In art, a value (or tone) is how light or dark a colour is. If you're learning to paint or draw, doing value studies is an excellent place to start. These small, loose sketches in greyscale show where shadows fall and highlights appear. These are particularly useful when the subject is more complicated and it's hard to see through the colours to show the subtle shadows.

If you're learning to paint or draw, value studies are a surefire way to improve both your artwork and how you visualise references in your mind. People often use photo editors to convert a colour photo to black and white... this is helpful, but this app goes further.

By using Value Study, you can flick between levels of detail. Maybe you want to start with just black and white to get a base down, then add in extra values one by one to build up your understanding of the reference you are studying.

You can even take it a step further and select all areas with matching tones. Click one of the values along the bottom in the greyscale palette to see all areas that match it in the image, so you can focus on one value while painting it. For example, in a portrait, this could mean seeing how different parts of the body have the same amount of shadow despite potentially looking wildly different when viewed in colour.

Value Study is a tool, not to replace your value studies but to enhance them and significantly help beginner artists know where to start when looking at complicated reference imagery.

What’s New

Version 2.3.1

This is an exciting release... it's bug fixes, but I have finally figured out how to fix the big one! Yep, ZOOMING should now work properly even when switching selected values and when using the live filter (video) mode. If you're new to this app, this will seem like a tiny thing but I know how many of you have reached out about the bug so I'm glad to release this!

You can also now double tap the image when zoomed in to zoom back out all the way.

Wonderful app and major improvements!!!

I wrote a review last year but I wanted to write another quick one. Once again I’ve used this app for art projects and it has saved my life. Completely!! I don’t have to go through in PS and manually add in the pixelations. Also thank you for confusing to improve every month! Thank you as well for updating the pixelation feature! This will further help a lot for me in my art journey and especially value studying, defining value edges is still very difficult.

Abt the app: Sometimes when I would go in to edit some of my high detailed images it would definitely work, but it wouldn’t be as crisp when the separation was added as I imagined it might be. So want I to thank you for improving that! Once again love this app and I’ll continue to be using it!!! ❤️😉

Developer Response ,

Thank you so much! This is the first review and I’m so grateful that you liked it enough to write it. I was in the same position as you, finding techniques useful but a hassle... I’m really glad the app worked in a way that helped you.

I think you’re right that it would be really useful on iPad as it could work well alongside the drawing apps that people already use. So thanks for the request, will definitely look into it for a future update.

Update: Value Study is now supported on iPad 😀

Update 5th Feb 2022: Thank you so much for your updated review… it means the world to me that you’re still using it and appreciating the updates I’ve made!

In the new settings menu there is a link to send an email, free feel to email with any problems or improvement ideas you have 🙂

Disappointed, but hopeful ,

Fantastic!! Perfect!!

I’m taking an art class and we have to turn in a NOTAN. Quick explanation, a NOTAN is a value study. It would be what you’d see if you squinted and could only see in black and white. Sometimes they are just black and white, sometimes 3-5 values. This app makes this so EASY because you can select any of those shades of grey and tap that value, that value only then turns green on your photo. Once you can see/draw that you can make another value green. In no time a person who doesn’t see values (like me!) can learn to see the difference. My art homework just became possible! Thanks, from someone just starting out in art!!!

Great updates

I am learning to paint and still have trouble distinguishing values. This app is perfect for planning my paintings and checking my progress. I love the new features, especially the ability to adjust the level of detail. I haven’t used the value outline or portrait tools yet, but I think they will be useful as well. I am happy to pay for these upgrades! Also love that the one-time fee includes future updates. Keep up the good work!
