More images from the Silent Pool and Sherbourne lake, on the Albury Estate near Guildford.
Taken on a miserable rainy day from under an umbrella with a full spectrum converted Lumix DMC-GF3 fitted with a 590nm infrared filter on the lens.
The lakes were flowing through heavily with the amount of water coming off the surrounding land.
These were shot this morning from the top of the hill at Newlands Corner near Gulidford, with a Lumix DMC-GF3 I've just converted to full spectrum. It was a very dull misty morning and I was looking for somewhere to test out the camera. Then as I neared the brow of the hill I cleared the mist into early bright sunshine. Then I realised the amazing vista opening up to my right. The trees and lower hill tops just poking through the mist below. It was stunning. I missed the best of it though, by the time I got parked and fumbled my camera into life it was going fast. I just had a UV filter on the lens, so this is predominantly visible + IR. And dammit, would you believe it, I just noticed a speck of dust on the sensor ... missed that !
I spent a day exploring the beautiful campus of Berry Collage in the hopes of capturing some of it. As usual, I had two cameras, one set up to shoot full-spectrum. On the campus they have a couple of these old structures and I fell in love with entire scene. I fell in love even further when I looked through my full-spectrum camera with a 470nm infrared filter on the lens! Then it took on a magick all its own. So I had to make sure I grabbed it.

This was taken along the River Wey above Triggs Lock. Shot with a Full Spectrum converted Lumix DMC-G1 with a 590nm IR filter fitted on the lens. This image is R-B swapped.
That's a monochrome sapia development and a horizontal 16:10 crop, 17083 x 10677px ~182,4MP, of this original:

Maybe I overdid it a little with the shadows? Let me know what you think about it..

"False Color" red/blue channel mixed JPEG from my DIY fullspectrum modified GH3 with B+W 090 Red+IR filter. The new Lumix 12-60mm zoom lens is perfect for infrared work. I haven't seen any hotspots or bad flaring as of yet. It's weather sealed too!

Full spectrum
This image requires some explanation. The blue colour of Blautopf is induced by small silicate particles that, thanks to Rayleigh scatter, predominantly scatter back blue light to the surface. Full spectrum had very intriguing effects:
1. Outside of the water, full spectrum (and therefore infrared excess in the leaves) dominates at this white balance
2. Below the water, there is almost no infrared emission. Water is much more absorbant in the IR and Rayleigh scatter is highly dependent on the wavelength!
3. At the water surface, due to the wavelength-dependency of the refractive index, there is an almost complete reflection of the infrared light. Hence, the reflection appears slightly brighter (and whiter) than the actual trees

Darker ND gives more IR character, with quite rapid change in the first bit of adjustment.
