How to Enlarge a Picture on the Computer
Enlarging a picture is a common way to see more detail in an image or to fit it to a frame. Photography and copy shops charge for this simple task, but it can be done the same way at home even without photo editing experience. With a scanner and graphics software, any picture can be enlarged on a computer in just a few steps and without the cost of taking it to an imaging professional.
Things You'll Need
- Photoshop CS2 or Higher
Place your photo upside down and face down on the scanner and close the lid. Open the software that came with the scanner and hit the preview button. Drag the selection box around the image to select the image to be scanned.
Set scanning options in the software to 600dpi. This setting will allow for a large, high resolution scan. Choose the options for saving the image on your computer and click the button to scan the image.
Open the image in Photoshop via the "File" menu in the upper left corner. Choose the "Open" command and navigate to your image in the browser that pops up. Click your image to select it and click the "Open" button.
Go to the "Image" menu on the top and select "Image Size." Under the "Document Size" heading, set the options in the right side drop down menu to be in inches. Check the "Constrain Proportions" box near the bottom. Enter the dimensions of the intended finished picture in the "Width" and "Height" boxes. Click "Okay" to apply the changes.
Return to the "File" menu. Choose "Save" to make your changes permanent. The scanned image file will now be the desired larger size.
