"Capturing Infrared"

More experiments: the Hoya 25A filter cuts around 590nm. Results are completely red in-camera so it is harder to compose, focus, and meter. It's even easier to blow highlights, so underexposing is usually necessary. Most other colors are gone but with a custom WB and Foveon Classic Blue color, I found it possible to get blue skies back. Combining this with a CPL should result in dark blue skies.

Graham, I personally am liking the rendering you're getting with the Green filtration -- it seems to generate just enough separation for both red and yellow greens and adds some depth and texture I find appealing.

Thanks, Jack! I agree, the results I'm getting with the X1 filter are a bit better than without. Also, it's hard to appreciate here but when I pixel-peep, the sharpness is better as well. I think the filter removes some chromatic separation in the shorter wavelength colors.

Graham,

I took the liberty of grabbing one of your "tonal" IR color images and converting it to B&W. I have to say it generated a very pleasing mono IR rendition. You may be onto something really good :thumbup:

Thanks, Jack! Which image did you work with? Feel free to post if you would like.

I must admit I'm a sucker for color, so I don't shoot or process images in B&W often enough. I will take it as a challenge to do some more with this camera though :thumbs:

Until then, I have a few more color images to share that I've already processed :cool:

Here's one that I liked. I just grabbed your jpeg from above and dropped it into CS. I added a B&W layer, hit "auto" then tweaked the red, yellow and cyan sliders for the general look, then did a curve to boost the bottom end a bit. I like the etherial quality to them, enough so I may need to reinvestigate a 2-spectrum conversion ;)
