Maris, you have chosen the subject very well. Water, goes black, some clear sky, goes black with the white clouds making it more interesting. Lots of green stuff, grass and close trees emanating IR, wide angle lens to get most in focus. I like the central tree bending in the wind.
Best of all, probably shot around 2 hours either side of local midday time.
I've done massive amounts of IR using Kodak Infrared film in 35mm, even have a technique down pat where a light meter isn't required.
This is pretty good, really good in fact.
I'm doing a lot of running around at the moment, so picture taking is on the back burner. I wouldn't mind having a crack at some IR 4x5" photography later this year when we envisage some extensive travel in Australia. I'll need to check if my bag bellows are IR safe for 65mm stuff though.
