The Resample dialog box (top) shows that the photo
(bottom) has a resolution of 72 dpi, which is too low for
print.

To increase the image resolution for print, the Maintain
original size check box is enabled first. Next, the
resolution is increased to 300 dpi, and the width and
height of the image are automatically adjusted.

Reducing file size and image
dimensions

If you want to use an image on a Web page,
you need to reduce its file size. You can

accomplish this by resampling, a process that

changes the image resolution. Resampling

(also called downsampling or upsampling)

often causes blurring, but you can counteract

this effect by applying the Unsharp mask

filter (Effects ` Sharpen ` Unsharp mask) to

the resampled image.

Top: The Resample dialog box shows that a photo is

not suitable for Web use. Bottom: To prepare the photo

for the Web, the unit of measure is changed to pixels.

Then, the image resolution is decreased to 72 dpi, which

automatically decreases the width and height of the

image, along with the file size.

The photo that you are preparing for the Web

may require specific width or height in pixels.

You can specify the exact dimensions you need

in the Resample dialog box. When you specify

these settings, the image resolution and the

file size are automatically adjusted.
