Exposure lock

When you cannot achieve an appropriate exposure because of a strong
color contrast, lock the exposure and then capture a photo.
To lock the exposure, adjust the photo's composition on which you
want to calculate the exposure, and then press the custom button.

After locking the exposure, aim the lens where you desire, and press
