A triple exposure with rotations of the camera ans again that IR-like look. I guess it would be better to not rotate the camera from one take to the next but rather wait for different positions of the branches/leaves due to the wind. Any comments would be very welcome.
I tend to prefere the "hypothetical" image on which only the trees would exhibit this behavior, but I am glad if you find something good on the windows too.
This would be indeed one of the ways to go, Tony! I did that in another series which I'll be posting some time in the future. It was indeed very interesting.
This series is less for "mixing" many different motion blurs with a crispy clear background. It is rather for getting many copies of something that differ a little bit, and so perhaps get some clue for getting a quasi-pointillistic look. So, I guess that fixing the camera and taking some multiple exposures with many different positions of the brances and leaves with each of the frame taken at higher speeds could end up with something like many leaves spread over an otherwise "solid" background.
Thanks a lot for the idea and the encouragement. And cheers!
