My digital workflow was severely disrupted yesterday as I found that all my RAW images becomes greenish on my LCD monitor. I did some analysis and found that Ah Jon was playing with a new display card the day before on my computer. So, we figured that the colour management has messed up. Thanks God that I have a ColorVision Spyder which has quickly help me to generate a new colour profile. So, the problem is now fixed. The last time I had this problem, I need to re-install everything on my computer!
