How about some infrared images

[polyglot]

This seems like a great thread to post an "I'm on the IR learning curve" question. For those who live in parts of the country where leaves change color in the fall, am I correct in assuming that as the leaves lose their green color the IR effect diminishes? A few of the leaves here are just beginning to turn yellow and red, but most are still green, although the more vibrant green of summer is fading.

Some wooden material without chlorophyll (e.g. fenceposts) also shows a pretty strong IR glow while some (bark of some species) doesn't. Autumn-leaf effects I assume would also be species-dependent. e.g. some evergreens come out dark and some come out bright.

Heads up to anyone who's interested, there are 4 more of these available on the 'bay right now, for $9.99 each. That's 120 8x10s and 240 4x5s in Konica infrared for $9.99 + shipping. 170922380334

And yes, I bought 2 more before posting this.

Wow, I really want one but they say "SHIPPING TO US AND CANADA ONLY! NO EXCEPTIONS!" in huge lettering. Is there anyone in the USA who could re-ship it to me?

Thanks for the heads up, I got the fourth one!

Konica infrared, 8x10, IR760 filter, exposure was 45s or 1 minute. Don't remember what lens. I won't be able to get details on leaves unless I get faster lenses, use a red filter only, and shoot in midsummer.

Technidol will help bring out the details. Konica 750 is very similar to techpan in this respect, even uses the same developing time. I noticed better speed using it, maybe about a stop gain.

Really? I'm using dilute HC-110 as a way of managing contrast, which is rather unpleasant with this film. I was toying with trying Pyro, until I read the label on the box they sent me (I develop most of my stuff in the kitchen sink). I'll start looking for that, because I'm not really happy with the way the HC-110 is working out.


Detail isn't that bad still, with the HC-110. My problem is that there simply aren't any days with no wind whatsoever, and all my exposures are more than 30 seconds. Here's a 1200dpi crop of the scan (cheap, worn-out flatbed):

Yeah the amount of Technidol left in the world is limited so we need to figure out a good replacement formula for it. I'm told it's a POTA developer, forgot what the acronyms stand for but theres a few POTA recipes out there. If anyone knows what the equivalent recipe for Technidol is it would be nice to know how to homebrew it.

HC-110 is terrible for film speed, just like Rodinal. While I've never used Technidol or Tech-Pan, I can recommend Xtol if you want better speed without compromising the grain.
