第 2 部分。 如何在 Photoshop 中修复质量不佳的图片

提高你的形象质量并不难。但是，由于其界面和功能，使用 Photoshop 来升级您的图像可能非常具有挑战性。但不要担心，因为我们将教您如何使用 Adobe Photoshop 来提高图像质量。

Adobe Photoshop is excellent in photo editing and photo manipulation. This editing software is being used by many professional editors worldwide. In addition, it has many advanced editing tools you can use to edit your image. Also, Adobe Photoshop is downloadable on all cross-media platforms, including Windows, Mac, and Linux. Moreover, you can edit banners, logos, brochures, and more using this editing app. And what many users do not know is that it can also improve your image quality. Although you must purchase it before downloading it, Adobe Photoshop is worth your money.

如何在 Photoshop 中修复低质量图片：

在本教程中，我们将通过放大图像以查看其分辨率来提高图像的质量。

Step 1. Download Adobe Photoshop on your computer. Follow the installation process, then run the app on your computer.

Step 2. Open your low-resolution image on Adobe Photoshop. Here is a sample image that is zoomed in at 100%. As you can see, the image has a low resolution.

Step 3. And then, go to Image > Image Size. Then, change the type of anti-aliasing to enlarge and smooth your image on the Resample Image. Change it to Bicubic Smoother, which is best for enlargement.

Step 4. You can see the difference between the two images below when changing it to the Bicubic Smoother version. Altering the anti-aliasing makes a huge difference in the smoothness of your image.

Step 5. Now, we will improve the enlarged image by changing its details. Most Photoshop users do not go beyond RGB and CMYK. And today, we will be using a different color mode, Lab Color. Go to Image > Mode > Lab Color.

Step 6. Next, make sure you open a panel by going to Windows > Channels > Lightness channel. You can also click the hide layer icon beside the a and b channels.

Step 7. When selecting the Lightness channel, go to Filter > Smart Sharpen > Sharpen to add the Smart Sharpen filter.

Step 8. And then, you can adjust the settings of your photo and find your desired output. Always remember that you need to keep the Remove settings to Gaussian Blur.

Step 9. You can choose to maintain your picture in Lab Color or revert it to RGB. And that’s it! Here is the result of your image. You will notice that the image quality is improved and has a richer texture.

瞧！按照上面关于如何在 Photoshop 中修复劣质图片的指南，您可以提高图像质量。
