Taking pictures with Jokie²
Aligning the camera towards the camera and the
subject
Wherever possible the camera´s focal plane should be par-
allel to the light barrier´s light beam or parallel to the
flight path of the desired subject. This setting increases
the success rate considerably, especially if you are gather-
ing your first experiences with light barriers.
Focal plane parallel to light beam
If the camera´s focal plane is parallel to the light beam,
the subject can be depicted sharply from the left to the
right edge of the image, no matter where it interrupts the
light beam, see image 16.
Moreover, in this context it is irrelevant whether the light
beam is positioned horizontally or vertically.
On the other hand, if the focal plane and the light beam in-
tersect one another in an angle, the subject will only be
depicted sharply when the light beam is interrupted at the
crossing point of focal plane and light beam, see image 17.
