I remember some years ago seeing a free gift with a photo magazine which allowed you to calculate the ange of the sunrise and sunset at a given latitude - looked a bit like a compass as far as I can remember. I didn't buy it, but now I kind of regret it.
I'm currently planning my shoots for the coming season and I think this could be a very usful gismo for planning getting the sun angle just right for a given subject. I have trawled the web but surprisingly found nothing about this gadget. Anyone know anything about this?
