I've started to use a 5x4 camera, mainly using Acros 100 film (given it has minimal reciprocity issues, and I typically photograph architecture at night).
I suddenly thought that maybe it makes sense to use my Digital SLR (a recent one, the Canon 40D) to get an accurate exposure reading. The main benefit that I can see is that I can check a whole load of various exposures on the DSLR's rear viewing screen to chose which one is the best-balanced and the most accurate for the scene in front of me.
I haven't yet had the opportunity to use this "technique" in terms of using whatever exposure appears to produce the most accurate image on my DSLR's rear viewing screen and simply using that shutter & aperture combination on the 5x4.
Does anyone use this "technique"? Does it work in reality, or am I missing something?
