### How to Expose

1. 1. How to make an Exposure The Trinity and Beyond
2. 2. White Balance <ul><li>AWB-auto white balance </li></ul><ul><li>Daylight </li></ul><ul><li>Shade </li></ul><ul><li>Cloudy </li></ul><ul><li>Tungsten </li></ul><ul><li>Flourescent </li></ul><ul><li>Flash </li></ul><ul><li>Custom </li></ul>
3. 5. The Trinity-Aperture <ul><li>Controls how large the opening is that lets light through to the sensor </li></ul><ul><li>Called f-stops </li></ul><ul><li>Full stops </li></ul><ul><ul><li>1,1.4, 1.8, 2.0, 2.8, 3.5, 4, 5.6, 8, 11, 16, 22,32 </li></ul></ul><ul><li>Controls depth if field </li></ul><ul><li>The higher the number the smaller the aperture hole is </li></ul><ul><li>The higher the number the more depth of field </li></ul><ul><li>To change the aperture press the AV button while scrolling with the main dial </li></ul>
4. 7. Depth of Field
5. 8. The Trinity-Shutter Speed <ul><li>Controls how long light passes through to the sensor </li></ul><ul><li>Change shutter speed with main dial </li></ul><ul><li>Can be anywhere from 1/4000 second to 1 second to minutes </li></ul><ul><li>1/500=one five hundredth of a second </li></ul><ul><li>1” = one second </li></ul><ul><li>Anything under 1/60 will have motion blur from your hands shaking (called camera shake) </li></ul><ul><li>Bulb setting-shutter stays open as long as you press the button </li></ul>
6. 9. Fast Shutter Speed
7. 10. Slow Shutter Speed
8. 12. ISO <ul><li>Controls how sensitive your sensor is </li></ul><ul><li>Runs in multiples </li></ul><ul><ul><li>50, 100, 200, 400, 800, 1600, 3200 </li></ul></ul><ul><li>100-400 for bright light </li></ul><ul><li>400-800 for less light </li></ul><ul><li>1600 for very dark situations </li></ul><ul><ul><li>After 800 you begin to have lots of noise </li></ul></ul><ul><li>Your ISO will affect the choices of aperture and shutter speed available to you </li></ul><ul><li>A higher ISO will allow you to use faster shutter speed </li></ul>
9. 13. Add all three and you have an Exposure <ul><li>Now we have to combine all three to make our exposure </li></ul><ul><li>Set your white balance </li></ul><ul><li>Set your ISO </li></ul><ul><li>Make choices about aperture and shutter and use your light meter to get the correct exposure </li></ul>
10. 14. Light Meter <ul><li>Measures the light coming into the camera </li></ul><ul><li>This measurement allows you to choose the correct aperture and shutter speed </li></ul><ul><li>Press the shutter release half way down to get a light meter reading </li></ul><ul><li>The goal is to get the blinking bar in the center of the light meter bar </li></ul><ul><li>Choose a aperture or shutter speed that you want to start with and then then scroll with the other (aperture or shutter speed)until you have the bar in the middle </li></ul>
11. 16. Underexposed Overexposed
12. 20. Summary of Making an Exposure <ul><li>Set your white balance </li></ul><ul><li>Set your ISO </li></ul><ul><li>Choose your shutter speed or aperture </li></ul><ul><li>Use your light meter to get the corresponding shutter speed or aperture </li></ul><ul><li>Take the photo and check your LCD to see if it is properly exposed </li></ul>
