Free Value Analysis Tool for Artists
Reveal darkest shadows and brightest highlights in reference photos with interactive slider. Perfect tool for drawing, shading and value studies. No AI, no watermark, no limits.
When drawing from reference photos, artists need to figure out where the darkest shadows and the brightest highlights are. By mapping out these extreme values, you understand how much shading to apply and where to erase, making sure your drawings are shaded correctly. This makes it easier to create shadows, build artistic contrast, and place highlights accurately, because there is a difference between highlights that we often can’t distinguish properly. This tool makes these differences visible and easy to notice.
Why this tool is perfect for drawing
Artists often ask:
- Where are my deepest shadows?
- How do I know which highlight is the brightest?
- Am I over-shading the midtones?
- Should I darken this area a bit more?
This tool solves these issues, so artists find clear answers to all their questions and doubts while drawing. Use it any time, in any browser, on any device, with no registration required. We don’t see or store your images. This free online tool works directly in your browser. Read our Terms of Use. Have a question or suggestion? Contact us.
Pro-Tip: Use this tool to analyze your scanned drawings as well. Compare them with your reference photo downloaded at the same scale value to see how accurately you shaded and placed the highlights in your image.
