How to Use Canon G12’s Dynamic Range and Shadow Correction When Taking Pictures

The Canon Powershot G12 has two functions - the Dynamic Range (DR) Correction and the Shadow Correction that can enhance your pictures quality automatically. The Shadow Correction works by lightening any area that the camera evaluates as lacking contrast or too dark after you have taken the shot. On the other hand, Dynamic Range Correction works in the opposite way, by trying to prevent highlights from fading out to white. These Correct modes are only applicable when you’re shooting JPEG images.

Procedure in Using DR and Shadow Correction

Use the same menu to access the two functions which perform in opposite ways.

1. Press the camera’s Function/Set button.

2. Search for the Dynamic Range (DR) Correction menu which is only above white balance setting, using either the Up or the Down buttons.

3. Check if the camera is set to auto mode. Then, enable Dynamic Range (DR) Correction by pressing the Left or Right button to select Auto 200% or 400%. Choosing the higher setting will result to more correction.

4. Enable Shadow Correction by pressing the Display button. Then, push the Left or Right button to select Auto setting.

5. Set back to shooting mode by pressing the Function/Set button.

How to Use Canon G12’s Locking Focus When Shooting a Scene

In taking images, a Canon Powershot G12 by default, focuses on whatever is centered on the screen. However, you can adjust the focus manually by pushing the Manual Focus (MF) button down. Then, turn the Control dial.

Once it’s manually-set, the focus is not adjusted even if the subject is no longer centered or is no longer within the camera range. This is one disadvantage of using a Canon G12 in shooting a video. To compensate, the camera adjusts the exposure level as you record which can be a distraction. To avoid the problem, adjust and lock manually both the exposure level and the focus before recording.

Locking the Exposure Level and Focus

• Set the camera into Movie mode. Once the desired exposure level is attained, push the camera’s asterisk (*) AE Lock button.

• Looking at the exposure shift, adjust the exposure levels in increments of one-third steps using the Control dial.

• Begin recording by pressing the shutter button or press again the asterisk (*) AE Lock button to unlock the exposure setting. If you have started recording, the exposure setting can’t be adjusted manually.
