I find that a setting of 3 works well, so I leave it at that. Change any of these and your depth of field changes as well.

There are too many variables at play for depth of field - the lens, focal length, distance to subject, and aperture. I am often asked if each FD can be translated into a quantifiable depth of field. The greater the focus differential setting, the more the focusing element in the lens moves between shots.

Focus Differential - 3 This seems to be the sweet spot so I never change it.

Number of bracketed shots - 8 This is usually ample and you could get away with fewer.

Focus Point - single point, positioned over your closest foreground object.

Aperture - usually between f/5.6 and f/7.1.

ISO - 200 Depending on lighting conditions I may increase the ISO, but I never use AutoISO.

Mode - Aperture Priority (almost all of my landscape images are shot in A).

It has a minimum focusing distance of 20cm and a field of view of up to 115°. Regardless of which OMD camera body I happen to be using, my goto lens for this type of photography is the 7-14mm f/2.8 PRO. As mentioned earlier a tripod can be useful, but to be honest, the image stabilization of the OMD line-up is so good that I often forego the tripod. This will give me the field of view needed to capture the foreground, horizon and sky.

Many of these images were also shot in vertical orientation and with the camera tilted down at about a 45-degree angle. If you run Helicon Remote and connect your camera to your computer, the application can automatically adjust your cameras focus and take the images you need to.

For many of the images in this article the front lens element was about 6 inches away from the foreground subject. I opt to use focus bracketing/stacking when the foreground lacks larger points of interest and I want to accentuate the details of smaller foreground subjects like ice crystals, sea shells, small rocks, leaves, flowers, etc. Here is a breakdown of how I go about using this feature. Although the scene may be substantially different from one location to another, the method by which I use focus bracketing/stacking remains fairly consistent.
