I took this image in 2016 at the Toronto Indy. This is obviously from a supporting race, not the Indy car race. I shot this, tracking the truck at 1/500th on Provia 100f, but I can’t remember the aperture. There is a small exposure difference between the left and right images due to a sticky shutter on my TL120. This TL120 went to China for a new shutter circuit board (back when you could still do that), but it obviously did not solve my problem. A few shutter cycles between rolls gives me a better chance of matching exposures, which leads me to believe that there is mechanical sticking going on. I would appreciate it if anybody could tell me how to fix this
