New to Nikon D5100. What menu to take long exposure shots?

Just as the title says. I'm new to the D5100 and I can't figure out how to take long exposure (longer than default settings) shots. I'm new to DSLR cameras in general.

First, you really need to read and study the Owner's Manual for your camera.

Second, watch this video tutorial: http://www.nikondigitutor.com/eng/d5100/index.html Who better than Nikon to teach you about your Nikon D5100?

What you need to learn is how to use the B (Bulb) setting on your shutter speed for exposures longer than 30 second. In B you can keep the shutter open as long as you want. Your camera must be on a tripod and you'll need a remote release like the Nikon ML-L3.

While reading and studying the Owner's Manual and watching the video look for any cautions or warnings about making exposures longer than 30 seconds. Sensors do heat up you know so you don't want to risk overheating your sensor and damaging it.

Learning about the Exposure Triangle is something you need to do (as does anyone interested in photography) and this site offers a good explanation:

By understanding the relationship between Aperture, ISO and Shutter Speed - the Exposure Triangle - you won't be out trying to take a 1 minute exposure at f16 (or any other aperture) in daylight and then coming in here asking why your pictures are all white (blown out is what its called in photography).

I use and recommend this site for exposures in low-light:

I used the Scene 'Distant view of city skyline or floodlit buildings' and ISO 200 for these pictures of the Louisville, Kentucky skyline:

100mm @ f11, exposure of 30 seconds.

200mm @ f11, exposure of 30 seconds.

The way to take long exposure photgraphy with the nikon d5100.
There are two ways of doing it #1
1.go in the mode with the S (shutter speed priority) set it to around 25-30 seconds.
2.go in the mode with the A (aperature priority) set it to a larger number so everything is in focus.ex. 22. An aperture of 22 will make everything in focus.
3.next turn it to M and your shutterspeed and you aperature should be set.
4.set a low iso.ex. 100
5. If the light meter says it is too bright then you have to shoot when it is darker out.
#2
1.set your aperature to 22 in A mode
2.set a low iso
3.go into M mode and keep turning the dial until it says bulb (now you control the shutterspeed). For clear photos and to prevent camera shake you should purchase a remote.
4.usually the light meter will say it will be too bright, so you can either shoot when it is very dark out, or you can buy a neutral density filter and this will make everything darker for you.
The tools that you will need for a successful long exposure shot is a remote, tripod and a and filter

Besides reading your manual you should get this DVD it takes you into depth of your camera "showing" you how to use your features in stead of just the black and white words of a book. Quickpro Camera Guides are great
