Brightness: Exposure compensation
The camera automatically determines the aperture
value and shutter speed according to the
brightness level. This is known as auto exposure.
However, auto exposure alone may not result in
pictures of your expectations. At times like this, you
can adjust the exposure through increasing or
decreasing the exposure value set by the camera’s
auto exposure during shooting.
Increase the exposure when you want the dazzling sensation of the summer
beach or the whiteness of the snow to stand out. And decrease the exposure
when the area to be shot is smaller and brighter compared to its surrounding
area. If you are unsure how much exposure compensation is required, it is
better to take the picture with various settings.

Color: White balance
There are other sources of lighting like tungsten light and fluorescent light,
besides the sunlight, illuminating the subject. Unlike the sunlight, these lights
contain particular colors. Hence, the same white object shot under different
lighting conditions turns out in different colors. Even for sunlight, the outcome
differs depending on the sky conditions, shadow of trees or buildings etc.
White balance automatically corrects the effects from these lighting and
enables shooting with the right colors. Though the right colors can be obtained
when the white balance is set to [AUTO], depending on the shooting
situations, it may not be possible to get the intended colors. In such cases,
change to an appropriate setting.
