While visiting my cousins in Alabama, I did my normal routine of walking around and photographing anything and everything. I happened to be shooting with a full-spectrum camera, so the December trees looked amazing. So of course I had to capture them against the winter sky. They seemed happy to cooperate.
This image was taken with a full-spectrum converted camera without an infrared filter. It was taken in RAW and processed in Linux using RawTherapee.

Ok, cette photo est manquée. Il y avait un nuage de mouches noires entre moi et les nuages. Étrangement elles ne piquaient pas.
Souvent on voit dans les annonces d'objectifs usagés: l'élément frontal est égratigné, mais ça ne devrait pas affecter la qualité de l'image. Pensez-y deux fois... En tout cas avec un grand angle, dès qu'on ferme un peu, on voit très bien ce genre "d'imperfection" de la nature.
Ok, this picture is a fail. There was a cloud of black flies between the clouds and me. Strangely they didn't bite.
Often you read in used lenses offerings, for instance on eBay, that the front element is scratched and that it shouldn't affect picture quality. Think twice... At least on wide angles at small apertures, this kind of "defect of Nature" can be easily seen!

It can be seen that there is a pronounced center hotspot in case of shortwave- and longwave-pass filters. In case of bandpass filters with high amount of visible spectrum the hotspot is significantly less pronounced. Are there any other EF-M lenses without hotspot?
aperture: f7.1

DIY 4x5 Scanner Camera. Xenar 180mm lens @ F/4.5
Honeysuckle shot wide open. Windy and overcast. I'll try and get this again without the wind.
This is additive color. An Infrared shot combined with Yellow and Blue.
I converted my DP1s to full spectrum a couple of months ago, but never got a chance to really go out shooting with it. I still haven't, but i decided to post a test shot.
I set the white balance off of the dead grass in direct sunlight, and it seems that i got lucky. This image accurately shows that my grass is dying, but my palm trees are doing quite well!
The conversion wasn't that difficult, but i did damage the ribbon cable for the screen while taking the camera apart. A word of advice: DO NOT try and disconnect this cable. I realized later that i could have disassembled the camera without disconnecting it.
So now i have to hook the camera up to my TV to put my settings in, then i try not to touch any buttons while i'm out and about.
Images taken along the River Wey just below Guildford.
These are some of the first images taken whilst testing out a newly converted full-spectrum Lumix GX1. These were taken with a 590nm Infrared filter on the lens. They were R-B channel swapped in CS6 then processed and converted to mono in LR5.

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.

Photographed with a full spectrum infrared camera and using a 470nm filter. Taken at the Nelson Ghost Town near Las Vegas.
To recap: The Nelson ghost town is about 1 hour south east of Las Vegas off Hwy 165. Originally a rough & tumble mining town begun in the 1860s, the town was purchased by Tony and Bobbie Werly in 1994 who then restored the old buildings. Mr. Werly also collects antique vehicles & there's about 60 classic cars, trucks, buses and even 2 airplanes on the grounds. None of the vehicles have been restored but left to Nature.
It's an amazing town that few people know about.
Trees etc. / Fullspectrum Experiment:
I know, I should not post so many pictures at one time, this reduces the chance anyone looks at anything but the first. But ... well, I can't help it.
I carried the fullspectrum camera with me today, and stacked 3 filters on top of the Minolta 50-135/3.5 lens: A UV-IR Cut, a warming filter and an UltraContrast 0.5. This way I got RAWs with almost no blue, a lot of warm tones and muted greens. I did some digital post processing, but the basic „color grading“ was done while I took the photos, thus analog.
Possibly this is dumb artsy talk, but I find many of these have a certain „presence" that is hard to explain. The lens was used wide open, mostly.
Along this track that I walk so often right now there's little more than trees and what you see here, so I need to make something out of that. I think this little series showed me again, there is potential and birch trees are always the photographers best friends.
The Panasonic Lumix GX1 converted to Full-Spectrum by Spencers Camera & Photo [www.spencerscamera.com/fullspectrum.cfm] with the legacy Sigma 21-35mm f3.5-4.2 on a Prost Nikon to MFT adapter from eBay, the Spencers 665nm filter and a cheap sunshade in place.
The Sigma wide-angle is an awfully big lens for this small MFT. It was a fairly good lens when released, although it always had a problem with zoom-creep. By now it also has some dust inside and it shows the annoying center spot/glare when stopped down with IR. It's not always visible at f5.6 however. Probably because of the adapter, the focus is totally off, almost at the other end. Approximately 0.7m at wide and 1m zoomed equals infinity. It needs careful focusing from a tripod. Handheld shots are a gamble. Luckily the GX1 camera has some great focus assist features that make it possible to use the lens at all.
The adapter is more or less garbage. The lens mount is extremely loose, with proper stops missing. Not only has it rotational play of about 3-4mm, the lens to body can be wiggled sideways. I guess the mount on the GX1 is not the strongest either, not for that long of a lens anyway. It has worked okay and it let me use my old Nikon lenses, but I'm looking forward to some MFT lenses. I wonder if the expensive Novoflex adapters are tighter and maybe worth their high price?
The filters I got from Spencers as well. They claim they are the best filters around, but fail to describe them on their website. So far I can't tell if they are glass or optical acrylic. They are 1.1mm thick and have a very lightweight mount, the 77mm version weighs 19.71g compared to 25.87g of a Hoya ND8. They are glued into the mount, and both had a little glue creep onto the filter surface, which I managed to carefully scrape off without damaging the filter. On one filter the glass has become loose, but constitutes no problem so far. They are very difficult to keep clean, almost dust magnets, which makes me suspect they are off acrylic material, but I could be wrong and could it be the coating? They also seem to cover themselves with a slight haze, when stored away in their plastic packages. To see if the packaging gives off some vapors, I bought some filter stackers [great invention] and keep all my 77mm filters together now, between aluminum stacker caps. The filters work great otherwise. Unfortunately Spencers did not respond to my email questions after they sold me their products. I guess they are busy converting cameras.
