Spectators lean left while the speeding car tilts right all because of some facts about how his camera works. Lartigue’s camera had a focal plane shutter, a two-part light curtain that slides to one side to expose the film while the second part follows a moment behind to again block the light. While slow exposures might allow one curtain to open fully before the second closes, fast exposures require both to be in motion at once, often exposing only a tiny slit of the film at any moment while they travel across the frame. The result is that each bit of film represents a slightly different moment in time. In the picture above, the curtains moved from bottom to top. The race car tilts to the right because the car itself moved quite quickly compared to the curtains.

The spectators lean to the right because Lartigue was panning the camera from left to right to follow the race (though he clearly wasn’t panning fast enough to keep the car in the center of the frame throughout the exposure). RIT’s Andrew Davidhazy appears to be quite a fan this distortion, which is often called “slit-scan photography” when used creatively. Wood Floors Beyond RepairThe shutter curtains on new cameras often move too fast to reveal much distortion, so he built an add-on that would help him get the slit-scan effect.T Shirt Kale Besides being fast, most modern film cameras shutter curtains now travel horizontally, rather than vertically. Used Furniture Stores Quebec CityThis changed orientation limits our ability to see any distortion, as most fast motion is also horizontal (the effect on Lartigue’s car would have been everything getting slightly wider or narrower).

What amuses me, however, is that digital cameras are bringing this type of distortion back. A digital camera’s imaging element, either a CCD or CMOS sensor, is made up of pixels that are organized into horizontal lines that are then stacked to make a picture. And the camera takes the picture by reading each pixel from left to right, line by line, from top top bottom. In the end, pixel number one in the upper left corner of the frame is sampled long before pixel five million in the lower right. Sure, the whole process is usually done fast, very fast, but it’s not fast enough to keep these helicopter rotor blades from looking bent. The camera in my Clie has a particularly slow scan rate, making it easy to lean cars sideways. I took advantage of the effect for a self portrait when I wanted to blur my office in the background.How to use a shower curtain to rip ice off your carFor the use of the term in motor racing, see Touring car racing. 1913 Maxwell Model 24-4 touring car

A touring car is an open car seating four or more. A popular car body style in the early twentieth century, it declined in popularity in the 1920s when closed bodies became less expensive. A tourer, in Britain and the Commonwealth, is a similar vehicle; however, the term is sometimes used to describe pre-war two-seaters which, in US terminology, would be roadsters. The term "all-weather tourer" was used to describe open vehicles that could be fully enclosed. A popular version of the touring car style was the torpedo, with the hood/bonnet line at the car's waistline giving the car a straight line from front to back. This eventually became the normal version of the touring car, and the term "torpedo" fell out of use, having been replaced by the hardtop. 1920 Studebaker Big Six touring car with its top down. The folded top behind passengers was known as the "fan" when in the down position. In 1916, the US-based Society of Automobile Engineers defined a touring car as: "an open car seating four or more with direct entrance to tonneau."

[1] The term has also been defined as an open car seating five or more.[2] Touring cars may have two or four doors. Engines on early models were either in the front, or in a mid-body position. Side curtains, when available for a particular model, could be installed to protect passengers from wind and weather by snapping or zipping them into place; otherwise, drivers and passengers braved the elements. When the top was folded down, it formed a bulky mass known as the "fan" behind the back seat: "fan covers" were made to protect the top and its wooden ribs while in the down position. 1924 Ford Model T touring car The touring car style was popular in the early 20th century, being a larger alternative to the runabout and the roadster. By the mid-teens in the United States, the touring car body had evolved into a variety of types, with the four-door touring car, equipped with a convertible top, being the most popular body style offered. Most of Model T's produced by Ford between 1908 and 1927 were four and then three-door models (with drivers sliding behind the wheel from passenger seat) touring cars, accounting for 6,519,643 cars sold out of the 15,000,000 estimated Model T's built.

In terms of percentage, the 5-passenger touring car model was Ford's most popular body type and accounted for 44% of all Model T's (cars, trucks and chassis) sold over the model's eighteen-plus year life span; Ford's second most popular body style during the same period was its Model T based truck. The popularity of the touring car began to wane in the 1920s when cars with enclosed passenger compartments became more affordable, and began to consistently out-sell the open cars. An Australian built 1948 Ford Anglia A54A Tourer with hood down and side curtains attached. The belt line in the front door is lowered. The British tourer, as an open car with minimal weather protection, is similar to the touring car, and the terms have been considered interchangeable;[5] However, not all definitions specify tourers to have four or more seats,[4][6] "All-weather tourer" was used for open four-door cars with high quality tops and winding windows;[4] these vehicles were later called convertibles.

In Australia tourers may have two or four doors. The belt lines of tourers were often lowered in the front doors to give the car a more sporting character.[6] and would then be named sports tourers. 1927 Austin 20 with tourer body—a typical example this car is not an all-weather tourer See also: Morgan Four Seater Main article: Torpedo (car) 1914 Humber 11 torpedo. The straight line from the radiator to the back of the car makes this an example of a torpedo body The torpedo body style was a type of touring body used from the early twentieth century until the mid-1920s. A torpedo's hood (bonnet) line was level with the car's waistline, giving a straight line from front to back. The torpedo body style was usually fitted to 4 or 5 seat cars and was a touring car with detachable or folding top (hood) and low side panels and doors, but no B pillars: the only uprights present were those supporting the windshield (windscreen). The torpedo style became the normal style of touring car and the name fell into disuse around 1920.
