This is going to be the first of probably several posts. My objective is to add a 6X7 or 6X9 rollfilm back to a view camera for architectural photography in New York City. Since I don't have a car and must walk for all photo outings, I am trying to see if I can make a field camera work. It appears for the medium format film, I'll need to work with around a 67mm lens, or wider for interiors. I want to use the roll film back to lower my cost per shot (film cost plus development) from $5.50 per shot to $1.4 per shot and still have a very sharp, good sized negative from which to work digitally. From what I've read thusfar, perspective control, mostly for converging verticals (because I don't know much about adjusting for planes of focus yet), is accomplished with front rise. But I have also read that for really tall buildings, lowering the rear standard is often necessary. I have seen on a view camera forum that the lowering of the rear standard, not possible with field cameras, can be simulated by by tilting the whole camera bed upward but that this would require being able to tilt the back and front of the camera forward so they are parallel to each other and the building. Comments or corrections please?
