I believe it requires a long development.
Like I said, meter for your shadows, and manage the contrast in the scene.
Also, the actual manufacturing quality of the film is up to shit, so if your images have large ares of continuous tone you will probably reveal defects in the emulsion, like spots and streaks.
Pic related, I'd call this pretty much unusable as an image, but this is from the same roll as my tree-trunk photos, which have enough contrast and detail to mask these problems.
