The "yellow" problem occurs with both the ProCam and native camera application. It only occurs in certain lighting. It occurs with or without flash. I have made extensive "fiddles" with the adjustments (white balance, shutter speed, etc.) and while there are certainly variances - none are perfect. Outdoor pics - perfect in any lighting. Indoor pics - in certain lighting - perfect. But the yellowing happens frequently with typical indoor lighting such as the dog pics from another post early on this thread are very typical and cannot be corrected through settings. In the Nokia Support Discussions, a Nokia moderator entered that they have acknowledged this problem and are working on a fix...... but no timeline offered.
