Scott, Doug,
Thanks very much for the information.
Over the previous two days I have scoured the GetDPI forum for information in order to educate myself about DMF, in particular tech cams. I'll be honest, when I:
1. Read a thread that was started by owners who, upon receiving their then new-to-the-market IQ180 discovered severe lens cast with their Schneider lenses, or;
2. First read this thread discussing the centrefold effect...
...it made me
extremely nervous, to the extent that I would say I was fairly 'spooked' by the threads in question.
However, having read through (1) above in its entirety it is clear that, at least with Rodenstock wideangle lenses, the issue of lens cast can be addressed. In addition, Capture One v7 apparently significantly improved upon LCC processing compared to its v6 predecessor that existed at the time the IQ180 was released. Moreover, one has only to see the clean, white image that results after an LCC has been processed, shown in
this thread, to obtain visual proof that lens cast can (IQ160 was used in that test) be addressed...at least when a lens is unshifted.
