Tonal value study
ArtistAssistApp "Tonal values" tab does tonal value study for you.
Tonal values are as important as accurate color mixing. The right values help to create contrast and depth in your paintings.
Tonal value sketches are displayed next to the original image, so it's all on one screen to paint from.
If a painting has a big first wash with just a few highlights it can be a challenge to know where to paint and where to avoid.
But if you have light tones in front of you while painting the first wash it is very useful.
Midtones and shadows can be painted over in the following washes.
You can also print tonal value sketches by pressing the "Print" button.
