Modern Digital Photography involves many different units of math. This includes Geometric Sequences, Polyhedrons, Fractions, Geometry, Circle Areas, Angles, Algebra Formulas, and Symmetry. Understanding these different units of math can make a better photographer. Having a grand knowledge of this will allow the photographer to know the best viewpoints, angles and geometric composition.
Digital cameras are usually preset to a auto mode which will work well for most situations. The best way to use a camera is to put it in manual mode and use mathematical problem solving. Using the manual mode will allow the photographer to have full control over the settings used when taking a picture.

The eight most important mathematics tools to photography are:
- Photo Composition Rules
- Digital Camera Variables
- The ISO Variable
- The Aperture Variable
- The Shutter Speed Variable
- The White Balance Variable
- Combining Variables for Correct Exposure
- Flash Photography and Diffusers
Photographic composition is the basics of what the photograph will look like. Rule of Thirds is one of the most commonly used methods in photography. The theory behind this is to place the point of interest in the position of a third of a picture. This allows the photograph to be interesting and also have a place to follow. Balancing elements is also a very common use of composition. Placing the main subject of your picture off the center will create an interesting photo. Leading lines is one of the most interesting compositions because your eye is naturally drawn to lines. By having leading lines, it can affect the way a viewer sees the photo. Symmetry and patterns will be a more natural photo. Depth is also a very important aspect to have when taking a photograph. If the picture is two-dimensional, it will loose depth. When you have an ongoing image that overlaps, it will create a better visual. The human eye can recognize layers and separate them out.
Digital camera variables help adjust the photograph. The variable changes the value to a different numerical setting. There are several variables that can be changed on a Digital Camera. These variables are aperture, shutter speed and ISO. Aperture is how wide the hole leading from the lens. This can affect how much light is able to enter the camera. It can also create blurred backgrounds for photographs. Shutter speed determines how quickly the inside of the camera opens and closes to let light get to the sensor. ISO is the sensitivity to light that the pixel sensor is set to. Another variable to consider is white balance and color temperature. White balance controls the amount of white the is captured in the photograph. These conditions that may cause this can be shade, and indoor orange/yellow lighting.
The ISO variable works as a brightness control on the camera. The ISO is an adjustment that can be made based on lighting situations. ISO settings in a camera include 100, 200, 400, 800, 1600, 3200, etc.. The higher numbers mean that the sensor is more sensitive to light. Each time the number doubles, it is twice the sensitivity.
The aperture variable works isolate subjects in portraits and get full detail in landscapes. The aperture scale consists of odd set decimals and whole numbers. On the camera, aperture is the setting of F. F represents F-stop. The scale moves from F1.4 to F2, F2.8, F4, F5.6, F8, F11, F16, F22, and F32. As f-numbers go up in value, the circular aperture opening goes down in value.
The shutter speed variable is used for creating dramatic effects. Understanding how to use shutter speed will be important in the ability to have in focus pictures without any motion blur occurring. Shutter speed is very important in situations with fast moving sports action, dimly lit indoor areas, night time photographer, theater and musical performances, indoor photos that use flash, bird and wildlife pictures, photographing young children, and photos where the photographer wants motion blur for fast moving objects. Every digital camera has a shutter that opens and closes quickly to let light through the lens. When you start the camera by taking a picture, the shutter will open and close immediately. The speed at which the shutter opens and closes, it is usually a fraction of a second. This can include ⅛, 1/15, 1/30, 1/60, 1/125, 1/250, 1/500, 1/1000, and 1/2000. The larger the number, the faster the shutter speed.
The white balance variable is used so the photographers can obtain pictures that have realistic coloring. There is a scale of color temperature and a range of camera settings to be matched. The positive and negative amounts can let us add more of the opposite color and counteract certain color aspects like tint, hue or cast. If white balance is not acknowledged, it can make the picture have unpleasant coloring.
Combining variables for correct exposure will tie together the digital camera variables. When these variables are unified together, the picture will be nice and clear. Underexposure in photographs can result in dark and dull images. This is because there was not enough light recorded from the digital sensor. Overexposure in pictures makes the image washed-out. This is because there is too much light hitting the digital sensor. The correct exposure will allow the tone in the image to range from white to black. This picture will be crisp and bright.
Flash photography and diffusers help the use of light in the photo. Diffusers come in all shapes and sizes for a variety of uses. Diffusers create a softened light. Most digital cameras have built in flash that provides an intensely bright light. These flashes do basic things. Diffuser helps bring in light but also color to the picture.
