[quot]Stack focus
This selection will shoot a series of photographs with varying focus points. It is used in macro photography to assemble sharper final images by merging photos where each has a different focus point.
This function can also create scripts named like named FST_1234.SH, which can be used for stacking the images with enfuse. See Exposure bracketing for details on how to use these scripts, and the focus stacking section from Enfuse reference manual. To enable (or disable) the post-processing scripts, go to HDR bracketing submenu.
Usage:
Configure rack focus and use it to preview the focus range.
Select the number of focus steps to skip. This will determine the number of pictures to be taken.
Press PLAY to start the focus sequence (PLAY mode) or take the first picture (SNAP mode).
You can also combine this function with HDR bracketing and silent pictures.
Recommended focus step settings: same as for rack focus. [/quot]
