Depscribe,
Are you still experimenting with channel swapping only or was this image created using all available sliders?
Thanks,

Auto white balance in the Gimp, followed by channel swap. And of course some cropping.

depscribe,

Here are a couple images taken with the 720nm, with auto balance set in camera only, and PP in PS-el with 'hue/saturation and the other color management sliders. That was before learning to use channel swap. What do you think? It did create noise in the dark area.

They're interesting -- I think you'd be pleased by channel swapping the second one. Might give it a try.

I deleted the original already, it was all red in color. (because auto balance in camera setting). I will try again let see what will happen.

Depscribe,
This image was also done after your suggestion of a WB in the field and an AWB in post. After that it was just the channel mixer but with a dash of HSL, a smidgen of Levels and to top it off, Smart Photo Editor for a few droplets of color. This photo was taken on the grounds of the American Museum of Natural History in NYC. As always, your comments are most appreciated. (a little too much green remains which I have to work on)

Lovely -- I don't remember the AMNH having such vast grounds. Is the Museum Cafe still nearby? Great restaurant, and their death by chocolate is unsurpassed.

As you've discovered, you can do all kinds of things in post with IR, though I make a point of not getting carried away with it: AWB, channel swap, minor adjustments, that's it for me. Your mileage may vary.

Thanks, Depscribe,
Yes, the Café is still there along with some others now. The cuisine has been updated a bit but it has also been a while since I have eaten there. You could try the Café Storico in the Historical Society just across the street at 77th and CPW.
As always, thanks and the best,

I don't get to the city much nowadays, but I lived there for a lot of years. It has changed in ways I don't much like, alas. Good to know some good things remain.

Depscribe,
I sent you the following message the other day and I couldn't find it in the forum. Probably my mistake as usual.
The attached image was also made at the AMNH in front at 77th street. Again, WB in camera and Auto in post, channel mixer and some additional colors with additional software. (I will not be bombarding you with images every week - I promise)
I am becoming less sure of what it takes to win over the general population to the attractions of IR. For landscapes in particular, it may be simple yet powerful images illustrated with bright whites, deep blacks and ambers used judiciously. And no garish colors. The galleries at LifePixel are nice examples. I am still just experimenting and who knows where it will lead. I will be adding that 720nm filter to see how that works.
Thanks for looking and offering any advice.
Richard

Bombard! Bombard! By all means. We're all learning from each other, except those who know everything already. I have neither likelihood nor plan of ever joining that group.


Part of it is that people don't really know what they're looking at. Part of it is that digital photography is so easily manipulated that people figure it's just a stunt, which is part of why I don't like the garish colors, because you can do that kind of thing to just about any picture.

I have an ancient (well, 2005, so ancient by digital camera standards) Canon SD-400. It's a nice little pocket camera. One of its peculiar "features" is the ability to swap one color for another. This means that in somer respects swapping green for yellow will produce something resembling 590nm infrared. No idea why Canon thought this was worth doing, and I never used it, even to try it out. But with that kind of stuff being placed in consumer cameras, a certain amount of yawning will come from all but our most dramatic IR images, I think. (And even then they'll suppose it was trick manipulation in post.)

So we're left to learn and experiment and enjoy, and let those who'll listen in on the secret.

Thank you Depscribe,
As I was browsing the LifePixel galleries today I was struck by the combination of both amber and white foliage. How does one do that? Layer masks or what?
Thanks,

Part of it is white balance, part of it is the filter used, and part of it is hue adjustment in post. It's a lot easier to manipulate pictures than one might suppose. I've been fixing up various infrared pictures for a number of years now, and I'll let you know the next time I use a layer -- which will be the first time I use a layer.

Here's an instructive video on the subject: https://www.youtube.com/watch?v=eYFdA7c48Yc
(by the way, you'll notice that the guy's lens has an unpleasant hot spot -- most lenses do, to some extent)

Thanks for the reference. However, there was no mention of creating different colors among identical plants/trees/grasses. This is a really helpful skill and I am anxious to try it. I was looking at the Lifepixel galleries today and some of the nicest images contained both amber/yellow and white foliage.
Let me know how to go about this whenever you can and I will continue to scout locations here in Manhattan (for starters) that could be really beautiful.
In the meanwhile, happy channel swapping and be well.
Richard

Here's a Polyphemus moth I happened upon before church as I strolled along in front of the Court Diner in Athens, Ohio. Shot in 590nm, because that's the body I had with me, and with the 14mm Fujinon, because that's the lens I had with me. My feet.
