The Exposure control adjusts the overall brightness of the picture. It does not operate like a basic lift or offset tool—instead, it works in relation to the tonal range defined by the film model. This helps retain highlight detail and shadow depth without flattening the picture. In simple terms, this control lets you make the picture brighter or darker while keeping the tones intact and avoiding the harsh look that can result from traditional digital exposure adjustments.

On the left, exposure maxed out. On the right, default.
