel distortion – straight lines are curved outwards from the center. This type of distortion is commonly seen on telephoto lenses, and it occurs due to image magnification increasing towards the edges of the frame from the optical axis.

In 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. Wikipedia

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

Partial Metering is a camera-metering mode in which the metering is weighted at the center of the viewfinder (unlike center-weighted in which the camera averages the exposure based on the reading at the center). ... Partial metering will enable correct exposure of your subject, however the background will be over-exposed.

# 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.
