This article or section needs to be updated to include current information regarding the subject because:
This page (and wiki) has the terms "albedo" and "diffuse map" inversed….
Remember to check for any notes left by the tagger at this article's talk page.

An albedo, often interchangeably referred to as diffuse map, is a term used to describe reflection coefficient of a material surface containing view-independent Base Color information without any additional lighting or shadow information. Often stored into a Image Texture.
It's used to tell which color tint and initially add basic details for a Diffuse surface. And defines what we normally think of a texture as being before enhanced by other "treatment" textures like bump maps or specular masks.

Engine

Engine-wise, Albedo is usually used to archive a brighter or toon-like surfaces, such what we see in Dota 2 Dota 2 and Team Fortress 2 Team Fortress 2 characters. Often confused and interchange term for Lambert Diffuse texture, often combined with other informations such radiosity maps, luminance maps, shadow maps, diffuse maps and occlusion maps as cheap shading aproximation.
