This is the camera application that can regulate focus after taking pictures.
You may say good-by to the out-of-focus.
All you have to do is setting the interval of focus length and just pressing shutter.
You take pictures many times without worrying about focus so much and save them,
and then you can choose and get the photos that the focuses match afterward.
The photo which you chose can be stored to the camera roll, emailed or uploaded to SNS easily.
You can also record scenery of a wide range like a panoramic photograph by swinging the camera slowly to the side in fixing focus mode.
Focus modes are as followings,
Far - restricting far range focus
Med - restricting middle range focus
Near - restricting near range focus
All - all range focus
Fit - around auto-focus range
Fix - just auto-focus point

When you choose the front camera, it does not become the focus-free.
