Configuring your Camera
Changing the Strength
You can change the strength of a lens in the user list two ways:
• Reset the lens to factory defaults (see
page 5-42
). (This feature is
available only for lenses that were in the master list.)
• Determine the optimum strengths using Photo Desk, (see
page 5-40
),
then assign the strengths to the camera (see
page 5-41
).
Determining the Optimum
Strength
Do the following when you are changing the strengths of a lens in the user
list or when you are using the Manual method (see
page 5-28
):
1. Capture an image of a gray card at normal exposure. (Fill the frame
with the gray card.)
2. On your computer, open the image in Photo Desk.
If the lens optimization strength is too low, the corners of the image
appear green or yellow.
If the lens optimization strength is too high, the corners of the image
appear blue or magenta.
3. In Photo Desk, use Click Balance at the center of the image.
4. Click Lens Optimization, then adjust the slider to make the corners
neutral. The number for the appropriate strength appears. Click OK.
5. Make a note of this number so you can assign it to the lens
(see
page 5-41
).
6. Repeat steps 1 - 5 for all combinations of minimum/maximum focal
length, and minimum/maximum aperture.
NOTE: Refer to the Help for Photo Desk for more information.
