For architectural photography i use (i shoot 4x5 for architectural which limits my recommendations):
- Portra 100t. Exposed 50-64. Best all around film for mixed lighting. Npl has problems with shadows requires an exposure of iso 50. The extra layer for flo lighting actual makes filtration more difficult
- 160vc exposed 50-80. Lacks the 'punch' i would like, but is a good film for daylight especially when exposures are long.
- NPS exposed at 64 to 80. Terrible for long exposures narrow exposure latitude. Good colours moderate contrast.
For tranies I like RTP, Provia, EPP[/list]
