This pic is exactly the type I hope to start with.
This thread has worked well for me. I bought the camera for conversion well over a Year ago and this finally got me in gear. Camera is converted and in mail on way back to me.
So Thanks!

Can't wait to see your pictures!

Delivery got canceled, so I got to make a short trip to the sprawling metropolis that is Amesville, Ohio, and made a couple of pictures there.


Were all these pictures taken with 720nm filter?

Well, with a camera converted to 720nm. And yeah, it's kind of weird how the colors vary with the direction relative to the sun -- they were taken within a couple minutes of each other. Which is why for anything important it's good to keep getting new white balances. I took only one for the set.

I got these two with 720nm and minute apart, the sky are little bit different.

I did enhance the color a little bit.

Very nice pictures.

(I think we should remember that we're doing experimental stuff, using equipment that wasn't designed to do what we're doing with it!)

I would expect this. In the top image, the exposure is being determined by the tree leaves. In the second, the exposure is based on the train. The results are going to be different -- unless you are manually controlling the exposure.

No, I can not manually control the exposure, as you knew that I mentioned before, I only have a full spectrum converted P&S camera to start my IR shooting, but so far I am very happy for the result, and getting more experience on the PP.
I just came home from the park and took some more with different filter.

The fist one was using the Red 25A (I still waiting for the 680nm).
The second was using the 720nm.

It's infrared season in North America, and looking around I found little enthusiast discussion, so I thought it might be good to start one.

I've been shooting with a Kolari-converted 720nm Fuji X-E2. Oddly, I've not found the Fuji lens that handles IR well. Most produce hotspots or, at least, a central color shift similar to vignetting and a real pain to repair. Even more oddly, I've found that my old manual-focus Nikkors, with an adapter of course, seem to work just fine in infrared. There's a good chance that in the coming weeks I'll have my original X100 converted to 590nm and dedicate the X-E1 to black-and-white, which is to me purer infrared anyway.

I shoot JPEGS, most of them in color, and bring them in to the GIMP 2.10.10 for auto white balance, channel swap, hue and level adjustment and -- a wonderful addition to GIMP 2.10.x -- toning down highlights and pulling details out of the mud with its new sliders. Here's one I shot and processed a few minutes ago that I like.

Anybody else shooting infrared in the spring? Any special techniques? Any treatment for hotspot issues?

I just got a newer camera converted to IR - a Nikon D2X to replace my D70s, so I have a big 12 megapixels now instead of 6. Again I got the Lifepixel enhanced color filter (665 nm). These are some of the first images from it:

Were these images just pp only with channel swap, no further color management? Thy are colorful. I don't know my ordered 680nm will be similar to this.

Very nice. You can play around a little with the other controls -- hue and saturation, levels, and my personal facorite highlights and shadows -- and make the picture into exactly as you want it to be. (I don't know, for instance, if you would like to lighten the building in the corner, but you can without changing the rest of the image much.)

You did the saturation stuff in post, right?

Yes. I use a Photoshop action you can get at https://khromagery.com/2011/07/04/false-colour-infrared-photoshop-action-on-photoshop-exchange/ It does the channel swap and adds several adjustment layers, including a Hue/Saturation layer which you can play with. I move the master saturation slider about half way to get it started, and then I go to each individual color slider. I first move each color slider to the max, which immediately identifies where that color appears in the image, and then back it off to where I want it. After I have adjusted each color, I evaluate the overall image and then readjust if necessary. I often add a curves layer also to adjust contrast and tweak overall color balance. Sometimes I also use a Hue/Satuation or curves layer to a selection to manipulate selected parts of the image. Some of the images also use a flash fill, which yields different colors in IR than sunlight.

Correcting my typing mistake, the filter using should be changed around.

Camera showed up today, unfortunately the weather was uncooperative. in-between rain clouds i shot these.

I have a lot to learn but I can see that I'm going to enjoy it.
btw these are SOOC JPEGs.

Edit: I can see I need to learn how to judge exposures a lot better.

There's a lot of cool stuff you can do in post with those.

Rainy weather and gray skies are less fun for infrared, though I did a little experiment today, shooting across the holler in the middle of a rainstorm. What surprised me was how bright the woods across the valley were -- almost as bright as on a sunny day. So the IR was sneaking through, it seems. (Looks a little like a medieval Japanese wall hanging, I think, in delicacy and coloration.



And here's a bog standard IR picture; I went goofy with chroma.
