David Saffir: Managing Exposure, Lighting, and Color
May 2013 16

This is the first in a series of articles discussing proactive management of key elements involved in creating high-quality digital images. In this segment, I’ll review use of the SpyderCUBE in managing dynamic range and exposure.

If the image does not incorporate the full dynamic range in a scene, the photographer should have done this by intent.

Indeed, there is much that can be gained in terms of dramatic impact, mystery and depth by purposefully pushing the image into the darker realms of the tonal scale.
