The first batch were from a Canon 5D that Life Pixel had converted to 665nm IR, and I purchased it off ebay. After about 18 months I sent in my 5DmkII for the same 665nm conversion. It is much easier to get critical focus on the 5dmkII due to live view, and I also can see exposure in real time to get the highlights correct. These are from the new conversion to a camera I bought in 2009.

Again just super looking images Jim!
I really like the wavelength used to make the leaves standout so great and the stream/ water so dark!

Fine work Jim!

Dan, there is bit of a learning curve to IR.

#1-Autofocus is usually off - even if calibrated. Some services will calibrate for a particular lens. Therefore, manual focus is really the best way to go. Some MF lenses have a red dot near infinity focus to approximate where infinity is in the infrared spectrum. With my 5D I had to chimp for focus, and exposure, but once you have it nailed it works well. Otherwise, I would get a camera that has excellent live view with almost no lag to the rear screen

#2-some lenses are not good at IR. They generate "hot shots" usually in the middle of the frame, and worsen as you stop down. Almost all my Nikkor lenses work great at any f-stop, but I do have one that has stellar performance in the visible light spectrum, but makes hot spots in IR. A separate F-ring is a big plus for me.

#3-Generating a white balance profile is done a number of ways. I initially followed Robert Reiser's tutorial using Adobe's free DNG profile editor. There are some really wacky colors in IR, but I prefer the black and white profiles I created. However, you can approximate a 830nm profile easily in Photoshop. ctrl + U and desaturate completely. Find the D-max and D-min (brightest highlight, darkest shadow). Then ctrl + M click highlight eye dropper on D-min, repeat clicking the shadow eyedropper on D-max. If it removes too many gray levels use the fade adjustment.

Super composition Joe. Along with the church! I must start experimenting with IR.

Anyone have a suggestion for a novice?
Thanks!

Thanks for all the info Jim! Yes I realized it was lot more "involved" than just a filter. You, and others, make it look so easy IMHO..and I know it isn't.
My post processing skils are minimal at best but Adobe, and your advice, make it a bit more understandable Ps wise!
THANKS!
Dan

To everyone who posted images, they are great, well done. Now I am interested in trying this type of photography
so I will need and help from you people to get me started. I will be using my Z6 and I would need to buy a filter, so which make and what nm? And of course how to process the images, what software etc?
So if someone could give me advice on the above questions it will be much appreciated.
Regards Derek

From a recent trip to France, all on a Ricoh GR2 converted to 720nm.
The camera is currently being converted again, this time to 850nm. I'm done with color infrared!

The shots from France have a nice feel to them. I assume you're adding a little glow in post, which I haven't tried yet.

I really debated between 720nm and 850nm when having my camera converted. My only plan was/is to shoot B&W, so I almost went 850. However, I kept reading how 720 was more flexible and 850 would be higher contrast (which I could always add in post). I ultimately went with 720nm. The useful information on the web is limited, and even the videos by the companies that do conversions seem to focus on color IR, which doesn't interest me. YouTube influencers are next to worthless for real info.

Good luck with the re-conversion. I'm sure it will work out great for you.

Thanks, Doug.
Yes, I add halation, grain and contrast. It's sometimes tough to balance it all, the highlights can get quickly blown out.
Having a 720 camera is indeed the most versatile option. The colors aren't garish like at lower wavelengths and the B&Ws have excellent contrast.
My first IR camera was 850nm, and it made great images. I just didn't have the processing experience I do now, and I know that B&W is my preferred look for infrared.
I'm always after the Kodak HIE look, so figuring out how to do it well is half the fun.
