Part 3. Tips for Upscaling Photos - 8 Important Things You Need to Know

Image enlargement is cumbersome work, often accompanied by reduced picture quality when the size increases. Here are seven crucial pieces of information you must need before scaling up your images for the optimum output.

1. Choose the Highest Quality as Possible

In essence, the quality of the original image bears the brunt of a high-quality upscaling process. One must always start with the highest image resolution you can get. When you try to enlarge a poor or very small image, you will find that the image becomes pixelated or blurry, and the trouble of unpixelate the image can become hard to fix.

2. Right Tool for the Right Job

Not every upscaling tool is made equally. Some are developed for specific kinds of pictures, such as illustrations or anime, for instance, Waifu2x and BigJPG; others, for instance, AVAide Image Upscaler, are the best for amplifying detailed, photorealistic images. Choose a tool that seems to achieve your image format of choice and the quality that you normally prefer.

3. Differentiate AI Tool & Traditional Upscaler

Traditional upscalers employ mathematical algorithms called interpolation to guess missing detail as images are enlarged. In contrast, newer AI upscalers employ more advanced machine learning to do the same with much better results. Other image upscaler tools that sub-utilize machine learning algorithms include AVAide Image Upscaler and Vance AI Image Enhancer, which negate blurriness while preserving sharpness and clearness suitable for intricate images.

4. Check the Image Format & File Type

As with most image processing, the type of file format you begin with will go a long way to defining the outcome when enlarging images. JPEG, for example, is a lossy format. Some data is thrown away to make images small, which often results in pixelated, blurred or even color-banded images when enlarged, especially at large sizes. This is why, although formats like PNG and TIFF are larger than their counterparts, they are considered to be much better for upscaling an image without the application of distortions that are more or less unwanted by the viewer. It is advisable to uncompress a picture before enlarging it because those formats offer more data for the upscaler. Despite the larger size, the quality of lossless files is higher; they are very useful when you print or use high-end devices.

5. Scaling Limits

It is fundamental to understand that each of the upscaling tools comes with its degree of effectiveness. Whenever an image is scaled beyond the maximum recommended size, say more than 8×, it is easily discernible that its quality has dropped. As outlined below, the enlargement ratios should be adhered to to achieve optimal results. For instance, tools such as BigJPG can go up to 16× while offering outstanding results only with certain types of pectoral images such as vector art, animations, etc.

6. Prepare In Making Manual Adjustment

This is a good example that even with the help of AI, upscaling results could be better now and then, there will be errors. You may have to enhance some characteristics of the picture, for instance, enhancement of the focal length or suppression of noise, and many more if the upscaler fails to deliver on these qualities. Applications such as Reshade Image Enlarger offer an option to do the job manually, which enhances the user's control.

7. Over-Sharpening

Scale-up can sometimes lead to very high contrast images, especially where highlights or recessive detail is well defined or sharp edges exist. Removing noise on image options like edge-smoothing provided by Deep Image or Let's Enhance does not make a picture look unnatural and avoids artifacts after upscaling.

8. Consider the Use of the Image

Consider where it will likely be utilized as you make the image upscaled. The quality of the images varies according to how they are to be displayed on traditional websites, newspapers, Facebook, etc. For instance, raw files required for big format prints should be far better quality than those used on the web. Some tools, such as Icons8 Smart Upscaler, are perfect for web-based content extraction, while Pixelmator Pro can be used for detailed print works.
