I've had a non-technical topic on my mind for some time. Well, a non-database topic, anyway. As one who enjoys digital photography, I use my computer to prepare images for publishing. I mainly use Adobe Lightroom, Photoshop Elements and a few add-in programs. I find working with my images fun and surprisingly cathartic.
A key part of finalizing a digital image is ensuring the color is "right." The best, and most accurate way to do that is to use a calibration tool. These devices are able to measure the light from the monitor and create a calibrated profile. This process is hugely beneficial and results in colors on the screen that match what the photographer intended. Correct color on screen = correct color in print. (Yes, the printer also has to be calibrated. I outsource my printing to reputable printing resources for just that reason).
Although the initial calibration is hugely important with potentially significant results, it's recommended that calibration be performed on a periodic basis. Every time I calibrate my monitor, I benefit. The longer I go between calibrations, the greater the potential adjustment to the profile.
Another key component to correct color is the white balance: how "warm" or "cool" the color is in the image. In order to start with correct white balance, I use a gray card. (http://en.wikipedia.org/wiki/Gray_card) I especially use the gray card for pictures I know I want to be spot on, like family gatherings, birthdays, etc.
Now, moving away from the photographic to the philosophical. I have found myself lately requiring much more frequent calibration of the values I consider most important in my life. I don't know why this occurs more now than in the past -- maybe I have a heightened awareness or maybe I have more to change. Regardless, I appreciate the chance to adjust. When I compare how I live each day to the values I care most about, I can see what I have to change to get back in line.
