<p>Dear Sebastian, Michael Bradtke, Rodeo, Antonio, Mike, Wayne and SHun, thanks a lot for the help and suggestions. Dear Rodeo, I downloaded the viewnx2 software and the magenta/red tinge is not visible there but for one converted photo from RAW to JPEG which I have shared with you all. Will try to find out the reason now. Usually I don't process the photos at all except cropping/filling light/shadowing. Thanks once again for the help.</p>
