Aperture & Depth of Field

1. Standard Aperture/F-stops-
                  -the ratio of the focal length of the lens to the diameter of the aperture

2. Aperture Priority-
   a camera mode that allows you to select the aperture in over the available range and have the camera calculate the best shutter speed to expose light correctly
3. Ambient Light-
   natural, available light that’s not added by the photographer
4. Artificial Light-
   light that comes from man-made light source
5. ASA/ISO/Film Speed-
   - ASA 'American Standards Association' responsible for supplying the speed rate that measures the degree to which film is sensitive to light
   - ISO 'International Organization for Standardization' film speed ratings are used it indicate the relative amount of light necessary to give proper exposure
   - Film speed is the measure of a photographic film's sensitivity to light
6. Bracket- 
                 -means to take multiple photos of the same scene with different exposure settings. 
7. Depth of Field-
   amount of a photo that will be in focus
8. Exposure Triangle-
   

    - each three aspect of the triangle relate to light and how it enters and interacts w/ the camera
                 -  the three elements, ISO, Aperture, and Shutter Speed, that if one iso was changed it effects                  both shutter speed and aperture for the photo; if either Av or shutter speed were modified it will only effect themselves and not iso
9. How to Control Depth of Field-
   

   -  Large Av will decrease DOF and a small Av will make a large DOF

   Large aperture (remember it’s a smaller number) will decrease depth of field while small aperture (larger numbers) will give you larger depth of field.

10. Light Meter-
    -a sensor used to measure light and indicate the ideal exposure settings

Find examples for your journal label each image and guess the aperture settings used on the camera.

Journal: Shutter

Shutter

1. SLR -  SLR, which stands for single-lens reflex, refers to a type of camera that employs a rotating mirror (either a pentaprism or a pentamirror) that reflects the image that comes through the lens onto a focusing screen.
2. TLR - Twin-lens reflex, a camera with two lenses the upper one is the viewfinder lens that has a mirror reflex view and the bottom one is the taking lens.
3. Shutter -  what determines the duration the sensor is exposed to light.
4. Shutter Speeds - the time for which the shutter exposes the film, typically a small fraction of a second. 
5. Bulb - that keeps the shutter open for as long as the shutter release is pressed 
6. Cable Release - a cable that screws into the camera (on film camera bodies usually into the shutter release, on digital bodies elsewhere) so the shutter can be fired remotely with minimal shake.
7. Tripod - a camera accessory that consists of three legs that support a platform on which photographers can place their cameras.
8. Light Meter- a sensor used to measure light and indicate the ideal exposure settings.
9. Bracketing- is the technique of shooting a number of pictures of the same subject and viewpoint at different levels of exposure. 
10. Hot Shoe- is a mounting point on the top of a camera to attach a flash unit.

Find image examples of the following for your journal and guess what shutter speed was used to create the photo:

1. Slow Shutter Speed         f-4

2. Fast Shutter Speed             f-1000

       3.Panning                             f-125

4.Painting with Light                        f-125

5.Multiple Exposures                     f-500
