Editing using iPad

For these images I used apps on my iPad to manipulate them.
The apps I used were: Brushes, Sketchbook Pro and Colour Effects.
I changed the pictures into black and white then added the colour back into some areas. The colour I am keeping is blue. I then added text to them and layered them up with other images.
My favourite is the one which contains he word 'Bolseńa', this is because the colour difference is obvious and it is a simple image.
