Canon PowerShot G12, Shadow Correction and Dynamic Range (DR) Correction

0
319

Your camera provides two functions that can automatically make your pictures look a little better: Shadow Correction and Dynamic Range (DR) Correction. With Shadow Correct, the camera evaluates the tones in your image and then lightens any areas that it believes are too dark or lacking contrast after you take the shot (Figures 10.10 and 10.11). Dynamic Range Correction works in the other direction, attempting to prevent highlights from blowing out to white. The Correct modes work only when shooting JPEG images (not RAW or RAW+JPEG).

The two controls are accessed from the same menu, even though they perform opposite actions.

Without Shadow Correction, the shadows on the chair and the fireplace are dark.
