Use Blend Modes to Make Web Apps Stand Out

Blend modes in ArcGIS let you determine how the layers in a map affect each other so you can highlight a specific aspect of the data, produce an interesting effect on a layer, or make what seems like a new layer by blending two or more layers in a map.

However, these Adobe Photoshop-like effects create live, interactive maps rather than static images. Blend modes are available through the ArcGIS API for JavaScript and as an option when authoring maps in the new ArcGIS Online Map Viewer.

This story map illustrates some of the most useful Blend modes: multiply, luminosity, saturation, hue, and compositing.
