Painter Values Check is a free iPhone app developed by Daniel Lao that allows artists and designers to check the values of their paintings in realtime. Values, which refer to the relative lightness or darkness of colors, are essential for creating contrast, variety, and focal points in a painting.

With Painter Values Check, you can use your device's camera to capture an image or import one from your Photo Gallery. The app then generates three versions of the original image: the values version and two simplified values images. This allows you to easily check if your painting or image is working effectively.

One of the key features of Painter Values Check is its ability to calculate the histogram of every captured frame and organize the values into categories such as "Dark," "Middle dark," "Middle light," and "Light." This helps artists and designers analyze the variations in their paintings, drawings, or pictures.

To use the app, you will need to grant camera permission for it to work properly. Once you have captured or imported an image, you can export any of the resulting images for further analysis or sharing.

Painter Values Check is a valuable tool for artists and designers who want to ensure that their paintings have the desired visual impact. With its realtime value analysis and easy-to-use interface, this app is a must-have for anyone looking to improve their artwork.
