I almost always use daylight-balanced film in daylight, but once, just for fun, I used Fuji 64T tungsten film outdoors. I was hoping to get a saturated blue with a little cyan (I'd seen it in a book), but the chromes came back a rather muted blue - it was blue, but not very saturated and certainly without much cyan. The effect was like a strong color-cast from the sky. I'd like to get a blue with a bit of cyan, and I'd like to avoid filters (hence the tungsten). Could somebody recommend a film that would give me this? Thanks.
