We get a lot of requests to convert photos to vector format. One of the reasons is that some printer's guidelines state that in order to print good quality images in large format vector graphics are required. Maybe a little clarification is needed because vector graphics are drawings, so converting a photo to vector means making a drawing of the photo and that isn't necessarily what is needed or wanted. Most printers will accept vector AND high resolution; in this case, designs including photos can then be provided to printer using both vectors plus non-vector good quality photos. If the images you want printed in large format are: A. Photos Images that are captured with a camera need to be supplied in high resolution (large image*) format. Photos are not scalable so simply enlarging a small image will result in a poor quality large image. The photo must have been taken with a high quality setting on the camera, so that it will be the size needed for t...
There are two main type of image files: Raster and Vector. Raster images are created with pixel-based programs or captured with a camera or scanner. They are more common in general such as jpg, gif, png, and are widely used on the web. Vector graphics are created with vector software and are common for images that will be applied onto a physical product. Also used in CAD, engineering, and 3D graphics. When using a raster program you paint an image and it's similar to dipping a brush in paint and painting. You can blend colors to soften the transition from one color to another. When using a vector program you draw the outline of shapes: and it's similar to creating an image with tiles of all different shapes and sizes. e.g. an eye shape, a nose shape, a lip shape. These shapes called objects display one single color each. A lot of images can be made with either raster or vector program and look exactly the same on both programs. Images with a subtle gradation of one col...
