## Description

Value Study: art reference is a focused tool to help you see value—tone—in reference images more clearly. Rather than simply converting a photo to black and white, it guides you from bold shapes to subtle tonal shifts to improve your understanding of light, shadow, and form.

Starts with black-and-white maps, gradually adds greys, and highlights areas of equal value to reveal tonal relationships. It complements traditional studies for sketching, painting, or digital work. Try it free on sample Unsplash images, then upgrade to Pro with a lifetime or yearly plan to unlock all features across devices.
