LYGIA Shader Library

exposure (lygia/lighting/exposure)

Calculate camera exposure

Use:

float exposure(float aperture, float shutterSpeed, float sensitivity)

Check it on Github


#ifndef FNC_EXPOSURE
#define FNC_EXPOSURE

float exposure(float aperture, float shutterSpeed, float sensitivity) {
    float ev100 = log2((aperture * aperture) / shutterSpeed * 100.0 / sensitivity);
    return 1.0 / (pow(2.0, ev100) * 1.2);
}

#endif

Use:

float exposure(float aperture, float shutterSpeed, float sensitivity)

Check it on Github


#ifndef FNC_EXPOSURE

float exposure(float aperture, float shutterSpeed, float sensitivity) {
    float ev100 = log2((aperture * aperture) / shutterSpeed * 100.0 / sensitivity);
    return 1.0 / (pow(2.0, ev100) * 1.2);
