Which is exactly why many discerning and critical photographers shoot (or shot)
Velvia 50 at ASA/ISO 40. I regularly shoot Provia 100F with + 1/3 stop
compensation. Works for me. But with color negative or B&W film, it doesn't
usually matter because of the safety net of almost idiot-proof latitude not
available in slide film, where the difference between 13% and 18% is fairly
significant. Try it out.
