This video tutorial by Denny Tang from Photoshop Tutorials (narrated by Dean Wendt) explains how to use tone curve and hue/saturation adjustments to make various film effects to add to your photos.
The two-layer technique shown in this video can be used to create nearly any film effect and should also work in Adobe Lightroom, Phase One Capture One, Adobe Premiere and a lot more programs other than Photoshop.
The video starts with an explanation on how to work with a tone curve (it is less complex than you might think if you are not familiar with it and the explanation in this video is one of the best that we have seen to date). After you understand the basic idea of of the tone curve you can do many things especially if you remember that many of the film-like filters used today employ high/low contrast look.
Another thing that you can do is to tint the shadows and highlights. Choose the color balance tool and choose the shadows to add a bit more color (say blue with a little bit more warm) you can do the same thing with the tone curve (by selecting a specific color and working with it just like we did before with the brightness and contrast).
