Enlarge Pictures With Megapixels
Current digital-camera models have tremendous capability. The top-of-the-range models have the ability to produce large image files, which in turn allows the photographer to make large, high-quality prints based on the native resolution, or number of pixels, in the original file. However, sometimes the native resolution of an image isn't large enough, or the image has been cropped or resized and the number of pixels is too small to produce a print. Using photo-editing software, it is possible to enlarge a photo based on the number of pixels, creating a larger version of the image.
Instructions
1. Determine what type of photo-editing software you have access to. High-end editing software suites, such as Adobe Photoshop, use a complex algorithm to enlarge your photo. This is called reinterpolation, which means that the software will examine the existing pixels and make a decision on enlarge the photo while keeping the same quality. Photoshop offers several options for reinterpolation, since different images may have different requirements.
2. Open your photo in your photo-editing software. This procedure will vary based on what type of software is being used. Open the software, then select the "Open" option and select your photo. This will bring the photo up on your screen.
3. Select the option to resize your image. In many editing suites, this will bring up a dialogue box showing the current number of megapixels and the image size. Enter the desired number of pixels into the box. Be aware that entering numbers may change the dimensions of your photo unless your program offers the option of keeping the current dimensions. If the ratio is not kept, the photo may be distorted. Once the desired number of pixels is entered, confirm your decision and allow the software to enlarge your picture.
4. View the finished result. Enlarging pictures can sometimes lead to a loss of contrast around the edges or blurring. Many programs, such as Photoshop, offer sharpening filters. These tools use another complex algorithm to refine the edges of color areas, presenting a more defined image with sharper contrast.
5. Save the newly enlarged image.
