First IR Photo - a Rainbow

...processed with my newly converted Nikon D7100!!!! :)

I had it converted to 590nm with Lifepixel. And they did an awesome job. I hemmed and hawed for a long time on what camera I wanted to convert, and also I toyed with a Full Spectrum conversion since I do Astro. But in the end I decided to just get one of my old cameras converted to actual IR, and the 590nm wavelength since I like that look the most.

I also sent in the Nikon 18-200mm lens which I had used most with that camera, and they calibrated it so I could focus through the optical viewfinder as I still am not much for using Liveview. Some year perhaps, but I still like the old Optical Viewfinder the best.

Thanks so much to @Amy Nelson she has held my hand throughout the whole process. Giving encouragement and guidance along the way. And especially giving me inspiration with the awesome IR images she posts here. I hope more of you are inspired and get a spare camera converted too.

My first experience with it, is it's amazingly simple to use. You don't even have to think about it with the Optical Viewfinder. And processing was just as simple and easy. I almost did nothing to process this. Most of you will remember I had been using an external filter, a 720nm that I would use to play with IR. Well the filter was a 10 stop at least and it caused so much issue because all of my exposures usually ranged from 5 to 30 seconds long. Even a slight breeze messed everything up, and if it was getting dark at all, all of a sudden I was shooting at ISO 6400 at 30 seconds and it looked lousy. With the conversion, I was shooting the D7100 like normal and the same basic exposure times. I was shooting handheld at sunset and it was great.

Anyway, I can't tell you how much fun I had with the 30 mins I got to use it tonight. And like I said, processing was so simple it was a joy. With using a 720nm filter the look wasn't exactly what I wanted, so to get it right I was jumping through all sorts of hoops, it was a pain...

So this first one it had just gotten delivered and I brought it with me to the grocery store in case I saw something along the way. It had been raining and then the sun came out and this rainbow appeared. I am in the middle of the city mind you, but I found a spot with a few trees and grabbed a few shots before the Rainbow disappeared. Since the camera sees in IR, the Rainbow is quite different. It's still visible, but quite a bit dimmer.

This one if you look close is a little soft on the edges. It was a user malfunction on my part, as I was quickly running through various f stops as I was shooting so I could double check if there is any hotspots in the camera/lens combo. So when I went to start up the initial calibration I just grabbed any of the shots, because my idea was to use it for the initial calibration, not for processing this time. But once I got started, I couldn't stop.... Then I looked at the aperture was at f4. So hence slightly soft edges. I will check the other photos tomorrow and I am guessing that the f5.6 and f8 will be much sharper across the image.

Anyway, hopefully you can tell I am excited! :) All comments on this new image and camera setup is great appreciated.

Great starting point - nice to hear your experience with this too. Interesting to see the rainbow in IR as it is far less visible than what we usually see in the normal visible light range.

Glad you are finding so much joy in this endeavor Jim. Good first IR. At first I thought the rainbow was part of a vapor trail but now I see it and it appears to joining a wisp of cloud that coincide with the rainbow arch.

Thanks Alan! Yeah, I found it quite interesting to see how the rainbow would turn out.

Thank you Ben. There is still some faint color in the rainbow, so that's pretty cool.

Jim,

Love this, and so cool to see a rainbow imaged in IR! I have a 590 external filter I can put on my full spectrum modded T2i. I need to play with it more. I am curious though, did you not do any kind of a channel swap for this? I thought that was required to get this type of look even at the bandpass you are working at that combines some of the natural color bandpass into the IR...

Thanks Mike, I am glad you like it and yes, screw on that 590nm filter and get going! :)

Yes, I channel swapped it.

Doing super good right out of the gate. I think it would be easier to start with an image like your rose that you working on to get dialed into the different facets of IR. A landscape has such a broad scene with so many different points of interest. But I do 👏👏👏 you on your first post.

A very fine result for sure. I will have to try some IR again - I just uncovered my 580 filter that had gone missing for a while :)

Thank you so much Amy! Of course I can't do it the easy way. :)
