How to Increase the Resolution in Photoshop

Increase the resolution of your photos using Photoshop.

With the advent of digital cameras, it became possible to take high-resolution digital photos and store them for later editing. However, there are times when you are forced to use a small, low-resolution print image for a project. You'll want to increase the resolution of the image, but doing this the wrong way can result in a fuzzy, grainy image. Using Adobe Photoshop can help to reduce this effect.

Things You'll Need

• Computer

Instructions

1. Load the image that you want to work with onto your computer. If it is already in digital format, transfer it from your phone or other equipment to your computer. Otherwise, scan it in.

2. Open Photoshop. Select "File" from the menu and choose "Open." In the dialog that appears, locate the file you loaded and open it.

3. Select "Image" from the menu at the top and choose "Image Size." A new dialog will appear.

4. Go to the bottom of the dialog and change the "Interpolation" method from "Bicubic" to "Bicubic Smoother." Then double the pixel width and height of the image. Click "OK."

5. Go to the bottom of the dialog and change the "Interpolation" method from "Bicubic" to "Bicubic Sharper." Increase the resolution by 50 percent and reduce the size back to the original amount. Click "OK."

6. Repeat steps 4 and 5 until the resolution is what you want. Save your work.,
