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.

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.

昔、スリットカメラという特殊なカメラがありました。カメラのフィルム面にスリットが設置されていて、被写体の移動にあわせ、フィルムを回しつづけて、ある瞬間にレンズの前を通りすぎる被写体を連続撮影するという特殊なカメラです。僕の知っている用途は、カメラを回しながらフィルムも送ることで一気に360度パノラマを撮影するか、あるいは競馬や競走の判定に使うか、列車の側面画像を撮影することです。パノラマの場合はカメラの回転速度からフィルムを送る速度も自動的に決まりますが、列車を撮影する場合は、車速に完璧に同期してフィルムを送らないと、列車が伸びたり縮んだりしてしまうので、非常に撮影は難しかっただろうと思います。
現在のデジタルビデオカメラでも、フレームレートが十分速ければ、同じことができますが、1フレームで幅1ピクセルしか撮影できないとなると、十分な解像度を得るには毎秒3000コマぐらいは録画する必要があり、極めて高価なカメラが必要になります。そこで、家庭用のビデオを使い、スリットの幅を広めにとることで毎秒30コマの画像からスリットカメラのような画像を作ってみることにしました。
スリット幅が広くとれると、フレーム同士の位置合わせが容易になり、列車の速度が変動してもほぼ完璧につなぎあわせることができます。フィルムカメラでの最大の困難である、列車との同期が必要なくなります。その他、レンズの補正や露出の補正なども、通常のパノラマ写真の技術がそのまま使えるので、僕のような素人でも上の写真程度のものが簡単にできてしまいます。
これはHuginを使ったテストですが、だいたい技術的課題がわかったので、次は専用のステッチソフトを作って、ビデオからほぼ全自動で列車の画像を作ってみたいと思います。
Height and width of a car is 6 and 20 meters, respectively. When you use the HD camcoder in portrait, it requires about 10 shots (including overlaps) to cover a car. The camcoder records 30 frames per second, that is, 20 meter corresponds to 1/3 seconds. In other words, maximum train speed to be captured is 60m/sec = 216km/h, is enough to capture the Shinkansen! (Of course shutter speed must be fast enough, i.e. you have to take video at very bright place.)
I learnt the technical problem of digital slitscan by this work. Next time I will make original software to stitch video frames into a train shot.

was not one of the results I expected from my first experiments using the Slit-Scan app; but this goes a long way to explaining how the missus talked with me in my office while I was out taking these photos; and how Santa gets his rounds done so quickly. Needless to say this section of the Springwater Corridor is now closed while scientists from around the world study the area; but I'm pretty sure that it's not the local nor the locomotive, but the Slit-Scan app that deserves credit here, a hypothesis I'm confident that further testing will prove correct.

These images were created using a digital slitscan process. I wrote a program that generates several groups of 3d primitives. The separate groups of primitives are rotated in slightly different directions slowly while every frame of rotation a column of pixels is sampled from the middle of the image and used to make a picture.

The film was advanced by 1/8th of a turn after each exposure, so at the beginning, when the take up spool was "slim" the slits overlap, while by the end of the film there is no overlap, or even a small gap.

One of my hacks from Music Hack Day Helsinki, 2013.
"Hackscan - takes a video and summarizes it intelligently into a single image by extracting single columns [or rows] of pixels from each frame. The result is a crazy looking image that captures the essence of the video."

Daily App Experiment #154: "Code" - You know when you are riding in a subway car watching the lights in the tunnel pass by? This is how those lights look when you film them through #SlitScan. I pressed my iPhone against the BART car window, to keep my hand steady, and captured this shot over the span of maybe 20 seconds. No additional effects where used. I wonder what other apps would look cool when filming out a BART window. #Daily_Appsperiment #appsperiment
