One of the things that really attracts me to blending modes is the ability they have to soften an image. By blending images they take on a dream like quality that is a lot softer and more interesting than the hard lines of a straight photo.
This visual style is something I would like to experiment with in my assignment to see what can be achieved by applying a range of blending modes.
There is also a depth of colour that can be achieved (although it is usually quite unrealistic). This element of fantasy within a landscape is very appealing.
