My inability to derive reasonable coefficients appears to be because the Lensfun documentation interchanges Rd and Ru in the model equations here:
http://lensfun.berlios.de/manual/group__Lens.html#gaa505e04666a189274ba66316697e308e Reading through the source, and also looking at the hugin documentation (which uses the nomenclature rsrc and rdst), seems to support this interpretation -- and makes for a logical correspondence with the Adobe model too. With that fixed, ALPC is very happy to use a two-coefficient subset of the "full" Adobe lens model that (off the top of my head) is identical to LF_DIST_MODEL_POLY5, apart from the change of coordinate system. However, I think I'm also close to success simply fitting a PTLENS model to the ALPC model curve. I'll experiment a little more and report back. BTW I haven't tried ALPC under Wine -- I've been using it on my girlfriend's W7 PC (yes, for shame). ------------------------------------------------------------------------------ Put Bad Developers to Shame Dominate Development with Jenkins Continuous Integration Continuously Automate Build, Test & Deployment Start a new project now.
