Hi Marco,
"0" is one of the values of a 16-bit file, so the brightest white would
only go to 2 to the power of 15.
In other words, the values go like this:
1. 2 to the power of 0 darkidiest dark
2. 2 to the power of 1
3. 2 to the power of 2
4. 2 to the power of 3
5. 2 to the power of 4
6. 2 to the power of 5
7. 2 to the power of 6
8. 2 to the power of 7
9. 2 to the power of 8
10. 2 to the power of 9
11. 2 to the power of 10
12. 2 to the power of 11
13. 2 to the power of 12
14. 2 to the power of 13
15. 2 to the power of 14
16. 2 to the power of 15 whitiest white
