Farm field at night

[padrepaul77]

I'm trying to get the hang of nighttime photography, and was recently out practicing. This image isn't all that striking, but I'm looking for advice on exposure length. Next week I'll be out in the Badlands of South Dakota and going out to Devil's Tower, and I'll have a half-full moon, last quarter. I'm hoping to capture some nice night landscape shots, and if anyone has any suggestions on exposure length time I'd appreciate it. I shoot in bulb, with a remote, and experiment with ISO in the 400 or so range. This shot is 37 1/2 seconds or so, under the moon, and maybe it should have been a little longer perhaps to light up the field a tad more? I'm guessing around 30 seconds to a minute are good options, but for any night people out there any help is appreciated. Obviously it's shorter when you have more light in urban areas, but I was looking for more shooting in rural areas. Amazing at how much light the camera picks up, even when you are seemingly far away from a city.

The other shot is a bit too noisy, and was 60 seconds, but even noise ninja couldn't get it quite right - maybe I could try fixing it a bit more, but I don't care for it with the road in front like that. Just post it as an example of kind of what I'm going for with night shots.

Thanks!
