Playing with the bulb button(the button 'B' on your fisheye) is another fun way of producing salty images.
Just by simply selecting the 'B' option,press the shutter button and trail some fancy light trails.
U may rotate the camera,rotate urself or even stay still so that moving objects with lights could be trailled.
Later,point to an object,it could be a face,a still life etc.anything could do,release the shutter button and wwaallaaahh!!:)
