The provided context suggests you are asking about how to apply a Levels effect or filter within Adobe Illustrator, potentially to adjust the tonal range of an image or artwork. While Illustrator doesn't have a direct "Levels" adjustment like Photoshop, here's how you can achieve similar results:
There are a couple of ways to make adjustments to the levels using Illustrator:
-
Using Effects (Raster Images): If you're working with a raster image (like a JPEG or PNG) that's placed or embedded in your Illustrator document, you can apply effects to it.
- Select the image.
- Go to Effect > Stylize > Feather (This will simulate a very basic levels effect). Unfortunately, Illustrator does not have a native Levels effect, and this method is a workaround that might not provide exact results.
-
Using Plugins (Advanced): As demonstrated in the referenced YouTube video, you can use plugins to achieve a more precise Levels adjustment. The video comes from "Astute Graphics," a company that creates plugins for Adobe Illustrator. Their plugins provide more advanced image editing capabilities, including tools that mimic Photoshop's Levels adjustment.
- This option requires purchasing and installing a third-party plugin.
Essentially, to manipulate levels like you would in Photoshop (adjusting highlights, shadows, and midtones), you will either be working with a basic filter or will need to use a plugin. Illustrator's core functionality is focused on vector graphics, which don't inherently have the same pixel-based characteristics as raster images, making direct Levels adjustments less common.
