In-Depth Information
The image is at a low resolution of 72 pixels per inch.
This low resolution affects the image quality, and should be increased to print the best image possible.
For this to occur, the dimensions of the image will need to be reduced so the image will be of a higher
resolution, but will be smaller in size.
Resampling changes the amount of image data. When you resample up, you increase the number of
pixels. New pixels are added, based upon the interpolation method you select. While resampling adds
pixels, it can reduce image quality if it is not used carefully.
2 In the Image Size dialog box, uncheck Resample Image. By unchecking the Resample Image check box,
you can increase the resolution without decreasing image quality.
You can use this method when resizing large image files, such as those from digital cameras that tend to
have large dimensions but low resolution.
3 Type 266 in the Resolution field. The size is reduced in the Width and Height text boxes to accommod-
ate the new increased resolution, but the Pixel Dimensions remain the same. For quality printing at the
highest resolution, this image should be printed no larger than approximately 2.09 inches by 1.395
inches. Click OK.
In this image, you are not adding pixels; you are simply reducing the dimensions of the image to create
a higher resolution.
Increase resolution without decreasing quality.
