8.7 4 simple steps to calibrate on fixed lenses (PC)
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 ‘calibration’ image and
click on the “Generate…” button (the LCC tool is located under the
white 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: “45mm Daylight” 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 capture and image
stitching you must capture one calibration file per image and make sure
that you match the calibration file to the right image prior to stitching.
