Resizing Digital Camera Photos
If you're more familiar with resizing scanned images, you'll find that resizing images from digital cameras is a bit different, primarily because scanners create high-resolution scans (usually 300 ppi or more), but the default setting for most digital cameras usually produces an image that is large in physical dimension, but lower in ppi (usually 72 ppi). The trick is to decrease the physical size of your digital camera image (and increase its resolution) without losing any quality in your photo. Here's the trick:
Open the digital camera image that you want to resize. Press Control-Shift-R to make Elements' rulers visible. Check out the rulers to see the approximate dimensions of your image. As you can see from the rulers in the example here, this photo is around 12×8".
Go under the Image menu, under Resize, and choose Image Size to bring up the Image Size dialog. Under the Document Size section, the Resolution setting is 72 pixels/inch (ppi). A resolution of 72 ppi is considered “low resolution” and is ideal for photos that will only be viewed onscreen (such as Web graphics, slide shows, etc.). This res is too low to get high-quality results from a color inkjet printer, color laser printer, or for use on a printing press.
If we plan to output this photo to any printing device, it's pretty clear that we'll need to increase the resolution to get good results. I wish we could just type in the resolution we'd like it to be in the Resolution field (such as 200 or 300 ppi), but unfortunately, this “resampling” makes our low-res photo appear soft (blurry) and pixelated. That's why we need to turn off the Resample Image checkbox (it's on by default). That way, when we type in the setting that we need in the Resolution field, Elements automatically adjusts the Width and Height fields for the image in the exact same proportion. As your Width and Height decrease (with Resample Image turned off), your Resolution increases. Best of all, there's absolutely no loss of quality. Pretty cool!
Here I've turned off Resample Image, then I typed 150 in the Resolution field (for output to a color inkjet printer—I know, you probably think you need a lot more resolution, but you usually don't). At a resolution of only 150 ppi, I can actually print a photo that is about 6 inches wide by 4 inches high.
Here's the Image Size dialog for my source photo, and this time I've increased the Resolution setting to 212 ppi (for output to a printing press; again, you don't need nearly as much resolution as you'd think). As you can see, the Width and Height fields for my image have changed.
When you click OK, you won't see the image window change at all—it will appear at the exact same size onscreen. But now look at the rulers—you can see that your image's dimensions have changed. Resizing using this technique does three big things: (1) It gets your physical dimensions down to size (the photo now fits on an 8×10" sheet); (2) it increases the resolution enough so you can even output this image on a printing press; and (3) you haven't softened or pixelated the image in any way—the quality remains the same—all because you turned off Resample Image. Note: Do not turn off Resample Image for images that you scan on a scanner—they start as high-res images in the first place. Turning off Resample Image is only for photos taken with a digital camera.
