Here’s a simple and quick guide on how to change opacity of an image in Adobe InDesign:
- To change the opacity of an image, select the image to access its Appearance or Effects settings.
- In the Appearance section, click 'Opacity' to open the Opacity panel.
- Once the panel opens, under the Opacity box, type a value or adjust the slider to set how transparent or solid you want the image to be.
- As you adjust, you’ll see the image update in real time, indicating the opacity is being applied.
