In times gone by, films were taken of races from various elevated positions around the track. Long shots were taken down the front and/or back stretches. These were imaged on film in small canisters and after the field had passed these positions, a car with a driver and catcher would proceed inside the outer rail, stop under the position and the camera operator would drop the canister to the catcher...who often used a baseball glove to make the catch. The canisters would then be brought to the stewards for review in case of any challenge. The camera used for photo-finishes was permenantly mounted at the finish line
