Calibration (LCC). By holding an opal white plate in
front of the lens and capturing a calibration image that
you then apply to all of your capture files you are able
to remove the lens cast.
On medium format cameras the calibration is very
simple: You do one calibration for each lens and then
save the calibration files and apply them when needed
by clicking “Set as default for new Captures”.
4 Simple steps to calibrate on fixed lenses (Mac)
(no zoom, tilt or swing).
1. Hold the calibration plate in front of the fixed lens (as close as
possible), and capture. In order to ensure correct exposure you may
have to open up a few f-stops or in a very dark setup, put on more light
directly onto the plate.
2. In the Capture One soft-
ware you select the ‘calibration’
image and click on the “Save
LCC” button
(the LCC tool is located under the
grey balance tab).
3. Give the calibration file
a name that corresponds to the
lens in use or the set-up (e.g.
45mmDaylight)
4. Select the calibration file:
“45mmDaylight” from the “Lens
CC” drop-down list and click “Set
as default for new Captures”.
