4 Simple steps to calibrate ON fixed lenses (Win)
(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 software you select the ‘cali-
bration’ image and click on the “Generate…” button
(the LCC tool is located under the white balance tab).
3. Give the cali-
bration 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 set a checkmark in
the “Apply LCC for next Captures”.
If working with large format cameras with tilt and
swing, you would have to make a new calibration file if
you change the tilt and swing position.
When using LCC in combination with large format cap-
ture and image stitching you must capture one cali-
bration file per image and make sure that you match
the calibration file to the right image prior to stitching.
