Filter experimentation

After buying a load of filters off ebay for dead cheap I thought I would see what effects each of them had, as half of them weren't labled so I didn't know what each of them were. I set my camera on a tripod and correctly exposed the shot, then left it in the same position so that all the images would show exactly what the filters did, including exposure differences and colours. Some of the images really obviously don't suit the picture, but thats helped me to realise which ones would fit this kind of shoot. The bottom image has no filter on.
