Step 5.
Finding the optical center |
| To find the optical center of a lens with a focal length of over 70mm you will probably need to set up you camera outdoors. |
|
|
| The picture above show how I have set my camera to align a pole and the edge of a window in the left of my frame. The pole is about 5 feet from my camera and the window is about 30 feet from the camera. The focal length of my lens is 100mm. |
|
|
| The picture above shows what my initial alignment looks like when I then pan to put the pole in the right side of the frame. I will follow the procedure until the pole and window frame remain perfectly aligned just as I did with the nail and line setup. |
|
You will need to follow steps 1-5 for all your cameras and various lenses making note of all final alignment details. |
