As the front suspension moves up and down, the camber angle changes, the castor not. (as per Oily's post)
Peter, In this case I believe that your post and Oily's post are possibly misleading. Later Caterham chassis have anti-dive geometry built into the front suspension. The mountings of the upper wishbone are inclined relative to the lower wishbones. This means that, when viewed from the side, the top balljoint moves towards the rear of the car in bump. Increasing the caster angle.
So, in simple terms a change to the ride height changes the static camber setting, if you have a chassis with anti-dive geometry.
