drafting and planning - effects used on film poster

On my film poster, the background image will contain several effects that will be used to manipulate the colour and shadow of the poster creating a dark sinister effect. The image below is a draft of some effects that I could potentially use on my film poster.

This effect is called red devil and manipulates the image expressing elements of red on the image. considering red symbolises death, I felt it didn't suit the overall theme so it wont be used.

This is another potential effect I could use which is radio active this effect adds a very dark shadowy effect onto the image which is exactly want I want for the theme. However it adds too much blue and green onto the picture and it is key there is some form of colour in there.

The effect I will use in the picture is shown below. This effect is called brief encounter and I feel this is perfect for the theme of my film.
