The relationship between image and impact
Impact is the force used to depress metal with the diamond tip. Click the “Details” of the Material to change the values. The darkest point of the image is reproduced according to the value of MIN impact. The whitest point of the image is reproduced according to the value of MAX impact. As the value of the impact increases, the entire image will be whiter. As the value of gamma is changed, METAZA marks much darker (or much lighter) parts of the image with the same impact. You can see the relationship between impact and the shading of the image in the following graph.
Graph Explanation
MAX impact
The line in gamma = 1
Gamma = 0.5 (default)
MIN impact
Black 
White
At the upper range the blue line, the contrast between darker and lighter parts of the image becomes stronger and the entire image will be lighter (whitish).
The blue curve shows the relationship of impact strength and the dark (light) point in the image.
e.g.
Gentle curve: natural tone
Sharp curve: strong contrast and the entire image will be dark (white), etc.
