Visual Math Part 6 – Rebuilding (rather than extracting) contrast for more creative control

Throughout this series, we’ve explored different methods for isolating, extracting, and modifying the individual behaviors of a LUT. These exercises encourage us to think more deeply about what we find appealing or problematic in our grades. These techniques also equip us with the ability to exert greater control over the final image.

One of the signatures of any creative LUT is its contrast curve. If you learn to rebuild, tweak, and use a LUT’s contrast curve independently of its other transforms, then this opens up a whole new dimension of creative possibilities.

In today’s Insight, we’ll explore my technique for doing this in a precise yet intuitive fashion through blending modes.
