Image Processing Reference
Image Size is used after the con-
version to resize an image file for
a specific use.
To access this dialog, choose Image > Resize > Image Size (Photoshop Elements)
or Image > Image Size (Photoshop).
For printing, enter the Width or Height in the Document Size fields for the final
print. For web or screen use, enter a Width or Height in the Pixel Dimensions fields.
Note: If you leave Constrain Proportions checked—and I recommend that you do to avoid distorting the
image—set the important dimension, either width or height. The other dimension will be set automatically.
Resample Image offers several options. For photographic images, there are only
three options that will give good results.
Bicubic is the standard method and does a good job for most images.
Bicubic Smoother is the best choice when enlarging images and will do the best
job of interpolation when adding pixels to create a larger image.
Bicubic Sharper is a good choice when reducing image size. This option can
oversharpen a image, though, so if the resized photo appears too sharp, use stan-
Back in Chapter 3, I discussed sharpening in Camera Raw and I recommended that you
wait until all image edits and resizing were done before applying any sharpening to
your converted RAW files.
Photoshop Elements and Photoshop offer several options to sharpen images, all
of which are found under Filters > Sharpen. The chief one that I recommend using,
though, is Unsharp Mask. This filter gives you complete control over how your images
are sharpened and can be adjusted for different needs.
Note: For more detailed information on sharpening images, I recommend Photoshop Sharpening, an
e-book by Tim Grey. It's available at www.sybex.com .
