iStitches Volume Five 对比 ValuePal 的使用情况和统计数据

Every color has an underlying value between pure white and pure black. Being able to translate a color into its value is surprisingly difficult, but essential for bringing your paintings to life. ValuePal is the only gray scale value finder that will instantly give you the grey scale value of any part of an image with just a touch. You can then compare your value to a reference image by swiping back and forth. An advanced feature of ValuePal allows you to create a “value map” of all areas having the same value. This helps you see a pattern for that value(s). Another feature, “bracketing”, can be used to establish the fundamental structure of your painting. It is useful in visualising paths of light and dark in your painting. The ’Notan’ feature converts all shapes to black and white. This helps the artist identify light and dark patterns in their work. No other app has more features to make you a better painter! ValuePal is the essential artist tool!
