Exposure In photography, exposure is the amount of light per unit area (the image plane luminance times the exposure time) reaching a photographic film, as determined by shutter speed, lens aperture and scene luminance. In digital photography "film" is substituted with "sensor".

There are three factors which influence the exposure of your image: -Shutter Speed -Aperture -ISO

Refers to how long the shutter is open, exposing the image sensor to light. (how long the camera sees the picture) Shutter speed, also known as exposure time, Measured in Seconds, from 30 down to 1/8000

Fast Shutter Speeds (600 and up) are used to stop motion and will freeze the subject.

Very Slow Shutter Speeds (5 sec. or slower) can be used in very low light situations to obtain correct exposure, or achieve dramatic effects.

An aperture is defined as a hole or opening through which light is admitted. Inside the camera lens is a system of blades which open and close to increase or decrease the opening through which light passes into the camera

Aperture also controls depth of field (DOF), which refers to how much of your image is in focus. A wide aperture (small #) will give a shallow DOF and can be used to isolate a subject.

ISO is the level of sensitivity of your camera to available light. Typically ranges from 100-1600 Newer Digital cameras have a higher range (up to 64000)

An Image Histogram is a type of histogram that acts as a graphical representation of the lightness/color distribution in a digital image.

White balance is to get the colors in your images as accurate as possible.

JPG VS RAW

Imagine the frame divided into three equal sections both horizontally and vertically Divided into thirds The Concept is: Placing your subject or elements along any of these lines, and especially on or near the intersecting points, makes a photo more naturally attractive to the viewer.

The Rule of Thirds

Rule of Thirds The concept is simple: Place subjects along the lines, or near intersecting points For portraits, the eyes are often positioned along one of the horizontal lines preferably near one of the power points to make the photograph more pleasing to look at, and naturally draw attention to the eyes. For landscapes the horizon is aligned to any of the horizontal lines depending on how much land/water/sky you want to show.

Tips for Great Pictures

1. What story am I telling? 2. What is the visual focal point of this shot? 3. What competing focal points are there? 4. What is in the background and foreground? 5. Am I close enough? 6. What is the main source of light? 7. Is my Framing Straight? 8. What other perspectives could I capture this subject from? 9. How would holding the camera in the other format change this shot? 10. How will the eye travel through this image?
