Looking at the pixel

In Digital Imaging, a pixel(picture element)is the smallest piece of information in an image. Pixels are normally arranged in a regular 2-dimensional grid, and are often represented using dots or squares. Each pixel is a sample of an original image, where more samples typically provide a more accurate representation of the original. The intensity of each pixel is variable; in color systems, each pixel has typically three or four components such as red green or blue, or cyan, magenta, yellow and black.
Above is an example of pixel art, which is defined by the manual editing at a pixel level of the image. I am interested in the pixellation of images in the detail that is omitted and the constructed computerised look and feel it gives to the image.
This painting by Adam Scott distorts the person in the picture by pixellating them. He applies paint pigment in thick coats with vibrant artificial colors, making his images intensely bright to look at. Scott's images are often derived from elements of cinema, old postcards and personal memories and experiences. The pixels may be derived from computer culture and the reliance on technology and the internet that has emerged in our generation.I saw this painting by Kirsten Roberts
Figure, Two Dwarfs and Goat
oil on canvas 122 x 91 cm
at the Oedipus Rex gallery in Auckland in a back room. It immediately stood out for me because of the details it omits that are usually the main focus of the picture- the faces. I love the way they are smeared and distorted.
