It's easy to forget about. You use it for just about everything in life, you rely on it more than you know, but might not even know how inaccurately you are viewing and editing the digital world. Out of all of the gear photographers lust over, camera bodies, lenses, and the thousands of dollars spent to acquire these light capturing tools, most forget about one of the cheapest and most important pieces of gear they need. If you are a photographer and have not properly calibrated your computer monitor, you need to stop editing photos and get on this. I repeat, do not edit another photo before taking the steps to ensure proper monitor calibration.
