Intro ductio n
Chapter 1:
Introduction
The CyberLink PhotoDirector Lens Profile Generator is a tool that lets you generate
your own custom lens profiles. These lens profiles can then be exported to
CyberLink PhotoDirector and used to correct photos shot with the same camera
lens. You can also share lens profiles on DirectorZone so other users that have the
same camera lens can also correct their photos using your custom lens profile.

Chapter 2:
Shooting the Required
Images
Before you can generate a lens profile, you must first shoot a number of images
using the camera and lens you are generating the lens profile for. This section will
guide you through all the steps required to shoot these images, and also outline
the recommended camera and shooting settings.
Selecting and Printing a
Calibration Chart
The first step is to select and print out one of the calibration charts that were
included in the CyberLink PhotoDirector Lens Profile Generator installation. You
can find the calibration charts in the following folder on your computer: C:
\Program Files\CyberLink\Lens Profile Generator\Calibration Charts
Note: folder path may differ if you changed the install location during installation.
It is recommended that you:
1.
Select and print out the largest calibration chart you are able to print and
which contains the most squares. The more squares there are, the more data
points available for the CyberLink PhotoDirector Lens Profile Generator.
2.
Print the calibration chart on a white, non-glossy paper.
3.
Mount or frame the printed calibration chart, as demonstrated in the below
photo.
3
CyberLink Pho to Directo r Lens Pro file Generato r
Shooting Environment Setup
Once you have your calibration chart printed, tape it to a wall or place it on an easel
in a room where the lighting will stay consistent during the shoot.
For the best results, it is recommended that you use two photography lights if you
have access to them. The below diagram suggests the recommended environment
setup you should use if you have access to two lights.
Below is an example photo of the ideal environment for shooting calibration
images.
Note: please note that the use of photography lights is not required to shoot the
calibration chart images.

Shooting the Images
After you have printed the calibration chart and set up your shooting environment,
you are ready to start shooting the images. The shooting process is the most
important step in creating a lens profile, but this user guide provides you with lots
of shooting recommendations to ensure you achieve the best results.
Number of Images Required
Once you are ready to shoot the calibration chart images, you must first decide
how many image sets you want to shoot. Planning how many image sets you will
shoot before you begin will help you achieve the best results. There are many
determining factors, but ultimately the number of image sets you decide to shoot
is up to you. Just remember that the more image sets you shoot, the better the
resulting lens profile will be at correcting photos in CyberLink PhotoDirector.
What is an Image Set
An image set is a group of images shot with your camera and its lens using the
same settings. Each image set consists of a number of images that where shot at
5
CyberLink Pho to Directo r Lens Pro file Generato r
the same focal length, aperture, and focus distance. When you change one of these
settings, you have then created a new image set.
The Number of Images in an Image Set
An image set is composed of a number of images shot with the same camera
settings. For each image in the set, the calibration chart should only take up a
portion (1/4 to 1/2) of the frame. You need to change the position of the calibration
chart in the frame for each image, and ensure none of the squares get cut off.
A minimum of four images is recommended to create a set, but as many as nine
images can be shot. The following is an example of an image set that contains four
images. Notice that each image positions the calibration chart in the corner of the
frame, and all the squares are showing.
The following are the recommended calibration chart positions for an image set
with nine images.

Sho o ting the Required Im ages
Number of Image Sets
The total number of images sets you shoot depends on what apertures and focus
distances you choose to use. The following are our recommendations to achieve
the best results.
Focal Length
A lens profile should include images shot at each focal length your lens supports.
For example, if you have a 50mm prime lens, you only need to shoot at the one
focal length your lens supports. If you have a 16-35mm zoom lens with the focal
lengths of 16mm, 20mm, 24mm, 28mm, and 35mm, then you should shoot at each
of these five focal lengths.
Aperture
In order to take a good aperture sample for your camera lens, shoot images from
the wide open aperture position (lowest f-number) to two full stops down from this
position (i.e. each of the first seven f-numbers). Then shoot at one stop increments
(i.e. every third f-number) until you reach the minimum aperture (highest fnumber).
As an example, if you are shooting with a 50mm f/1.4 lens with the following
apertures, you should shoot at each of the apertures indicated in red.
Focus Distance
To get a good focus distance sample of your lens you must first determine what is
the minimum distance it supports. Denoted as M below, it is recommended that
7
CyberLink Pho to Directo r Lens Pro file Generato r
you shoot at the following focus distances:
M (minimum focus distance for the lens)
2xM
4xM
(infinity)
Total Number of Images (Recommended)
Based on the examples used above, the following would be the recommended
total number of shots you should take of the calibration charts:
Note: please note that the recommended focal length numbers below are not fixed
numbers you should use as a guideline. The focal length number you should use
to calculate your total image number should equal the number of focal lengths for
your specific lens.
50mm prime lens
1 (focal length) x 13 (aperture) x 4 (focus distance) x 4 (four corners) = 208 images (52
image sets)
1 (focal length) x 13 (aperture) x 4 (focus distance) x 9 (nine corners) = 468 images
(52 image sets)
16-35mm zoom lens
5 (focal length) x 13 (aperture) x 4 (focus distance) x 4 (four corners) = 1048 images
(260 image sets)
5 (focal length) x 13 (aperture) x 4 (focus distance) x 9 (nine corners) = 2340 images
(260 image sets)
Note: please note that you do not have to shoot the recommended number of
images to generate a lens profile. However, the more image sets you capture, the
better the resulting lens profile will be and the more effectively it can correct
images taken with the lens.

Recommended Camera and Shooting
Settings
To ensure you get the best images possible for the CyberLink PhotoDirector Lens
Profile Generator, the following are the recommended camera and shooting
settings you should use. Also, if you receive any errors during the generation
process, you can use this list as a check list to determine what caused the error.
Set ISO to 100 to reduce noise.
Set the photo mode (style) to standard mode.
Turn off all in-camera correction options.
Use AV mode and set EV to between 0~+1.
Capture RAW images for best results.
Set up the camera on a tripod to avoid burry images. Also, turn off any
vibration enhancement on the lens or camera body.
Avoid shooting in an environment that includes a complicated background.
Ensure the calibration chart is completely in focus for each shot.
Ensure the calibration chart takes up a quarter to a half of the image frame.
Ensure that every square in the calibration chart is displayed in the image.
Note: you can use the Zoom drop down to check if all the calibration chart
squares are displayed in an image once they are imported into the CyberLink
PhotoDirector Lens Profile Generator.
