How to Fix Low Resolution Photos

By Carol Adams

When using a photo for a purpose such as creating a print ad or posting an image to a Web page, it is generally best to work with digital images that are already large and high resolution. Unfortunately, you may sometimes find that you have no choice but to use a small printed photo for your purpose. However, attempting to simply enlarge a low resolution photo will generally yield a disappointing result. This is because photos are made up of a number of small, colored dots. When you enlarge a photo, you make the dots more visible, resulting in what are known as "jaggies." Fortunately, there are programs you can use that will minimize this problem.

Photoshop

Step 1

Place the photo you want to fix onto your scanner bed and close the top. Open Photoshop, select "File" from the menu and choose "Import." From the options, choose "Select Twain_32 Source " Choose your scanner and click "OK." This will open your scanner software.

Step 2

Set your scanner resolution to at least 300 dpi and click "Scan." The image will be scanned into a new Photoshop document.

Step 3

Select "Image" from the Photoshop menu and choose "Image Size." In the dialog that appears, change the "Interpolation" to "Bicubic Smoother." Increase the width and height of the image to what you need for your purpose. Click "OK" and save your work.
