Defining file types One of the most confusing things about working with paint objects is the great variety of file types. The most common image file types are GIF, JPEG, TIFF, PICT, and BMP, as well as EPS (which can con- tain both paint and vector objects). GIF and JPEG:  Compressed formats that are used heavily on the Internet. The compression levels allow these images to achieve small file sizes and as a result they download quickly over the Inter- net. However, file size compression comes at the expense of image and color integrity. TIFF, PICT, BMP and EPS:  These files have a lower level or no amount of compression. Information for every pixel is recorded, and this can result in large files. Because of the higher resolution and detail needed for printing, these formats are often used for projects that will eventually be printed commercially. There are a number of ways in Canvas to place an image file in your document. In addition to the Place command in the File menu, there is also the Acquire command in the Image menu. Finally, you can directly scan into Canvas using any TWAIN com- patible scanner, or a scanner with a Photoshop™ compatible acquire module. Creating a duotone vignette In this lesson, you’ll learn how to create a duotone and make a vignette from a photograph. A duotone is a grayscale image usually printed with black and an additional color. A vignette is a non-rectan- gular image, usually with a soft edge. You will also crop the photograph, change the image mode, and apply a vector mask to complete the vignette effect. To begin, open the file named “Image1.cnv” in the Tutorial folder.
