![]() ![]() Common vector formats include AI, EPS, SVG, and less frequently PDF. In addition, since vector files aren’t composed of millions of tiny pixels, they tend to be considerably smaller than raster files. The primary advantage of vector images is that they are perfectly scalable without a loss of quality. Vector images/graphics are based on mathematical formulas that define geometric shapes such as polygons, lines, curves, circles, and rectangles. Common raster image formats include JPEG, PNG, TIFF, GIF, and BMP. If you zoom in on a raster image or print a lower-resolution JPEG, you’ll be able to see the dots of color, also referred to as a pixelated image. Raster images/graphics are bitmaps of images consisting of a grid of individual squares (pixels) coded to a specific color hue or shade that combine together to create the image. Compression, file size, and speed of transmission are factors you need to consider. A few things need to be kept in mind in order to select the best image type for specific uses (e.g. ![]() Just like negatives, slides, and prints, not all digital image types are created equal. The good news is that unless you’re a graphic designer, professional photographer, or work in a related field, you probably don’t have to worry about any file types beyond the most common ones. If you took photos with a film camera, you may have been familiar with some basic terminology, although the image files themselves were simply referred to as negatives, slides, or prints.ĭigital photography is much easier in virtually every way, however, the one aspect that is a little more complicated is the vast number of image file formats. ![]()
