Film Effect

First time, click File>New and set your canvas size as shown in the example.

Make a new layer .On it draw a rectangular marquee about 800 pixels width and 1000 height and fill it with black . Press CTRL+D or Command+D on Macintosh to deselect.

Select Background eraser tool. In it's options fields put Diameter between 20-30, Hardness 100% and spacing between 150-170%. I've chosen 160%. Remember that these values are variable, it depends on what canvas size you have chosen.

Click in the upper right hand corner of the rectangle. Hold your shift key down and click just below the film's lower right hand corner. Release the shift key and click in the upper left hand corner of the film. Hold the shift key down and click below the film just below the lower left hand corner. Your image should be like this: Open 3 photos you like and position them on the film as in the example.

Turn your background off by clicking the eye next to it, then right click on a layer and choose merge visible to glue the photos on the film layer. With the film layer selected, click Filter>Distort>Shear.

In the options dialogue that will appear, make your curve like in the example given. You can play around until you are satisfied with the result. Click Edit=>free transform or press CTRL+T (Command+T on Mac). Set the height to 80%, width to 70% and angle to 30 degrees. Again, I remind you that these values are variable and you can play until you like the result.

Double click the layer to bring up layer styles and blending options. Click the Drop shadow category. Set the shadow to opacity 30%, , Distance 25 px, Spread 0 and Size 5 px.

To make the effect look better, select the background layer. Use a Foreground to Background radial gradient, starting from the middle of the canvas, right under the film. For my example, I used Foreground #132844 and Backgound #ffffff.
