Holst is a project for retouching old paintings. This is definitely not an innovative idea, although painting restoration is a rather standard operation done by well-trained specialists, it is slow, costly, and lacks the level of discretion matched by a modern image editor.
The significant amount of time that has passed from the original creation of many paintings affects their color and brightness. This often makes it difficult to understand what a painting looked like in the moment it was created according to the artist’s vision. Holst’s goal is to use digital technology to repair the defects of age and alter an image’s brightness, contrast, and colors to better reflect the artist’s original creation.
