Creating an LCC profile in Capture One
1. Once you have made an LCC reference capture, select the RAW file in
Capture One. Go to the
Lens Correction
tool and select the correct lens from
the
Profile
menu. Then select the
Movement
tab. Make sure that the metadata
Focal Length
,
Aperture (f)
,
Shift x
, and
Shift y
is correct. Otherwise, enter the
correct values.
2. For future reference, it is always a good idea to rename the LCC file, so you
can easily recognize it later by naming it for example “35mm_+10shift_f11”.
3. Go to the
LCC
tool and click on
Create LCC
.
4. Enable the
Include Wide Angle Lens Correction Data
option if you are
using a wide-angle lens and some degree of movements with a tilt or shift
lens. This option initiates a special LCC process that is designed to correct for
banding at the extreme edge of the image circle on higher resolution digital
backs. You can also enable the
Include Dust Removal Information
option to
create a map which automatically removes dust. Note that this will increase
processing time and negates future use of the LCC.
5. Click
Create
in the dialog box. Capture One now analyzes the reference
image and creates an Lens Cast Correction.
6. When completed, the reference image used will be labeled LCC in the
Browser. The created Lens Cast Correction will be applied automatically to the
reference shot, letting you check immediately whether it was successful. It
should show an evenly exposed light grey image without a color cast,
vignetting or dust spots (if you have selected that option). It may be
necessary to adjust the white balance of the image to evaluate the proper
application of the LCC.
Workflow tip:
If you have multiple LCC reference shots to calibrate, you can
save time by selecting them all and click on Create, then Capture One Pro will
work through them one by one.
Applying an LCC profile
You apply an LCC profile to an image by first selecting the LCC reference shot
and then the image in the Browser, next go to the
Adjustments
menu and
select
Apply LCC
. You can also right-click on the image in the Browser and
select
Apply LCC
. Notice how the used LCC profile file name is shown by
Profile
.
Workflow tip:
You can select multiple images and apply one LCC profile to
them all by using the same process.
Adjusting the LCC profile e
ff
ect
Once an LCC profile has been applied, you can fine-tune its e
ff
ect on the
image with the LCC tool. You can turn the color cast correction on and o
ff
with the
Color Cast
option as well as the
Dust Removal
if any dust was found
on the reference image. You can also control the correction of
Light Fallo
ff
with
Enable Uniform Light
and the
Uniform Light
slider. You might, for
example, want to dial the correction down a bit to 75% with the slider in order
to retain some of the light fallo
ff
for artistic reasons.
