Focus stacking is similar in principle to HDR. However, with focus stacking, images are captured with different focus points, and later combined in software, to create an image with more DOF than would be possible with a single exposure. Landscape and macro photography are two genres of photography that benefit most from using this procedure.

Focus Stacking Setup
Important Notice: Please set your lens to Auto Focus (AF) mode for Canon and Nikon.
When you open Focus Stacking Mode, you will see the following screen. You should set 2 Focus Points (near and far focus positions) and Frame Count in order to start the mode.
Firstly, select your first focus point using incremental focus buttons (<- and ->), Touch Focus on liveview screen or focus ring of your lens. Once you adjust your first focus point, touch Point 1 circle to set this point. When Point 1 is defined, you will see that Point 1 will be colored as below.
Secondly, adjust your far focus position by using incremental focus buttons (<- and ->). It is important that you should not change the focus point by touch focus or manually using focus ring of your lens. When you finish adjustment of second focus point, touch Point 2 circle to set this point. When Point 2 is defined, you will see that Point 2 will be colored as below.
Now, you can touch Point 1 or Point 2 to see the scene and focus point in your liveview. If you completed the selection of focus points, you can define the frame count by touching Frame Count label on the screen. Once you touch it, a parameter screen like below will be opened.
Set one of predefined Frame Count and touch OK. You are ready to start capturing by touching Play icon.
Let's summarize the process:
- Adjust the near focus position – use incremental focus buttons (<- and ->), Touch Focus or focus ring of your lens
- Touch the “Point 1” icon to set first focus point
- Use only the incremental focus buttons to adjust the focus to the farthest point
- Touch the “Point 2” icon to set second focus point
- Adjust Frame Count
- Press “Play” icon to start the focus bracketing process
