Exposure Value-denotes all combinations of a camera's shutter speed and relative aperture that yield the same exposure for a given scene luminance Golden Triangle-is an extrapolation on the golden ratio. If you use the same ratio to extrapolate a diagonal line, and then draw a perpendicular line to the corner, you’ve created a set of triangles that can guide your composition.
Bracketing- is the general technique of taking several shots of the same subject using different camera settings. Bracketing is useful and often recommended in situations that make it difficult to obtain a satisfactory image with a single shot. Histogram-a diagram consisting of rectangles whose area is proportional to the frequency of a variable and whose width is equal to the class interval. It graphs the tones in your image from black (on the left) to white (on the right). The higher the graph at any given point the more pixels of that tone that are present in an image
