I bought this NEX-7 from Cindy Flood about 5 years ago and am just really messing around with it now. I'll try to get a few up in the following days/weeks. I am VERY new to IR (655nm) so any suggestions and advice would be greatly appreciated. I am trying to get nice blue skies, but it is proving a challenge. With Canon 24-70 f4L.

Joel, I would take photo into PS. Convert to Profile > lab color. Then CTRL-M to bring up a curves adjustment. Under channel, pick b. Move the left side of the curve in. You can play around with curves in lab and see if you want blue brighter or lighter. Then Convert to profile back to your regular editing profile (mine is prophoto). You might need to do a hue/sat adjustment now and just work on the blue channel. ....see if that gets you any closer to what you want.
The lab color space is very powerful in bringing out the colors.

Your photo is very nice. I don't find the sky objectionable.
I went back a processed a photo taken with your camera.park-1.jpg I think you have to get used to the fact that these are false colors and don't always come out as you expect (but that is the fun of it.) After using the LR camera profile (that I gave you) and taking it into PS and swapping the channels, try the LAB adjustment. Then do hue/saturation adjustments. If you are still not where you want to be, just play with it. Maybe others can add some tips.

Re: "Capturing Infrared with Sigma 16/1.4 with Sony Axxx?

Hello, I am currently very interested to "upgrade" my Supercolor converted A6000. This lens seems to be really sharp at a great price. I've searching through the web for info including Lifepixel and Kolari hotspot databases but no luck yet.
Thanks for your responses and comments

Test images taken with the Kolari IRChrome filter on the Canon EOS R FS. I expected OOC images with predominantly red vegetation hue, but they were mostly orange. Requires a bit of HSL adjustment to get anywhere near the adverised look. I created a custom in camera white balance using shot of an 18% gray card.

One more with the Canon EOS R (FS) and Kolari IRChrome filter. Custom white balance in camera using 18% gray card. These are SOOC colors with no hue adjustments. Focus was on the robin.

Although there is very little naturally occurring infrared light available at night, there is often a surprising amount of infrared light from man-made sources bouncing around.

As a result, it turns out that, to my surprise, taking IR photos at night is absolutely possible, often with very interesting results.

Such as these, all of which were taken using Hoya R72 filters screwed onto various C/Y lenses in combination with a DIY-converted full-spectrum Samsung NX500 mounted on one of my FrankenKameras:







Of course, I also enjoy doing IR photography during the daytime as well, especially of the handheld variety as I walk around with my dog at midday, with its harsh, Arizona summer sunshine. All of these photos were taken using a Hoya R72 filter screwed onto a Contax N 24-85 zoom in combination with the same DIY-converted NX500 I used for the nighttime photos, then subsequently converted to B&W during post-processing:







P.S.: To my surprise, almost without exception, all of my vintage C/Y lenses, as well as my Contax N lenses, work very, very well for IR photography in combination with my modified NX500 and a Hoya R72 filter. I can't speak to whether they will work equally as well when used with other camera bodies or different IR filters or focused at different distances or using apertures other than f5.6 and f8 (my usual choices), but they're priced right, not to mention compact and lightweight ... a win-win all around! :D

And as a final bonus, here's a five-panel pano I took handheld using the above CN 24-85/NX500 combo and then stitched together using Photomerge in Photoshop CS6:
