3. Exposure and Dynamic Range Low contrast | High Contrast

4. Histogram: plots pixels according to brightness: L-R, Dark-Bright Low contrast: Most pixels in middle, few very dark (shadows) or very bright (highlights) areas. Result: Flat, boring picture. No defining characteristics.

5. Histogram: plots pixels according to brightness: L-R, Dark-Bright High contrast: More pixels toward edge, in very dark (shadows) or very bright (highlights) areas. Result: Interesting, dynamic picture. Sharply defined characteristics.

6. Histogram: plots pixels according to brightness: L-R, Dark-Bright Low contrast: Most pixels in middle, few very dark (shadows) or very bright (highlights) areas. Result: Flat, boring picture. No defining characteristics. However, low contrast can always be edited into a high contrast image

7. Low contrast High contrast High contrast has caused this area to be completely white, destroying all detail. It is impossible to get this detail back – this is known as a “blown highlight”.

8. Low contrast High contrast High contrast has caused this area to be completely black, destroying all detail. It is impossible to get this detail back – this is known as a “crushed shadow”.

9. When the photowell is full, a white value occurs. No photons after this are recorded, so all detail for these pixels are lost. If the electron count is below a certain threshold, it is just recorded as black. So if there aren’t enough photons, all the detail in those pixels is lost. DynamicRange

10. Large dynamic range: very bright and very dark areas in same scene

14. The camera has a limited dynamic range. Thus it can only capture a certain portion of the total dynamic range of the scene.

15. Portrait Assignment Focus on the following elements: Lighting (direction, intensity) Vantage point (camera direction, setting, background) Perspective (subject distance vs. focal length) Depth of field Directing the subject (poses, props, expression) Before shooting: Login to the gallery, choose 2 photos and evaluate each of these elements What was done, how it worked out, and how you would do it
