- Change the printing size of the image by typing a number in the Width,
Height, or Resolution (pixels per inch) field. A change to any one of these
fields will update the values in the other fields. For example, if the current
print width is 15 inches and you want a 10-inch-wide print, type 10 in the
Width field.
The Resolution value is helpful, as it tells you how many pixels per inch will appear
in the print, so you can estimate how sharp it will look. Most color inkjet printers are
very happy printing images at 150–300 pixels per inch (ppi). If you enter a number
in this range in the Resolution box, the image will print well on the printer.
The following section continues with this exercise after explaining the purpose of
resampling.Resampling an Image
Sometimes you must change the number of pixels in an image by resampling. This
often happens when you need to reduce (downsample) a large image for a Web site,
or enlarge (upsample) a low-res image for a large-format printer. For these situations,
you must resample the image.
An image that begins its life as a print 2,400×1,600 pixels in resolution must be
made much smaller to be viewed on the Web, anywhere from 90×60 to 800×600.
Resampling downis usually not a problem if there is more information than you
need (see Figure 9.6). Let Elements use fancy math to remove this data properly.118 ABSOLUTE BEGINNER’S GUIDE TODIGITAL PHOTOGRAPHY
