Infrared River Zoo - Inky Depths

Because the infrared camera is only sensitive to frequencies that we can’t see, the fact that water absorbs longer wavelength light makes it nearly black. I am surprised, however, that feathers reflect infrared very similarly to visual wavelengths. I expected more of a difference there.

The effects are quite surprising at times. What camera are you using for these? I though most cameras had IR-blocking filters...

I picked up a modified Nikon J4 on eBay. I wanted to do a cheaper experiment to see if it was worth modifying a d800 or d810.

The answer is, I like the effect, but I think I want the wider range so false colours are picked up too. I can always drop it down to look like this, but I'd still get to do false colour shots.

The problem is that I really do want a full frame body to convert and the jump between the d600 and d700 to d800 is significant, but I don't want it enough to drop $3k to do it.

So I'll probably just shoot the J4 here and there until used d800s drop to something more reasonable.

Right. Some of the astrophotography folk are into modding DSLRs, but it can be a significant outlay.
