[LargeFormat] rising front

[philip Lambert]

Thanks - I understand you but you did not exactly answer my enquiry. On the
other hand nobody else answered at all.  It must be the holiday season.. I
am now trying to get some rising front on my small-format Nikon using a 5x4
90mm Angulon but am still waiting for the engineer to do his bit.  Philip
