Just Alex Posted February 21, 2010 Share #1 Posted February 21, 2010 Advertisement (gone after registration) Are vignette and colour shading corrections made to the JPEG, DNG or both files? If not using an IR filter, are any colour shading corrections made to the file or just vignette corrections? Link to post Share on other sites More sharing options...
Advertisement Posted February 21, 2010 Posted February 21, 2010 Hi Just Alex, Take a look here Corrections made to JPEG or DNG file?. I'm sure you'll find what you were looking for!
stunsworth Posted February 21, 2010 Share #2 Posted February 21, 2010 Adjustments are made to both files. If you are using a lens without a filter, and use the correct setting in the menu, no colour correction is made to either file. Link to post Share on other sites More sharing options...
jaapv Posted February 21, 2010 Share #3 Posted February 21, 2010 Steve is right. Actually the corrections are made before the DNG (and JPG) file is generated. Assuming you have no lens recognition or l.r. switched off, which is advisable when not using an IR filter, there will be no lens-specific vignetting corrections either.

Just Alex Posted February 22, 2010 Author Share #4 Posted February 22, 2010 Much appreciated. If corrections are made before JPEG and DNG files are generated, why are some users still reporting colour casts on their files even when using genuine Leica coded lenses?

Jamie Roberts Posted February 22, 2010 Share #5 Posted February 22, 2010 Much appreciated. If corrections are made before JPEG and DNG files are generated, why are some users still reporting colour casts on their files even when using genuine Leica coded lenses? Wrong settings maybe? Wrong white balance? The only issue I know of right now with factory coded lenses is a red problem with some wide designs on the M9. IIRC this doesn't affect the M8.

Because that has nothing to do with these corrections. Light variation is infinite, there is only so much your camera -any camera can do in WB.Colour memory is fallible with humans - the camera often sees the colour better than you. You may not even want the original colours, etc. etc.Whitebalance is applied after writing the DNG,btw. Link to post Share on other sites More sharing options...
