This track day, I got a ride from my friend Tommy, I was able to use the full day to walk around the track and shoot at many different turns. Actually, the only turn I couldn't get to was turn 1. There are some very good places to take photos, but there's a gate with locks. Later I found out from track staff that it's the organizer that can grant access.
The four pictures below are my favorite from this shoot, you can find the other selected photos here.
