Colour Schemes for Final Video

I've now made my final selections for the shots I'll use in my final video. I wanted to run a few comparisons of different colour schemes to get the right look for the video. I'm looking at the original colours, cross processed, black and white and a two tone gradient map colour scheme. Here's a short video I made, just to view the images side by side:

The original colours are quite flat and boring, I feel they lack a certain visual punch to create a more interesting image. I love the cross processed shots; the contrast is increased and the colours have been enhanced to look sharper and more saturated. The black and white images have good contrast, but I feel that some of the details within the imagery are lost because they need colour to pick them out. This is the same problem I have with the gradient map images. Ultimately I feel the black and white and gradient map visuals are too unrealistic, they cause the viewer to question what they are seeing because it seems unreal, whereas I would rather an audience recognise the images and place themselves mentally in the scenes. For this reason I have chosen to use the cross processed technique to colour my shots for the final video. I will attempt to arrange them so that there is a good visual flow between shots as there will be no narrative. Sound is also something I will start to experiment with now, although there will be no real way to document the process on this blog. So far my ideas are to have an ambient instrumental soundtrack that is as subtle as the visuals. I'm hoping they will compliment and work together seamlessly.
