For the 1999 eclipse I bought some sheets of mylar (I think) which can be used to photograph eclipses as a very high density ND filter. In the event the clouds got in the way, and in the short space when the sun was visible I photographed the images which my brother was projecting onto a piece of card through a telescope.
If I remember correctly I photographed a partial eclipse through the same or similar filters, but used the camera and lens to project the image onto a card, so I wasn't looking directly at the sun but could see what was happening and open the shutter. The pictures weren't very good. This is a specialist activity and you need to take advice from specialists about it, otherwise you risk melting your own eyeballs, to say nothing of damaging your cameras.
