DOUBLE-X 黑白負片 7222，16mm

Shot a roll of this in the studio under dim light and the grain held up beautifully without going muddy. The tonal range between the blacks and whites is smooth, exactly what I want for general production work.

Shot a roll of this on a cloudy afternoon and the tonal range in the shadows genuinely surprised me. The grain is fine enough that my 16mm scans still hold detail in the highlights without looking flat.
