For those who don’t already know the concept, here there are two links explaining what slit-scan photography consists in: Wikipedia, PetaPixel
CONSIDERATION
If we understand a photography as a representation of the space (where we are capable to perceive 4 dimensions: 3 spatial ones, that can be represented in a Cartesian coordinate system with the X, Y and Z coordinates, and one forth temporal dimension). In traditional photography, the temporal dimension is blocked by choosing the moment when we press the camera shooter and one of the three spatial dimensions is also blocked as we choose a projection of the space by deciding the perspective. For this reason, the resulting photography can be represented in a 2 dimension plane: the camera film and later a photographic paper.
We can say that a common photography is representing the X and Y coordinates of the space and fixing the time and 3rd space coordinate (despite actually a photography is a 2D projection of the 3D spatial coordinates rather than a slice of the space volume).
Slit-scan photography allows us to substitute one of the space coordinates translated to the photography by the time dimension. Thus representing the time instead of the X spatial coordinate. In other words, you are recording the visual information of what you can see through a slot (with theoretically a differential thickness) with the pass of the time. This allows capturing the time in the image (by sacrificing one spatial dimension).
It can be interesting to apply this technique to represent the evolution of things through time. Especially when the motive is dynamic and its shape evolves with the time. My personal interest in photography is basically the sea and the waves (Flickr), for this reason, I have used this technique to represent the dynamism and shape transformation of sea waves from a different and interesting point of view.
We #celebratephotography here at Adafruit every Saturday. From photographers of all levels to projects you have made or those that inspire you to make, we’re on it! Got a tip? Well, send it in!
If you’re interested in making your own project and need some gear, we’ve got you covered. Be sure to check out our Raspberry Pi accessories and our DIY cameras.
Adafruit publishes a wide range of writing and video content, including interviews and reporting on the maker market and the wider technology world. Our standards page is intended as a guide to best practices that Adafruit uses, as well as an outline of the ethical standards Adafruit aspires to. While Adafruit is not an independent journalistic institution, Adafruit strives to be a fair, informative, and positive voice within the community – check it out here: adafruit.com/editorialstandards
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
Have an amazing project to share? The Electronics Show and Tell is every Wednesday at 7pm ET! To join, head over to YouTube and check out the show’s live chat – we’ll post the link there.
