On Sunday, I visited Cadwell Park with Phil for the Historic Racing Cars event. Brought back many memories of going to Brands hatch in the 1950s opnwards as a child. The weather was perfect for walking round the wooded and very attractive site though a bit bright and contrasty for photographing shiny cars! or for really slow panning. I varied the panning rate and found that the very small and very fast SuperKarts gave a real challenge (1/400th). For the comparatively slow Formula Ford cars it was around 1/320th and for the Sports Cars etc right down to 1/125th. Obviously head-on shots required 1/2000th and above
