Value Study: art reference

Value Study is a paid art reference tool that helps you learn shading, simplify shapes, and apply Notan concepts. It guides value studies—greyscale sketches that reveal shadows and highlights—while letting you switch between detail levels, from broad tones to finer values. The app also includes free Unsplash images to preview before you buy and offers a low yearly price or a lifetime purchase for full access.

It enhances traditional value studies by letting you select all areas with matching tones, isolating shadows in portraits or scenes. This makes it easier for beginners to visualize references, map tonal relationships, and steadily improve shading skills across drawing and painting without replacing your practice.
