    pub film: String,
    pub minutes: f64,
    pub temp_c: f64,
    pub gamma: [f64; 3],
    pub d_min: [f64; 3],

}
Expand description

A film’s characteristic curve, sampled over its exposure range.

This is the developed curve itself, not the nine-patch wedge the densitometer reads: a panel that drew the wedge would show a straight line where the film has a toe and a shoulder. Every development of a stock is sampled over the same range, so a strip’s curves overlay point for point.

Fields§

§film: String

The film.

§minutes: f64

The development.

§temp_c: f64

The developer’s temperature.

§gamma: [f64; 3]

Contrast per layer.

§d_min: [f64; 3]

Density floor per layer.

§d_max: [f64; 3]

Density ceiling per layer.

§log_e: Vec<f64>

The log10 exposures the curve was sampled at.

§density: Vec<[f64; 3]>

The developed density per layer at each sample.
