Default Accurate dusk photographs with Canon 500D

I have noticed that if I shoot at dusk, or in shaded woods the photos are not as I see the subject. They are lighter. I know it is something to do with the fact that I shoot on auto ISO.
When I used film I had no such problem. I have set ISO at 400 and this is close to what I see. [Even though the shutter speed in slower.]

What settings should I shoot at [ Dusk or darkish areas] so that what I see is what I get when I look at my photos?
Thanks.

It isn't a matter of auto ISO -- it's a matter of using a light meter. The purpose of the light meter is to figure out how to make what it meters average out to mid-grey when viewed in black and white. But, as dark settles in, the scene may not look right when set to mid-grey. So you need to either shoot in manual mode and set the exposure yourself or in one of the semi-auto modes and use exposure compensation (my personal choice in most cases) to match what you are actually seeing. Typically, this is an iterative approach. If you can trust your LCD, it is easier. If not, you need to develop a sense of how dark your photo will end up looking when the histogram is centered at various places along the x-axis. The "royal road" to learning this is to use Capture NX2 and play with the Exposure Compensation function in the Quick Fix section. It will show you what would have happened to your image if you had set the EC differently, and will allow you to actually set it after the fact -- all part of the magic of shooting raw...

Dawn and dusk can be a bit tricky. When you are shooting towards the
sun, you will often seen very big differences in illumination between
sky and shadow. This tends to confuse zoned metering systems like the
evaluative metering mode which is the default setting in the T1i.

Try using centre weighted or spot metering instead. When the
range of light exceeds the dynamic range of the camera, you
will have to choose between very dark shadows or white (blown out)
sky. A graduated ND filter can help sometimes.

You might never achieve the result you are looking for. Digital
and film cameras have less dynamic range than the human eye.

If you use a tripod, you will often be able to shoot at ISO 100. This
will reduce noise in the darker areas.

The tripod will allow you to use a long shutter time:



and/or small aperture:
