Features & Capabilities

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.

I am still mostly a beginner with visual arts. This tool has fascinated me and inspired me. I love doing value studies without color. It’s liberating. I can’t wait to use this app again and again.

Does an incredible job for learning values and includes a variety of tools to adjust values. Worth the price. Would love the addition of a copy and paste option when submitting photos. Besides that it’s perfect.
