second.lux 3.5 introduces a redesigned look system and an improved editing experience. - Redesigned look system: Choose WARM, NATURAL, COOL, or PURE, then drag directly on your photo to fine-tune its colors. KELVIN and B&W are available under Classic. - Introducing Reprint: Develop your photo in two stages with the same look to explore new color and tonal variations. - UI improvements: Refined the editor, camera, frame and margin controls, and settings, with improved previews and before-and-after comparisons. Note: Updates to image processing may change how photos appear when rendered with settings saved in earlier versions.
