rally of turkey WRC 206

This isn't a particularly good photograph unfortunately - there are a lot of things that can be improved, small things, but they will make a big difference when you try this again.

The shutter speed is far too slow - you should be aiming to pan at around 1/160 on a straight where cars are going flat out or 1/125 if they are not going quite so fast. The aim is to get the car sharp (which this isn't) with a blurred background. In order to maintain a good shutter speed, use a higher ISO film. (Fuji Superia 400 is a good start)

As a result of the too-slow shutter speed, you have introduced quite a bit of camera shake into the picture wich is extremely distracting and as a result, the car is blurry instead of sharp.

Also, the car isn't quite in focus. If your camera doesn't have AI servo, manually pre-focus on the line the drivers use. In both instances, pick up the car in the viewfinder on the approach and follow it through smoothly as you pan.

The problem with rally photography is that for each car, you only get one chance to get the shot right.
