Document Summary
Mitchell"s terminology about photographic techniques and visual truth capture processes and the differences between: analogue photography (physical-chemical process) Lec: interface and fabrication1@february 22, 2021 10:43 am digital image capture (electronic) filtering sampling on grid locations quantization (converting samples of intensity in a finite range process) Pixel = pix (picture) element: fundamental display element of an electronic screen or bitmapped image ex. Monochrome bitmap: simplest pixel representation is a black and white monochrome image in which one bit = one pixel the digital image is the product of process of quantification and filtering = fabrication. Image as "information"" how much can we compress an image to = perceived as low quality compression is an process of fabrication. Pixels as signifiers relations to: creator"s production scnee/thing/phenomenon depicted. Lec: interface and fabrication2 prominent pixels create tensions between process and objects of depiction ex.
