Dear Sir/Madam <p> I am having trouble writing an essay on the large format camera as part of my Btec Nd photography course. I was hoping that you could help me? <p> I need to know more about shift, swing and tilt movements and the implications of schiemphflug and camera yaw. <p> If you could help me out this would be of a great help. <p> Thankyou <p> Gina Spencer.
