Calibrating My Computer Monitor

I went out to shoot for some more exercises today but the incessant rain drove me in to a fantastic camera shop by the name of Park Cameras. This place has a large internet based business so the prices are always keen. I ended up buying a device to calibrate my computer monitor. The difference post calibration is really quite astounding. My images which I have dutifully been processing in Lightroom and underexposing a little as they seemed too bright all look too dark now.

I am not going to go back and edit photographs I have already submitted. However, there should be a big difference in future uploads. I am guessing that on uncalibrated pictures my future pictures will look too bright. However, I will be happy in the knowledge that my prints will come out as they look on my screen.
