1. Digital Photography

2. Photography Triangle

3. Shutter Speed Speed at which the film or sensor is exposed to light Usually a fraction 1/250 = 1 250 th of a second

4. 30 Second Exposure

5. 3 Second Exposure

6. 1 second exposure

7. Aperture The size of the opening of the lens Tricky because the numbers are opposite of what they should be –F4 allows more light than F22 Each F-stop is equal to ½ of the previous F-stop -F4 to F5.6 allows twice as much light in

9. Aperture & Depth of Field Depth of field – how much of the image will be in focus –Low depth = closest object is in focus –High depth = most of the image is in focus –Low aperture = Low field –High aperture = High field

10. F/5.6 F/32 Low depth of field High depth of field

11. ISO Think of ISO settings as worker bees –ISO 100 = 100 worker bees –ISO 200 = 200 worker bees The worker bees gather the light The more bees you have slower the shutter speed necessary but the more grainy the picture will be

12. ISO Difference ISO 100 ISO 1600 Zoomed In
