Whilst a raster image is made up of pixels, which are blocks or circles made up of different colours in order to display an image, a vector is something else entirely. Raster is the term used for images that use pixels and rasterization involves converting a non-pixel image into a digital, pixel-based one. These are stored as ‘bits’ – so the more bpp (bits per pixel), the more colours can be represented. ![]() The more information stored in a pixel, the more colours it can represent. If you have a colour printer, you’re no doubt already somewhat familiar with this when you order new cartridges. Pixels also control colour, made of up of 3 or 4 components known as RGB (Red, Green, Blue) or CMKY (Cyan, Magenta, Yellow, Black). The more pixels an image has, the more you can enlarge it without losing the quality of the image.ĭigital cameras allow you to set the resolution lower and higher and Photoshop allows you to optimise large images for the web without losing quality. In print, this needs to be high to avoid pixilation, but on the web, it’s desirable to have low file sizes so you would want the pixels to be less. For digital imaging, the higher the resolution, the bigger the file size of the image. So, if the resolution of an image is 1280 x 1024 on a computer monitor, then the width would contain 1280 pixels and the height 1024. This is a means of ‘counting’ the number of pixels in an image by width and height. ![]() ![]() Today, images – both still and moving – contain 1000s of pixels in order to give us a more true representation of the subject.Ī pixel is often referred to as the resolution of an image too. He used the language of computers (binary) to scan a photograph into a computer and came up with an image which we would know think of as pixelated.Īs you can see, the quality was poor and this particular image was made up of just 176 pixels. In photography, the first digital image was created by Russel Kirsch in 1957, in order to recreate photographs using a grid system of colours and tones. Essentially, pixel means a picture element and is a contraction of the words picture and element.
