## What is Atlas Muse?

Atlas Muse is a reference photo library for artists.

The problem: Your reference photos are scattered across your camera roll, hard to find when you need them while painting.

The solution: Keep references organized in one place. Tag photos so you can filter them instantly. Need hand references? Filter by "hands". Working on fabric? Filter by "fabric".

Tools for painting from reference:

Reference Grid - Overlay a grid to measure proportions and check angles while you paint.

Value Studies - Simplify any photo into 2 to 7 value levels. See the value structure without color distraction.

Notan - Convert photos to pure black and white shapes. Study composition and light/dark patterns.

Black and White - Remove color to focus on values and form.

Color Palettes - Extract colors from reference photos to build your palette.

Built for artists who paint from reference photos. Simple tools that solve real problems.
