Stepan, The JPEG in the screenshot definitely looks better to me. The green tint in the ORF is quite strong.
Have you tried picking the incandescent preset in the white balance module? Or taking auto white balance from the thick glass bottom, for example? I have to do it for every photo from my Olys. In my case camera defaults cause a magenta cast (and so do camera presets). Regards, Artur 2014-01-31 Štěpán Roučka <[email protected]>: > Dear Artur and Matt, > > thank you for replies.
