I've taken this image on a digital camera. I took the image in my bath, the fake blood is just food colouring that I simply splashed against the tiles of my bath walls.
I uploaded the image onto photoshop and adjusted the colours and shadows. In the original image the blood was too pink and there were not many shadows so it looked very flat and 2D. I adjusted the size and made the image a JPG and then unloaded it onto my blog.
