Scanography

Scanography (or scanner photography) involves capturing images at high resolutions using a scanner and a computer. The object is placed on the flatbed scanner and a light strip illuminates the object. The light strip passes along the object. While doing so the light reflects the object's image onto a curved mirror then onto another curved mirror and finally into a lens which focuses the image through a filter onto the CCD array. The CCD array processes the image and converts this onto the connected computer. According to the scanning software being used, you can alter the scanner settings for different results.
Before scanning the object you must follow a few simple steps:
- Always clean the scanner first to ensure dust particles aren't distorting the image.
- If you are using a three dimentional object ensure any apparatus, such as a clamp, are sturdy and secure.
- When choosing lighting and backgrounds ensure they compliment your subject.
Scanography has started become very popular with many photographers producing very interesting and innovative photographs using a scanner, as seen below:






Many people disagree with scannography being considered a form of photography due to it not using a camera to capture the image. However, I think it should definitely be considered as a form of photography as it involves different photographic techniques such as exposure and contrast. It also allows for objects to be viewed differently as they have to be placed flat against the scanner. I think it is a great alternative to using a camera and will definitely pose many opportunities for daring photographers in the future.
