The first is called bokeh. Bokeh are the soft circles in the background of some photographs made by shooting with a large aperture.
I first found out about the bokeh effect from this website:

Apparantly it is possible to change the bokeh from circles into other shapes simply by cutting out a ciclre in black paper that can fit over your lens and then cutting the desired shape into the center of the paper.
Here are some examples

I thought I could give this a go so I cut out a small cross and stuck it over the camera lense.
They didn't work out very well, maybe I had the aperture wrong, regardless, it is something I'd like to look into at another stage.
The other light filter that I tried was coloured celophane.
This worked and reminded me of my first project with coloured television light; however the images I took had no substance to them, they were just images shot from sitting on the couch. If I was going to continue using celophane I would need to plan my images and capture something worthwhile.
I will continue exploring.
