FASHION DRAWING- P4:As we can see from the historical fashion drawings earlier in this chapter, what passes for a fashion sketch has adapted and evolved over time, reflecting an aesthetic statement of style that is broadly aligned to the cultural and social values of the day. Since the 1970s, fashion designers have adopted a wide variety of approaches to the fashion sketch. | Technical drawings Vector graphics and bitmaps 1-2 Vector graphic fashion illustrations by Nuttawan Ness Kraikhajornkiti. Digital graphics media first emerged in the 1980s. Desktop scanners and more efficient graphics tablets soon followed enabling designers to digitise hand-drawn artwork for the first time. The development of digital drawing and image-editing software during the late 1980s heralded the arrival of early vector graphics and bitmaps. In simple terms vector graphics are geometric formations such as lines points and curves which are based on mathematical equations to represent a digital image. They produce clear lines that are suitable for drawing flats or specs linear quality is not reduced when scaled up or down in size. Bitmaps are the data structure represented by a grid of pixels that makes up a digital image measured as dots per inch dpi . Pixels are the building blocks of bitmap images such as digital photographs and scanned images. The more pixels an image has per unit the better the quality of the image for colour and resolution. Bitmaps are also known as raster graphics and are stored in various image files such as JPEGs or TIFFs. Since their early application graphics software programs have steadily developed and expanded into a variety of sophisticated user platforms which can be used for enhancing fashion presentations. Technical drawings 90 91 Techniques include digital drawing colouring rendering and image editing for visual formats. Foremost among the available software are Adobe Illustrator and Photoshop which have become industry standards. Photoshop is a graphics editing program that is primarily geared towards photo manipulation. Illustrator is a vector-based drawing program originally developed for the Apple Macintosh in the mid-1980s. Today it has evolved into a sophisticated digital drawing tool that allows for the conversion of bitmap imagery into vector art. Illustrator s versatility makes it well-suited for creating composite
