I have two Olympus cameras, an OM-D EM10 and an older E-PM1. Both cameras have an Auto white balance setting, several presets and custom options. It seems to me that LR is not aligned completely with the WB temperature as per the manual. For example, just take four settings by way of example. Both cameras as per the manual will set WB as follows: Sun: 5300K Shade: 7500K Cloud: 6000K Flash: 5500K This is confirmed by the Olympus Viewer program. When I import into LR and go immediately to Develop, no Develop presets, and look at the WB I get under As Shot I see: Sun: 5000K (EM10) 5100K (E-PM1) Shade: 7250K (EM10) 7600K (E-PM1) Cloud: 5700K (EM10) 5850K (E-PM1) Flash: 6500K (EM10) 5850K (E-PM1) Why are these values adrift from the Kelvin values that Olympus have defined for these settings, when it is As Shot? I could understand it if I were using one of the Lightroom settings. What is weirder is that if I set a Custom White Balance of say 8200K then do the same thing and look at the As Shot figure, I see 8300K for the EM10 and 8800K for the E-PM1. Is LR ignoring, or at least re-evaluating the WB settings on import? As it is RAW I know it isn't a big deal but it is slightly annoying if you have set a Custom WB in camera to reduce workflow only to find it has been "tweaked" without your knowledge. Any ideas?
