How good is this film? How does the grain compare with\nregular 200 speed film? I want to use it to take photos\nof indoor events (get-together, etc.). I don't intend to\ntake natural light photos, but use just the built-in flash of\nmy Pentax ZX-5. Will it work? Or will the snaps be\ntoo dark and/or grainy?\n\nThanks in advance,\nPinaki.
