OM System cameras have focus stacking a unique function, which is useful to increase the depth of field in macro photography. But there is another use case for focus stacking, even though the depth of field normally isn’t an issue.
When is focus stacking helpful for landscape photography?
A popular creative means in landscape photography is to place an object in the foreground as this emphasises depth. Always when you do this depth of field becomes relevant in landscape photography, even though wide-angle lenses have a much bigger depth of field than tele lenses. But in landscape photography the distances are enormous. Therefore closing the aperture doesn’t help. Especially as image quality is getting worse when you use a smaller f-stop than 11.
What to consider when using Focus Stacking
In my article “Focus Stacking and Focus Bracketing” I write about the needed settings in detail. In opposite to macro photography you have to consider a bit more. As already said above you should avoid smaller apertures than 11. In case you close it further diffraction will decrease your image quality. In addition, most properly you must experiment a bit with the step size. Which one is fitting depends on the lens, focusing distance and aperture. Therefore a recommendation is hardly possible.
Focus Stacking takes the first image on the focus point you have set. The next image is taken from a closer point and the following will be taken behind the first focus point. Therefore you should not fonearestthe the closest distance which should be sharp, but behind. Also here you must experiment to get the result you would achieve.
