Do you have a chart or methodology for calculating extension factors??Perhaps the Dykinga book has that or, if not, any direction you could provide would be appreciated. Again, thanks for taking the time to explain.

Hi Bob, thanks very much your comments.? I really do appreciate them. I used a tiny amount of front tilt to get the roses in the same plane of focus.? For the second, there was a little swing too. I used an aperture of f22 in both shots. Exposure-wise, I had to factor in the lens extension into the equation, plus the filter factor.? I used an incident light meter reading, with a base exposure of 1/2 sec at f22.? Once the filter and lens extension factors were included, plus an allowance for reciprocity failure, the exposure was about 5s at f22. Hope that helps. For some truly inspirational LF work plus instruction on how to use a 4x5, I strongly recommend "Large Format Nature Photography" by Jack Dykinga. Enjoy the 4x5 system! All the best Mark.
