Focus Stacking

A new focus stacking method is available which automates more of the process. Changing to
the previous focus stacking method is still possible by turning on "Classic Focus Stacking" in
the settings. The new focus stacking method requires to user to specify the nearest and
furthest focus points and then the CamRanger automates the step size and number of shots
based on the camera, lens, and aperture. Because the aperture affects the depth of field, this
focus stacking method can only be used when the camera is in manual or aperture priority
exposure modes.
Point 1 is the nearest focus point and point 2 is the furthest away. The points are set by
pressing the respective "Set" button when the focus is at the desired point. To set the first
focus point any focus adjustment method can be used. However, after a point has been set
only incremental focus adjustments can be used. Touch focus or manual lens cannot be used
as there is then no way to track the focus changes that have been made. If one of these
methods is used to change focus then any focus points that were set may be automatically
cleared.
Once the two focus points are set, pressing the bullseye button will move the focus to that
position. It will not be able to achieve a cinematic quality follow focus, but can be useful to
return the lens to a particular focus point. Pressing clear with clear that focus point so it can
be reset.
After the focus points are set, the Start button will enable and pressing it will start the focus
stacking process.
