I went to the recent Phillip Island historics but used a electronic light collection device. Seeing the 917 on track was a thrill even if he (Jim Richards) was cruising.
At PI, with 300mm you can get close enough in most spots (some need a lot less), a few need 600mm to get close enough. The last time I went (2 years ago) I did take some B&W. None scanned to give an example. I think some differences in those pics and 'old' ones are the camera angles (in the old days they stood on the apex of the corner a lot of the times) and the trackside scenery looks 'modern'. Things like curbs, fencing and buildings.
