slit_scanner_darkly

Slit scanning. From frames to weird final product.

This is a repository that allows for creating several types of slitscans (examples available further down the page).

Setup:

0. Install ffmpeg and Python 3
1. clone this repo
2. cd slit_scanner_darkly
3. mkdir venv
4. python3 -m venv venv/
5. source venv/bin/activate
6. pip install -r requirements.txt

Single Slitscans: Single slitscans come in two flavors: horizontal and vertical. This style of slitscan is inspired by Adam Magyar's Urban Flow project.

Moving Slitscans: Like the single slitscans (horizontal and vertical), but compiled over all the images in a sequence. Each new frame is a single slitscan from a different x or y coordinate.

Github doesn't let me embed YouTube vids... lame. I put a few gifs in, but for full examples see the videos.
