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 require this app from my students. Value study is not taught in many art classes. It is difficult to get students to see value in a colorful work of art. This app has given many of my students that “ Ah ha” moment.

Thanks for your thoughtful sharing of this app. I is my “go to” tool when I’m in the design process of creating my paintings. I was easy to learn and now easy to use. I’ve been using this app for years and it is a valuable tool saving me time and often allowing me to understand my work better.
