Captured with IR-converted Nikon D70s.

Gorgeous IR. Love the shapes also.

That's just awesome! Nice image!

Nice shot, Jeff. You're really getting this technique down.

That's beautiful.

It's very cool, but what are we actually looking at? Is it a composite of a "normal" shot and an IR shot? Or, is there a way to capture both "normal" colors and IR effects in a single shot?

Obviously, I don't know much about IR, but it can be fascinating to look at, so I'd like to understand it better.

RGB Pro

Yeah!
I dig it.

Superb job !

Howdy Jeff,

What a beautiful image I am really loving the colors you're getting out of the enhanced filter, that is sure something to think about if I get another one modded.

Very nice composition, just a super image.

Good question. It was captured with a "enhanced color" IR converted Nikon D70s. There's some channel swapping of red and blue here. The sky goes from red to blue. The blue sculpture turns to red. And the green trees turn white (because they were the anchor for the white balance setting). But then, too, there's a portion of the sculpture that I decided not to apply that swapping. So you're looking at a mostly channel-swapped image. Or did I completely confuse you?

Thanks for the kind words!

Niiiiice! I really like the wierd colours

I see! Kind of like selective colour conversion in IR.

Do you have a link to the specs of the filter you selected? I'm guessing it lets in just a touch more toward the visible red, something like a 680 nm cut-off?

Go to LifePixel and look at their different options. "Color enhanced" gives you the most data to deal with in post processing.

Thanks, I was hoping you'd point to Lifepixel
The colour enhanced is an IR-pass with the cut-off at 665 nm, I've been shooting through an R72, which has the cut-off at 720 nm.

I have the clear glass option in the camera from the same company, so I can still ask

Ummm.... possibly. If it swaps red and blue, how does the sky remain blue? When you say you "decided not to apply that swapping", does that mean this is a postprocessing step? All of it? Some of it? Am I asking too many questions?

IR-modified cameras produce red skies, hence swapping the channels makes it blue again. Channel mixing is done in post.

Yes. And I selectively applied the channel mixing so as to retain the red in the center artifact.
