I was going to call this Boston Blue Line. But the “Train to Wonderland” sounded more evocative.
Boston’s Blue Line subway offers a great example of when to make good use of a digital camera’s ‘auto white balance’ feature. This is in contrast to yesterday’s post describing when to avoid ‘auto white balance’.
Auto white balance is a good tool when exposing photos under fluorescent lighting, where the color balance varies with the color temperature of the bulbs. With this setting the camera will automatically select a neutral white that avoids unnatural tints caused by color-spikes in the bulb’s spectrum. These artificial bias-tints are typically invisible to the eye but produce a strong color cast in photos.
