Recording guide line
When you align the subject on the horizontal
and vertical guide lines or the cross point of
these lines, you can take pictures with
well-designed composition by viewing the size,
the slope and the balance of the subject.

About the Histogram
A histogram is a graph that displays brightness along the horizontal axis (black to white)
and the number of pixels at each brightness level on the vertical axis.
It allows you to easily check a picture’s exposure.
1
Dark areas, mid-tone, and bright areas are balanced out evenly, making it suitable to
take a picture.
2
The picture will become underexposed with more dark area. The pictures with mostly
dark areas, such as night scenery, will also have a histogram like this.
3
The picture will become overexposed with more bright areas. The pictures with mostly
white areas will also have a histogram like this.
