Value Study Assistant
Simplify Values for Painting
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Value Study Assistant helps painters see the big picture before they begin painting.
Upload any photo and instantly simplify it into clear value masses — from 2 to 10 levels of light and dark. Instead of getting lost in detail, you'll quickly see the essential shapes that create a strong composition.
HOW IT WORKS
1) Upload your photo and choose 2–10 value levels with the slider. Two values gives you a classic notan — the fastest way to check your big shapes.
2) Use the Color / Values comparison slider to flip between your original reference and the simplified study.
3) Tap Modify Values to lighten or darken individual value groups until the structure reads right.
4) Crop your reference to any standard painting proportion — 4:5, 5:7, 11:14 and more — with pinch-to-zoom control.
5) Download your value study as a clean JPG to use beside your easel, on your tablet, or printed in the studio.
Perfect for painters, illustrators, and art students who want to understand the value structure of their reference before committing to canvas.

Ratings & Reviews
Fixes an issue where the Studio Access subscription screen could fail to load pricing, leaving the unlock button unresponsive. The screen now shows clear status while prices load, reports a problem if it cannot reach the App Store, and lets you retry.
Also fixes a case where the request to rate the app was skipped after saving a cropped study.
