Near-Infrared Photography

Been experimenting with NIR-photography for the last couple months with my Nikon D3000 using a Hoya 720nm pass filter.

Takes some time to get the focus and exposure times right as the camera is unmodified, but the results tend to look pretty spectacular!

Photos are taken with varying exposure times (between 13-30"), channels swapped and processed in Gimp.

They look quite nice.

How do you get the sky blue, swap channels etc?

Nice work. With infrared some lens develop hot spots and reflections and others don't. I think it can be a matter of trial and error. You seem to be getting some lens reflections there. If you have another lens it might be worth trying that out as well.

I did some with a Fuji XE1 and the standard 18-55 zoom gave a hot spot but the 35mm F1.4 did not.

Greg.

Thank you for the kind words.

Yes, the hot spots and reflections are a pain, though I'm stuck with the standard 18-55mm lens for the time being. Probably use better framing and cropping out the hot spot in future photos.

In regards to channel swapping in GIMP, I've attached a photo that hopefully answers the question.

They look great I converted my Canon 20D to 665nm NIR last month and got some great photos. Modding the camera make framing and focusing so much easier.

I love the sureal look you can produce, and the channel swap really gives it a unique look!

I was getting some hot spots with my standard lenses also. There was a website that listed which ones performed better than others for NIR. Keep it up

Glad I could help Kevin.

Thanks Eric. I'll definitely look into that website and different lenses, gotta get rid of that hotspot.
