Infrared Photos of Clouds and Contrails

[Mick West]

Infrared gives great contrast to clouds and contrails, bringing out detail that might be missed. Especially as they fade away. So I thought it might be nice to have a thread to share these types of photos. Feel free to add.

Here's one with an iPhone photo for comparison. Camera originals

Beautiful photos. Thanks. Every time I see IR scenery, it reminds me of snowscapes.

Try it with a polarizer.

Try it with a polarizer.

Interesting, you do get even more contrast. Not a lot of clouds in the sky right this moment.

Also, with the polarizer on the autofocus stopped working. I switched to manual, and this one photo turned out super sharp. I wonder if the autofocus is a bit off with the IR. Experiments needed.

thats what they are (mostley) used for in photography

I wonder if the autofocus is a bit off with the IR

I can confirm this behaviour for my IR-modified Exilim. not always but most of the time (I think the Contrast-detection autofocus doesnt work well with the slightly "blurry" IR)

Earlier today. Thunderstorms approaching

Nice shots! Especially the panorama. What wavelength filter?

720nm. I need to get a higher wavelength filter.


Just ordered this set. Only $40!

Cool. I have a 650, 720, 850 and 950. I get some lens hot spots with my 850 and 950 cos my lens is cheap.

I got my longer filters today. There's a strong difference between the 720nm and the 950nm, which lets through less light (obviously).

The 950 gives more contrast between sky and vegetation, but less contrast within vegetation, so the trees look more white and washed out.

720 left, 950 right, drag to compare.

 

[Mick West]

950nm really needs a tripod. It gets a slightly higher contrast sky, but often ends up a bit blurry.


I switched to 760nm, which seems like a reasonable compromise.


Really though, I've not sure seen a huge improved in close-ups of planes leaving contrails. Maybe a bit clearer, but it's hard to get an exact comparison.

Mt Shasta from 32 miles away. 760nm

Check out how well it cuts through the haze. The color photo is an iPhone, so low resolution, but the haze difference is obvious. See especially the low hill in the foreground compared to the mountain.

I apologize in advance for the shaky hand held video. Thought folks may be interested in the difference between IR and normal spectrum video.

I was playing with filters and camera setting on a cross country flight. The combination of IR filter with high contrast black and white worked the best.
