Nice set, Tim, love the second last one with the 'wind tunnel' effect. Does the camera have a green cast or is it the weather or the processing? If that was film I'd have said it was Agfa. My Lumix FZ35 has a distinct orange bias. But they are super cameras.
I think it could have a bit of a green cast ... but it is most likely the post processing as I am on my work laptop and the screen isnt brilliant plus I had to edit online so the saturation and contrast is probably off.
It was a challenge to try and take photos out of the windscreen / window while at 80 - 100km/hr should see some of the 1st attempts with wonky horizons !!!
I use my Lumix that way all the time, yes, some come out bloody awful and some are brilliant. Tip: always wait till you are in a patch of shade on a sunny day, cuts the reflections right back.
