FOCUS BRACKETING
Focus Bracketing can be used for different purposes. The
most obvious is to achieve a larger depth-of-eld by stacking
images with different focus positions together in post-produc-
tion. You can also use it to pick the best image from a batch.
In Focus Bracketing mode, the camera will automatically
take a pre-set number of images and calculate focus shift
between each capture. The images will be stored on the card
as separate les and you can edit them manually or use a 3rd
party software (e.g. Helicon Focus™) to merge them together
into a nal stacked image.
It is difcult to give detailed guidelines on which settings to
use, but look at the examples in this section as a starting point
for your own experiments.
The camera offers three different modes in which the images
will be taken.
1 Towards Innity
Set focus manually or by using AF. If AF is used, remember
to deactivate it before starting the sequence. In this
mode, focus should be set on a point ( A ) that is closer to
the camera than the main subject. When the sequence
is started, focus will be shifted towards innity until the
sequence is nished or the lens reaches innity position.
2 Symmetric
In this mode, focus should be set on the main subject ( B ).
When the sequence is started, the camera will rst take an
image and then move to a focus point closer to the near
limit and take all the images in the sequence, shifting focus
towards innity. The rst image is an extra exposure made
to ensure that there is one image of the main subject with
perfect focus.
3 Towards Near Limit
Set focus on a point ( C ) behind the main subject. During
the sequence, the camera will shift focus closer and closer
to the camera. The sequence will stop after the pre-set
number of images has been captured or the lens has
reached near limit.
