Thanks Geoff for these clarifications !

 

I'll see if my supra will go blue fast with the schmidt-camera this week.

 

Clear skies !

It's as if the blue layer takes off quick, and the red and green 'catch up' later... when you expose longer. The blue saturation is even more noticeable on the compressed Web versions than the TIFF files. The 1500x1000 Web version doesn't look quite so saturated either, at least on my monitor. Thanks for the input :-)
