To adjust the optical offset, add the Optical Offset icon to the Menu Bar (see
Rearrange Menu, page XX) then tap it. The Menu Bar will be hidden, and a depth
scale will be displayed.
Bands in shades of blue represent the near refocusable range, and bands in
shades of orange represent the far refocusable range. The current optical offset
position is indicated by a white band (the default position is -4). Rotate the front
dial to relocate the optical offset closer or further away in the refocusable range.
To close the depth scale, unhide the Menu Bar by swiping left from the right edge
of the screen. The optical offset will remain at the new setting until it is changed
using these same steps.
Spot Depth Feedback
Spot Depth Feedback allows to check the distance of the object at the center of
the live view. Press the Lytro button halfway to activate it. A light blue band will
appear on the Depth Assist Bar, representing the distance of the object from the
camera. It is then easy to see if the object falls within the focusable range,
indicated by the orange and blue Focus Steps. Activating Spot Depth Feedback
does not affect the focus of the camera.
Depth Histogram and Depth Overlay
The LYTRO ILLUM offers live, interactive depth analysis in the form of the Depth
Histogram and Depth Overlay. Both provide feedback on where subjects fall
relative to the refocusable range. To activate them, fully press the Lytro button.
The Depth Histogram consists of bands extending out to the right of a depth
scale. Bands in shades of blue represent the near refocusable range, and bands
in shades of orange represent the far refocusable range. The more there is
available to refocus on at a given depth, the further the band beside it will extend
to the right.
Glancing at the histogram can tell if you have a substantial subject within the
refocusable range. To maximize the impact of refocusing, it is ideal to have a
significant histogram wave in both the near refocusable range and the far
refocusable range. Waves outside of the refocusable range correspond to objects
in the background or foreground that can not be refocused.
The Depth Overlay provides the same kind of information as the Depth
Histogram, but displays it as an overlay on objects in the live view. Objects that
fall within the near refocusable range are edged with blue. Objects that fall within
the far refocusable are edged with orange. Instantly see whether there is enough
subject matter in each of the ranges to provide good refocusing possibilities.
