If I remember correctly, all you need is a track on Eifel, set the time to 06:00, put the surface water level to 100% (or maybe a bit lower, experiment a little to see what suits you best) and then point the camera in the general direction of the sun, and you're golden. Thanks btw.
I remember Eifel having crazy exposure levels when it was released, is that still the case? As far as I know, there's not been a GT6 update since Course Maker, right?
Oh, no problem. Might have to check out what I can cook up with Photo Mode on Eifel using your settings.
