However, given the focal length, I think that the IR/UV filter is irrelevant. I suspect that a film camera would record the same in that situation. Quite unimportant for this shot anyway.

I'm not optic/techno enough to know exactly what the relationship between the IR and chromatic aberration may produce. no IR filter on the lens and camera programmed for IR Filter and lens detection so? I'll try to do some comparison images over the next week with different program settings and see if it renders any differently Fond regards, George george@imagist.com http://www.imagist.com http://www.imagist.com/blog http://www.linkedin.com/in/imagist On Dec 30, 2008, at 2:43 PM, Chris Saganich wrote: > Nice family gathering. > > So what is that green outline around the duck heads in the background? > IR interference? > > At 12:20 PM 12/30/2008, you wrote: >> not a spectacular wildlife photo >> simply a quiet moment >> >> <http://www.imagist.com/blog/?p=670> >> >> Fond regards, >> George >> >> george@imagist.com >> http://www.imagist.com >> http://www.imagist.com/blog >> http://www.linkedin.com/in/imagist >> >> >> >> On Dec 30, 2008, at 8:11 AM, Edward J Caliguri wrote: >> >>> ANY combo of camera,film, digital, glass etc. works - whatever fits >>> the bill >> >> >> _______________________________________________ >> Leica Users Group. >> See http://leica-users.org/mailman/listinfo/lug for more information > > Chris Saganich MS, CPH > Senior Physicist, Office of Health Physics Weill Medical College of > Cornell University New York Presbyterian Hospital > chs2018@med.cornell.edu > http://intranet.med.cornell.edu/research/health_phys/ > Ph. 212.746.6964 > Fax. 212.746.4800 > Office A-0049 > > > > > > > > > "I am the radiation" > _______________________________________________ > Leica Users Group. > See http://leica-users.org/mailman/listinfo/lug for more information _______________________________________________ Leica Users Group.
