Colour Management #1 - Calibrating and Profiling a Display Device


Calibration #1
2.3.2011


Task: To be respoinsible for maintaining the calibration and profiling of one of the display devices in the photography area for the remainder of this semester. This will involve carrying out an initial calibration/profiling exercise which will be reviewed in class in week 11 followed by three more follow up calibration/profiling exercises at regular intervals during the semester.

1. Each person will be allocated a monitor.

2. You will set the desktop of your allocated computer to the ‘Grey Desktop’ image (available on eLearn).

3. You will perform an initial calibration/profiling of your allocated device and post the results on your blogs before start of class week 4 (9th March). We will review the results in class.

4. You will profile again and post the results by week 6 (23^rd March).

5. You will profile again and post the results b

y week 11 (11^th May).

6. Each time you create a profile you will -

• Capture a screen image showing the results of the calibration ( see below).
• Name the profile ‘YourName_LCD_Monitor_yymmdd.icc’
• Apply the profile to the student login.

ICC Profile Location






Results/Observations:
The ambient light is not ideal. There is a window directly behind the computer as well as overhead lights. The ambient light readings indicated that the colour temperature was slightly to warm. This would be due to the overhead lights but the window light seems to cool this down in comparison to some computers at the front of the classroom facing away from the window are considerably warmer. The illuminance is also too bright in this circumstance.

From the summary given we can see that the target temperature and gamma were both achieved. The graph shows that the red values are correct where as the blue and green values are not ideal.
