This is all very interesting - Gary do you have any of your iomages on the
web?  A range of greys with Konica 750mm !!!

The thing that attracts me to using Konica is in fact the high contrast - I
like the almost lith effect that is possible.  Have just posted a couple
more images on a growing web site which is commercial so be warned (an
attempt to fund my next photo trip back to the USA) - have a look in the
gallery section.


All the best,
