How to take photos on my Nikon d3000 look vintage?

I don't mean editing them on photoshop, I mean what settings and adjustments can I use on my camera to make a picture look old or vintage? I've been playing around with shutter speeds, aperatures, ect and I can't get the desired effect. Any tips? Here are some examples of the types of photos i'd like to take:

It has all to do with the post editing.

You're asking what settings? That's like asking, "what settings should i set to get the perfect photo?" This depends 100% on the lighting condition/equipment being used. There's no real "best settings" for any generic answer.

Nikon D200 gives the correct answer. There are no camera settings to take a retro looking picture.

You have to keep playing around with the shutter speed, aperture, and the ISO.

You can't TAKE pictures like that. These photos are edited to have a vintage look or they are taken with vintage cameras. To get this kind of look, download a trial at Photoshop CS5 and follow this tutorial:
