The Second Step to Digital Image Excellence

Darrell Young (DigitalDarrell) on November 4, 2013


Keywords: digital, calibration, monitors

So, you've bought that Nikon® digital camera and lens you've wanted for a while. The first step is complete! What is step number two? Get a printer? Nope! Step two is to buy a monitor calibration system. Especially if you shoot RAW (NEF) images!

Why is that the second step to digital excellence? Well, it all boils down to a capability our human brain has that can hinder our ability to process accurate color images in our computers, after the fact. "What is that capability," you might ask? Our brains are selective and adaptive. Our cameras are not nearly so powerful. What I am talking about is simply this—when you walk into a room from outside and see a family member reading a book under a tungsten lamp, what color are the book's pages to you? White, right? "Yes," you may say, "but, so what?" Well, if you took a picture of the book under the lamp light, those "white" pages would have a strong orange color from the tungsten light. Your brain sees white, even though the light is truly not white. Your incredible brain has automatic white balancing! That's a real problem for photographers.

Following is a sample night-time image that I took recently. It has about four types of lighting in the image. I was doing time exposures while waiting for a nice lightning strike. It was storming while I stood on the front porch with my Nikon on a tripod. When I looked at the scene, I saw nice white lights, and finally a small lightning strike in the background. However, when I pulled the image up on my computer later, I was amazed to find weird light sources and color casts.
