The idea of a mask came from the connotations of a slasher. We knew that in the film 'Friday The 13th' the killer wore a mask, just like in 'Texas Chainsaw Massacre'. We also knew that to make the teaser trailer appealing to our target audience related to slasher genre we would have to have a suitable mask to fit out theme.The idea of a gas mask came about when we looked into war materials and equipment, we both agreed that a gas mask will look very daunting and would be perfect for out teaser trailer. These pictures were taken as an experiment to see how we could play around with light reflecting of the gas mask and whether we could create a light that we felt would be suitable for out teaser trailer. The end result shown is picture we felt was very effective as the red (a connotation of danger) dominates the picture like a filter.
