Very nice.
I like #3 best.
One chalenge while using this lens is, when placing the horizon in the middle to avoid the curve, is to give the impression that it is not tilted.

Good point... Another is to avoid flare from the sun.. not so easy to just tilt the lens or hide behind a tree.

What is RG830?
How did you get the IR effect? Converted camera?
Thanks.

yes.. the UV/IR cut filter that was stock on the sensor was replaced with an 830nm long pass filter.  RG830 (Red/Green) is a Schott Glass designation for the filter.

They look familiar to me, but I've never gotten bored.
