    #sliding slit between the subject and the photographic plane   
    The Pioneers of photography in the 1800s were apt to try all sorts of experimental techniques including a technique called slit scan. Slit scan is the process of putting a sliding slit between the subject and the photographic plane. The photographic medium under the slit would be exposed as the slit traveled from one side of the frame to the other.

    #earliest uses was for panorama photography    #Ellipsen Daguerreotype    #Megaskop camera   
    One of the earliest uses was for panorama photography. Originally developed by Joseph Puchberger in Austria of 1843. The Ellipsen Daguerreotype, was a swinging lens system to capture 150 degree views onto 19-24 inch long plates - keep in mind this is the era before flexible cellulose film. The following year in 1844, Friedrich von Martens, a German living in Paris, made the Megaskop camera a similar device using a swinging lens but controlled by gears and handles.

    #important use was at the Race track   
    Slitscan had other uses as well - one really really important use was at the Race track.

    #Strip photography   
    Gambling on races had become very popular in the 1940s and avoid the air of corruption in tight finishes, race tracks needed a photograph of who came in first. Contrary to what movies or cartoons depict, these photo finishes weren't just some guy with a flash bulb at the finish line and a hair trigger. Instead they used a variation of the slit scan called Strip photography.

    #To the Moon and Beyond   
    Well in 1964 a short film titled "To the Moon and Beyond" premiered at the World's Fair in New York City. In was shot in Cinerama 360 which was a 70mm single film process using fisheye lenses and projected onto a domed screen. In attendance was Stanley Kubrick who was getting ready to shoot his grand space opus. Kubrick hired the special effects company behind "To The Moon and Beyond" to create some preliminary test shots for the 2001.

    #1958 film Vertigo    #first film to use a computer for animation    #World War 2 artillery targeting computer   
    For the Stargate Sequence Trumbell was inspired by the work of Animator John Whitney who also worked on "To the Moon and Beyond". John Whitney was the animator that worked with Saul Bass on the spiral graphics for Alfred Hitchcock's 1958 film Vertigo - which happens to be the first film to use a computer for animation (the computer happened to be a World War 2 artillery targeting computer). During the 1960s Whitney had been experimenting with leaving a film camera shutter open for long durations while moving artwork on motorized tables.

    #Recreating the Stargate with Lego   
    Recreating the Stargate with Lego After looking Douglas Trumbell's schematic for his Slitscan device, I decided that making a modern day scaled down model wasn't totally out of reach - Although I may have underestimated how difficult it would be.

    #mechanized slider   
    Like most mad scientist-slash-filmmakers, I had a mechanized slider lying around. I built this a couple years ago by adding a timing belt and pulleys to a slider with the intent of being able to automate the movement.

    #Lego Technic gears and bricks   
    Built out of Lego Technic gears and bricks which I had since I was a kid, this gizmo draws power from slider's timing belt, sends it through some bevel gears and a chain where it turns a worm gear. This worm gear slowly rotates a large gear on which the artwork carriage sits. The artwork itself is transparencies with various patterns printed on by an inkjet printer.

    There's nothing quite as humbling as spending a 12 hour day creating 16 seconds of footage.
