This GUI controls a program that sends image data to a film recording device. Plot Status progress bars show the data transfer in process. Note that color data is stored in Red, Green and Blue Field Files. The Dialogue Box displays useful information and instructions. |

Here we have a GUI that controls a program allowing an operator to create brightness and contrast look-up tables to optimize using the full dynamic range of the film in use. In essence, this is a Gamma Correction program to calibrate the recording device and film combo. |

This GUI is used to display graphs showing the film densities achieved as a result of the
Gamma correction process. Video DACs are 12-bit (0-4096). A graduated step wedge is printed to film
(BLUE-PREVIOUS). The desired response is shown (BLUE-IDEAL). The table-corrected result is shown
(BLUE-CURRENT). The result is acceptably close to the ideal. As you can see, this graph represents the blue field data. |
