Self portrait from my series "Muethers heritage" discovering the remains of famous gdr architect Ulrich Müther. This one was rather scary since only the sceleton of the building was still standing and one wrong move would have been fatal.
most of the times I will use an intervalometer to trigger the shots. If it is too dangerous to focus on timing and riding at the same time, I sometimes will bring an assistant to push the trigger, after I set everything up.
@Airik: what intervalometer do you use? I have setup my D750 at 1fps and tried shots like this, which worked, but I would love to have something that shot faster.
@schilly: just some noname brand with Canon mount. Really nothing special. Every one of those should be able to trigger a short burst if you set if of right.
