Pixelating an image is when the naked eye can view the individual pixels within an image, and each pixel is made up of the average colour. The word pixel is short for Picture Element, and on monitors such as the TV, there are millions of these which make up the whole image using the colour code RGB (red, green, blue).
Here i created an image using a 140mm x 100mm document, with the colour mode in CMYK which is suitable for printing. This is because RGB has a much wider spectrum of colour which is physically impossible to recreate when printed.
Here is the transformation of a natural photograph into two pixelated images. The smaller pixels are 2cm in size and the larger 6 cm both with 1 subdivision. It is only obvious from the smaller pixelated image what the subject is, i wouldn’t have known from the larger pixelated image which is just a range of browns and purples.
The route of doing this on Photoshop is to select: filter- blur – average, but you must first rasterize the layer which makes it a pixel image.
