How to take 70's looking, vintage photos?

This is the original http://i30.photobucket.com/albums/c317/wtin/_MG_8618.jpg This is the "old" version, using Adobe Lightroom 1.31. http://i30.photobucket.com/albums/c317/wtin/_MG_8618-2.jpg The other answer is good--I think if you let the print sits in the sunlight long enough, it will fade. But I couldn't come up with an idea on how to make a photo look faded (using a film camera) unless you scan the negative into the computer and edit it with software. I am sorry I have not been very helpful. I do love my film camera, but hardly use it nowadays.

Well i think the only way is to fade the picture.. maybe leave it outside in the sunlight for about a week..

What an incredible rack. I like the yellow dress and the hairdo. Interesting pose and use of a wide angle lens. Add just a touch of yellow, desaturate, and reduce contrast a little. That would come close. Also, 70's costume and a Polaroid camera will do it.

It's not really a photographic effect. It's the clothes, hair, makeup, etc. that dates the photo.

I'd suggest looking at the prints and determining what you're looking for, the way the colors have faded, the styles of the people in them, or the way the light falls off and has defects about the edges? It should be possible to get something like this out of the camera if you overexpose your film or underexpose your prints, but your difficulty is going to be in the way even today's modern films are more flexible than they were a few decades ago. You might be able to have the printer deliberately throw the color off before they run a set of prints for you, if you know what you're looking for. The misty edges can be done by a soft focus filter, or some selective soft focus (put some grease or something on a UV filter on the front of the lens).

buy a cheap polaroid camera then scan it - if photoshop - select the entire area and use a touch of 'blur' if its too much you can 'fade blur' under the edit menu- then fade the color by using 'levels' thats the quick cure

There are various films you can by for your camera and lens filters that will give you a desaturated look. You can try looking through the assortment at B&H photo. As others have stated, the aesthetics in the picture (hair, clothes, etc. play a key role. Also remember the crop size...don't do 5x7 or 4x6...look at older film finish sizes. If you like "fun" stuff..you can also try an old Holga or Lomo camera!
