Shutter speed
Shutter speed refers to the amount of time it takes to open and close the
shutter, and it is an important factor in the brightness of a photo, as it
controls the amount of light which passes through the aperture before
it reaches the image sensor. A fast shutter speed allows less time to let
light in and the photo becomes darker and more easily freezes subjects in
motion.
sRGB (Standard RGB)

Electrotechnical Commission). This is dened from color space for PC
monitors and is also used as the standard color space for Exif.
Vignetting

edges) compared to the center of the image. Vignetting can draw interest
to subjects positioned in the center of an image.
White Balance (Color balance)
An adjustment of the intensities of colors (typically the primary colors red,
green, and blue), in an image. The goal of adjusting the White Balance, or
color balance, is to correctly render the colors in an image.
