Wanstead Flats East London

This was my first attempt using this camera as has been begging me to go out..The film holders are very big 11x14 and take 10x12 plates so i used a piece of thin ply and taped Paper to both sides .. exposure was about 1min 40sec at F45 using a agfa repromaster 213mm and it covered without a problem. I heard that these lenses where soft at edges but judging by the paper neg it seems sharp indeed i only had one film holder and hope that at least one would work .. this was the resultthe scan cannot fit all the picture being a4 scanner not sure how to work round that problem?
