To change the pixel dimensions of an image (Photoshop):

1 Choose Image > Image Size.

2 Make sure that Resample Image is selected, and choose an interpolation method. (See "Choosing an interpolation method" on page 66.)

3 To maintain the current proportions of pixel width to pixel height, select Constrain Proportions. This option automatically updates the width as you change the height, and vice versa.

4 Under Pixel Dimensions, enter values for Width and Height. To enter values as percentages of the current dimensions, choose Percent as the unit of measurement.

The new file size for the image appears at the top of the Image Size dialog box, with the old file size in parentheses.

9 For best results in producing a smaller image, downsample and apply the Unsharp Mask filter. To produce a larger image, rescan the image at a higher resolution.
