Taken with a slit-cam adapted from a simple point and shoot camera. This is a modification of the camera I used last year.

This time it takes standard width frames rather than strips which were several frames wide.
The shutter was wedged open using a piece of plastic tube and some blu-tac, and a 1mm slit, made from black card, was mounted at the film plane. Each time the shutter release is pressed, the motor winds on one frame, in the process moving it past the slit and making the exposure. Each exposure takes somewhat less than a second. The camera, an Olympus Trip 300 (£1.25 from a charity shop), has a slide across lens cover which is ideal to keep light out of the lens between exposures.
Composed from YouTube video. The original image width is 140,000 pixel, which is far larger than the limit of JPEG format.
こういうのにGigaPan技術が適しているんでしょうね。

Virtual slit-scan tests. Shot with the HD video on the Rebel T2i. Each video frame is cropped so only the middle column of pixels remain and then are merged together. The image's horizontal plane is time.
Taken with a slit-cam adapted from a simple point and shoot camera. The shutter was wedged open using a piece of plastic tube and some blu-tac, and a 1mm slit, made from black card, was mounted at the film plane. The cog-wheel which normally engages with the 35mm sprockets was taped over, thus fooling the automated wind on into keeping running for about 4 seconds each time the shutter release is pressed. The camera, an Olympus Trip 300 (£1.25 from a charity shop), has a slide across lens cover which is ideal to keep light out of the lens between exposures. I calculated that with the film moving at 60mm per second (measured by videoing the film winding then counting the perforations) the 1mm slit gives an exposure equivalent to 1/60th of a second. This photo is from the second film in this camera, this time the batteries were newer, and the film advance was faster, so these photos have been compressed horizontally to make them more viewable.

春休みの自由研究は、金山駅界隈を通過する列車の螺旋写真です。金山は8本ぐらい線路が通っているので、列車の通過頻度が高くて良い反面、架線や建物やフェンスなどの障害物が非常に多く、すっきりした背景で撮れないのが難点。

This is a remix of NRK's 10-hour “Nordlandsbanen” minute-by-minute documentary of a train's journey on Norway’s northenmost railway linking Trondheim and Bodø.

The Nordland Railway (‘Nordlandsbanen’ in Norwegian) celebrates its 50th anniversary this year. The railway is 729 kilometers long, and passes thorugh spectacular scenery, varying from the fjord area around Trondheim in the south, through beautiful valleys, over mountains and along fjords before crossing the Arctic Circle at Saltfjellet and descending down to the coastal city of Bodø.
Following the success of the world’s longest live documentary, Hurtigruten minute by minute, the Telemak Canal and Bergensbanen minute by minute, the Norwegian Broadcasting Corporation set out to film the Nordland Railway as well. This time, though, we had to think up a way to show the contrasts one can encounter along the route; the weather, colours and climatic conditions.
The solution was to film the journey once every season, to show the different weather conditions and the great changes in nature’s expression from summer to authumn, and winter to spring.

A frame was taken every 18 or so minutes resulting in 1,920 frames (the same as the width of the original video) and then sliced together.

A video of slit-scan photos. Look out for the blue and yellow signs and the pedestrians.
Each frame is slit-scan photo showing a narrow slice of space across time, instead of a larger space in a single moment of time.
First this short 25fps video is split into its constituent frames.
Then a new image is created by taking a narrow vertical slice from the very left hand side of every frame and placing them next to each other. (In this case the slice is 4 pixels wide, to maintain the total width.)
Then a second image is created by taking the next slice to the right from each frame and lining them up.
This is repeated until the right hand side was reached.
These new individual slit-scan images show both time and space, but are then all animated to create this new video where time and space are in the wrong places, so the tram is going in the same direction, but backwards.

Left is up; down is future. On the left you can see the steam over the surface. The milk-colored “threads” on the left are when, as I began and ended pouring, the stream of milk crossed the pixel row that this was taken from.
Another 1986 shot using the mahogany "slit camera". This time, I turned my head left to right, but moved the shutter from top to bottom.
The lines are from irregular shutter transpor speed caused by the 12-volt cordless drill-driver drive motor, used to drive the shutter across the film plane.
This is a normal 35mm compact camera modified by adding a very thin slit on the focal plane. The camera is operated by rewinding film across the slit as the camera is moved or the object being photographed moves.
The camera I used is a modified Agfa Silette, though almost any camera could be modified in this way.

People and trams and cars and buses and vans passing Senate Square.
The white and green stripes in the background are the white walls and green roofs of the Lutheran cathedral.
Slower things (people) appear wider, faster things (trams, cars, buses) appear narrower. Some people wandered across the square and back, and appear twice.
Made from the central pixel-column of the frames of a four-and-a-half minute video (30 fps, 1920x1080), filmed on my phone in a homemade Lego stand. (Then ditched 1919/1920 of the video.)

Photo taken during baseball game in Amsterdam, N.Y, camera was Nikon EM modified with a razor-thin focal plane exposure. Lens used was Nikkor 50-300 f/4.5 at f/11. Film used was Rite Aid generic 400 print film. I set up my shot from along the third base line, so that the pitcher was throwing to my right. The focal plane exposure was at the start of his pitch, so he had to pass through the focal plane with his entire body to get this exposure. Sprocket holes are left intact to prove that this picture was taken with analogue techniques and was not a digital creation. Photo by Chuck Miller.
The source photographs were taken by Ansgar on the HelsinkiIn blog between February 2012 and January 2013.
