Infrared (IR) Image gallery

Finally used my R72 Hoya today.

Really? I suppose it's a good thing I didn't send them an email yet, because if the Hoya does it, it seems like most would...

Like I said, the one I got has NO color variation. I'll post an example below, but I don't see any way these could have any variation, even with channel swapping. It's acting a lot more like a weakish red-tinted ND filter, really.

I tried over and under exposing too. You're right it is like a Red ND filter. I had to apply the IR Black & White filter with Silver Efex. Everything else was too dark or too bright...

Well, now I'm just confused. All the other tutorials I saw had COMPLETELY different results straight out of camera. It's like it's letting too much color in - like I said, not even cooling the WB will bring it to something usable (look at the yellows...).

My 850nm filter gives this SOOC, and although this is an underexposed shot, it's obviously more usable.

Oddly enough, I did shoot this same water fall with my ND 8 because I wanted to use a slow shutter speed to catch the flow of the water. The IR filter did act as a IR filter I suppose because the ND photo looks more normal as a straight BW but looks blown out if I use a BW IR filter on it. Fun stuff!!!

I wonder if anyone with some 720nm experience will happen to pass through here today and shed some knowledge?

As artemisn and I have stated the 72 Hoya gives off a disgustingly RED look. Crying, BEGGING to be converted to B & W.

It's the green leafy plants that give the IR photos their glitz isn't it? I think I have that right.

Just us in here, my friend, both of those posts were from me.

Thanks for the SOOC shot though, I was about to ask if you had it! It does look like yours is more red and less orange than mine - although looking back at my test shots it seems the orange only really comes out when overexposing - and from what I've read you're supposed to overexpose IR by just a tiny bit.

This is quite honestly making zero sense to me. Especially since I expected to get a little something like this : http://www.flickr.com …001589494/in/ph​otostream/

(That guy also has test shots from IR filters before/after that one if you want to take a look. I think he's from POTN also...)

And aye! Plants/anything with chlorophyll are supposed to be white in IR, which is why I read to shoot the grass and use it for white balance. But it can't counterbalance all the red! *frustration*

Here's a 20 second exposure. I also did a 30 second exposure but that was too bright.

It looks like we'll have to find someone else on here with a 720nm and get their exact processing - like I said, I don't see how we can get anything two-toned from these results. Channel mixing just changes it from a really red photo to a really blue photo, which isn't exactly useful. B&W is a bit odd to work with on it too.

In a lot of mine, it seems converting to B&W makes it look like an ordinary B&W photo..

I think if you took a regular shot at this same location and converted it to B & W you'd see a difference in the trees in the background there. There is definitely some IR action going on there. As you mentioned, it's a tad bit under exposed.

Heh, I just had to change the color of my keyboard light from Red to Blue... All of this damn red is REALLY hurting my eyes!!!

What magical keyboard is this? I'm hellbent on getting one of the IBM clicky keyboards whenever I get another desktop, but I must admit I'm a bit curious!

It's a Saitek brand. I like it. It has Blue, Red, & Pink (I wish it had Green). The keys light up and there are lights on the left and right. I was looking for a USB keyboard a few years ago and found this one. It even has a brightness dial.

Oooh, they make nice stuff. That brightness dial sounds like some thoughtful genius - I hate how some technology doesn't have an off switch for the LEDs - looking like you live in a sci-fi is cool until you have to sleep in the same room.
