Calibration IV - Management Drange IIb

3 rd case: the draw has a range whose pure white is higher than 0% and black densest appears before the 100%

This scenario sometimes happens if you use the same coloring for multiple processes. Changing process changes the minimum exposure time. If you research time we will find ourselves in a situation described in 2 previous posts. Otherwise we can proceed as follows:

1. Change color
   should be identified on gray scale the first white area and the first black area. then opened gray scale or color not in our software image processing. then we create a new range of color from indexed color.
   - Open the file in grayscale
   - Pass the negative image
   - Fashion indexed color
   - Fashion color table
   
   It then enters the starting coordinates and happened to get the right Dmin and Dmax. may need to be changed then the gamma (see management Drange I)
   
   
   
   
Edit
2. curve
   In this case, simply adjust the starting point of the curves that begin and end at the first white point and black point of first contact with our range of gray.
   
3. Modify Levels
   In this case, simply adjust the levels of input and output so that it begins and ends at the first white point and black point of first contact with our range of gray.
