Nobody likes poor picture quality. Even the people who know next to nothing about pixels can see when a photo is pixilated. We will teach you how to resize your photographs without making it pixilated.
With today’s camera’s packing more megapixels and bigger sensors, you’ll more often find yourself scaling a photo down than up. But there are times when enlarging a photo can really come in handy. Unfortunately, increasing the size of a picture usually means a significant loss of quality. There are a few ways you can try to tackle this problem. Below, we’ll go over two best tips on resizing your photographs without making it pixilated.
Important Information Before Resizing
When you increase the size of an image, you’re asking your computer to add information. Put succinctly, you’re telling it to guess at what a larger image would look like. That means you’re never going to get a perfect recreation of your photo at a larger size. Because it’s a matter of software, some apps will be better at it than others. But they all have to make guesses.
The amount of guessing your computer has to do varies with how much you want to increase the size of your image. The more you increase it, the more likely you are to see a degradation of image quality. Understanding that up front is important.
Before jumping into that topic, it is important to know how digital images are formed in the first place. There are basically two different techniques for creating a typical digital image.
- Raster (Bitmap): A Bitmap (Raster) consists of a grid of individual pixels. Each of which is defined by a specific color in the form of binary bits (hence the name). Popular image formats like JPEG, GIF, and PNG save images as bitmap graphics.
- Vector: In vector graphics, a set of mathematical expressions is used to define line segments, curves and other geometrical shapes that combine together to form a complete image.
As vector graphics are mathematical representations, they can be resized or enlarged to any extent without any loss of quality (distortion-free scaling). However once the scaling is done, you can export it to bitmap form in order to use it. Nowadays though, several vector formats, such as SVG, are directly supported in web browsers.
Nearly all photo editing software today provides a few options that enable you to increase the size of a picture. In this article we are going to take a look at how you can enlarge pictures in several different ways, using powerful photo editing software.
Enlarge a Picture with Photoshop
Adobe’s software offers tools that enable their users to perform all image editing actions, which is why it comes as no surprise that Adobe Photoshop is one of the best software you can use to enlarge a photo. Changing the size of a photo is incredibly simple and will not make your photographs pixilated. All you have to do is click on the Image menu, and select the Image Size option. The Image Size window lets you increase or decrease the Pixel Dimensions and Document Size options.
Simply insert the Width and Height values into the boxes to enlarge a photo. Make sure to click on the Constrain Proportions button. This is in order to preserve the aspect ratio of the original image after you change the number of pixels or the size of the document. At the bottom of the Image Size window, you’ll be able to see a drop-down menu that lets you choose between Bicubic, Bilinear or Nearest Neighbor image resizing options.
This method is perhaps the standard way of increasing the size of a photo in Photoshop. However, it isn’t the only one. A plugin like Perfect Resize allows you to have even more control over the image resizing process. It offers features such as Sharpening or Film Grain that produce sharper and more natural enlarged images.
If you decided to install the Perfect Resize plugin in your Photoshop, click on the File menu, and go to the Automate drop-down menu. Find the Perfect Resize option and click on it, so you can launch the plugin.
You can change the size of the document or increase the number of pixels in the photo. Plus, you can remove noise that occurs if you enlarge a photo too much, by using the Sharpening tools. Hit apply when you finish the process of making your photo larger and click on the Save As button to export the photo from the Adobe’s photo editor.
