How to make clips look like a historical flashback

Hi,

In many history documentaries they include dramatised flashbacks that often have a stylised look... and also hides the fact that the reconstruction is low budget.

Does anyone have any idea of how to achieve this kind of effect?

Thanks,

There are many different looks that are used to indicate a flashback. Most common are a vignette, sepia, B&W, or bleach bypass -- or a combination of these (try bleach bypass with vignette)
