Are there any good ressources for getting started with pinhole photography? Preferably books ? Especially I would like to know what (comercial) pinhole cameras are out there, how to choose the right one, how to build my own one and how to correctly expose and develop the film. Also I have found a 6x9 homemade pinhole camerea, it is a modified Agfa Clack with a 0.4 mm pinhole and built in yellow and orange filter. I kind of like the idea of a 6x9 pinhole camerea because of the costs also it has a viewfinder wich I think could come in handy as well. What dou you think ?
