When the jet car "Fire Force" approached the start line the jet blew out. That smoke coming out of the back of the car is pure vapourised jet fuel - slightly dangerous! Luckily it was blown away from the stands. No smoking in the pits please!!!

I have done quite long comment on the theory behind panning and some practical settings to practice with.
Let me know if you have any more specific issues and I will see if I can help.
Thanks for your comments.
