Creating Texture...

I have been looking at posters for my ancillery task and I have noticed that most of them have a lot of texture which makes them look more interesting than if fewer colours were used.

For example...

This is an example of a film poster which just has a black background which is very basic:

 

This is another example of a film poster, however lots of textures have been used and it was proved to be very popular with it's audience.

 

What I need to do...

I had originally planned on having a plain background for my poster, however after looking at the comparisons between the two above I have decided that I would prefer to have my poster to have a similar effect to the 'Drag Me To Hell' poster.
This means that I will need to take images that have more dimention to them. I could photograph a black piece of paper, walls, materials or even items of clothing that have a lot of texture to them. This will ensure that the poster does not look flat or boring.
