ValueViewer is an easy-to-use tool for artists who paint from life. Whether "en plein air" or in the studio, ValueViewer will allow the user to take a photo of their subject, view it in grayscale, or posterize it into two or three values. You may also select an existing image directly from a photo album on your iPhone or iPad.
Controls let you adjust the light, mid-tone, and dark area of your image to "key" your painting correctly, and assist in helping you "see" value, even in the most unforgiving light. The image can be zoomed in and out, scrolled, and rotated into position to help you find just the right composition for your painting. Convenient adjustable 'frame' overlays help you crop the image to fit your canvas, and grids can be displayed to help you to compose your painting or transfer the image to your canvas.
Experience artists consider the ValueViewer an "indespensible" tool, and even use it check the integrity of their composition and color choices as they work on a painting.
Thousands of amateur and professional artists rely on the ValueViewer everyday.

A must-have app for every artist
I heard about this app from reading Jo Mackenzie’s book Three-Step Watercolors. I had been looking for an app that would help me view the NOTAN patterns in my photo references before I started a new art piece.
After getting tired of squinting all the time to look at my photo reference to discern the NOTAN patterns, I was grateful to discover the existence of this app.
I like that I am able to get both the gray-scale and the NOTAN views of any of the photos I have in either my iPhone or the iPad. The app works best for my aging eyes in the iPad because of its larger screen.
Excellent value finder for sketchbook artists
I use this app all of the time. I can zero in on the three or four values easily. And I can start off with my black brush pen for the darks and fill in with Watercolors. I think with some on-site sketching I will be more confident in getting the values and shapes correct. I highly recommend this tool.
I liked this until it started freezing up on me. Especially in the GR mode. It locks up my screen and so basically I can't go any further. I have tried squeezing the frame, moving it up and down, taking a photo of the screen....nothing....I sure wish it would work because it's great otherwise. I needed the GR mode to share with my students regarding dividing up the composition to get the best design. Can you help? Thanks so much.
