The web display and print quality differ because of the finite number of pixels in the resolution-dependent bitmap image. Figure 25-1 shows at left a CorelDRAW illustration of a child s paint box. In this book the drawing looks crisp around the edges and smooth in its transitions from neighboring tones. It was a graphic suitable for printing as a bitmap because it was exported at a high resolution 300 dots per inch for printing in this book. However at right is an illustration of the same paint box with the imaginary bitmap grid shown but it was exported at desktop icon size about 48x48 pixels and the loss of image detail is evident at its resolution of 72 pixels per inch. Resolution Pixel Count and Printing It s a frequently asked question whose answer is imprecise what is the resolution I need for a photograph to make a good print Scanning a physical photograph doesn t provide the best sampling of color pixels to produce a terrific photograph but it does ensure that you have a sufficient number of pixels an image s pixel count to print the scanned photo. The most direct way to acquire a photo and manipulate it in PHOTO-PAINT is by using a digital camera. Today s digital cameras are capable of taking full-frame pictures that can be printed to inkjets printers at 12 x18 in high quality. Digital cameras measure the number of pixels in width and height of the picture s frame in megapixels MP a million pixels Pixel color placeholder Low-resolution bitmap FIGURE 25-1 The number of pixels in a bitmap combined with the image s resolution determines whether an image is suitable for printing. CHAPTER 25 An Introduction to PHOTO-PAINT 775 equal a megapixel. For example the Nikon D90 can take MP its sensor array captures 4 288 pixels along one dimension and 2 848 pixels along the other. Thus 4 288x2 848 plus a .
