How they work together

Diafine: Fine grain, high acutance, normal contrast. Good shadow detail with effective speed increase.
Street Candy Street Candy MTN 100: A repackaged German motion picture stock, widely believed to be ORWO UN54 from the Filmotec factory in Wolfen. Delivers a distinctive cinematic look with medium-high contrast, fine grain, and excellent sharpness. The tonal range favours deep blacks and crisp highlights, making it well-suited for street photography and documentary work where you want images with presence. Processes in standard black-and-white chemistry. The motion picture heritage shows in the results—there's a certain character that feels different from traditional still photography emulsions.
Notes on this pairing: 3 min Bath A + 3 min Bath B. Datasheet gives no temperature; 20°C assumed.
