Thats right, u can try fuji reala 100. Get it at Konotathink hard to find superia 100 (if there is ever this film)
for color negative, think the Reala is one of the more common. As far as I know, it only comes in ASA100.
the shop at the 1st floor in Penisula Plaza sells it...dunno what name, but it is quite obvious one...lotsa film being displayed...near the Bata end.
