If you're looking to improve the quality of images within InDesign, the best thing to do is to make sure you’re using the best quality images available. This means using images with a high resolution. Also, be sure to avoid resizing images too much as this can also affect their quality.
InDesign also has a few features that can help you further improve image quality. First, there is the Effects panel where you’ll find optimization and resampling options. For example, you can try doing a low-pass filter on your images to reduce noise and spurious details from them. You can also uncheck the “Resample Image” checkbox if you want to reduce image resampling.
Another useful feature to enhance image quality is the Adjust Image panel. This is found under the Effects menu. It gives you the ability to apply adjustments to your images such as adjusting the brightness, contrast or sharpness. It also lets you control levels and curves to fine tune your images.
Finally, InDesign also offers a range of ways to optimize your images for output. These include options such as JPEG compression and downsampling.
By following these steps and using the right tools, you can improve image quality in InDesign and ensure your images look their best.
