Yes, of course large format is much more expensive than roll film per frame but, that is ignoring the fact that we tend to expose far fewer frames of LF. That high per frame cost along with the effort involved in setting up the camera make you think about what you're doing and there fore, you use far less film (and get a higher ratio of "keepers"). So, the total photographic expense over a year is lower with LF than it is with roll film...becasue there is less waste.
