photolandscape Posted August 20, 2007 Share #1 Posted August 20, 2007 Advertisement (gone after registration) Presently on Easter Island, where my M8 and lenses are being tested and are holding their own. I noticed something new last night that may have been introduced in the latest firmware version--under lens detection--the choices are ON, ON w/IR Filter, and OFF. I am using IR filters at all times. Do I need to set the menu to ON w/IR filter to activate something in the software to help with IR filtration, or is the ON setting enough. I hadn´t noticed this w/IR Filter setting before, so am wondering. Thanks. Link to post Share on other sites More sharing options...

Guest tummydoc Posted August 20, 2007 Share #2 Posted August 20, 2007 If your wide-angle (<=35mm) lenses are coded and your filters are Leica-brand, the ON+UV/IR will correct the cyan corner vignetting, to a greater or lesser degree depending upon the light and aperture. With lenses >35mm there is no correction needed, and with un-coded lenses there is none applied. Link to post Share on other sites More sharing options...

Guest tummydoc Posted August 20, 2007 Share #4 Posted August 20, 2007 I only can attest that it applies to DNG. I haven't found anyone willing to admit they shoot JPEG and neither will I Link to post Share on other sites More sharing options...
fotografr Posted August 20, 2007 Share #5 Posted August 20, 2007 The correction is applied in RAW. I learned this the hard way. After using a non-coded lens with Lens Detection in the "off" mode, I shot a job almost exclusively using the 24mm Elmarit and forgot to turn the Lens Detection back to "On + UV/IR." I ended up with cyan corners and it was a complete pain in the ass to remove. I never shoot anything but RAW. Link to post Share on other sites More sharing options...
Ian Kerr Posted August 20, 2007 Share #6 Posted August 20, 2007 Brent, you are probably aware of CornerFix, but in case not, have a look at "http://sourceforge.net/projects/cornerfix/". It should remove the pain-in-the-ass factor. Cheers Ian Link to post Share on other sites More sharing options...

Guest tummydoc Posted August 20, 2007 Share #9 Posted August 20, 2007 CornerFix is a stand-alone not a plug-in so if your Mac is like mine you can run it in Windows without much more hassle than those with PCs. Link to post Share on other sites More sharing options...
Ian Kerr Posted August 20, 2007 Share #10 Posted August 20, 2007 Bill, I believe there has been discussion about developing a MAC version, but I am not aware of where that ended up. For now, at least, it is Windows only as far as I know. Cheers, Ian Link to post Share on other sites More sharing options...
Bill W Posted August 20, 2007 Share #11 Posted August 20, 2007 My Mac is an older G5 and not the intel processor version on which it might run. I am going to upgrade when the new operating system is out some time in October. Leopard I think it is. Link to post Share on other sites More sharing options...

hdrmd Posted August 20, 2007 Share #13 Posted August 20, 2007 A program called Parallels allows you to run Windows XP on the newer Intel Macs. You can then use CornerFix. Regards. DR Link to post Share on other sites More sharing options...
