Thanks for pointing that out. Does the film really have such a wide exposure latitude? And what about the grain size?
In this shot, the black panels dominate in terms of surface area. With integral exposure metering, the camera automatically exposes for the brightest area, and that is the sole reason why the image doesn’t suffer from underexposure at an ISO setting of 3200.
A 400 film will never have a true ISO 3200, not even ISO 800, no matter how you develop it. Even with Diafine, Tri-X doesn’t exceed ISO 500, even if others claim otherwise. Very few people use a spot meter when taking photos and a densitometer after developing the film. This lack of precision fuels the creation of myths.
Tri-X is certainly not a bad film, but for me, purely subjectively, the HP5 has the more pleasing grain structure. It’s purely a matter of taste.
