Embracing Flare and Distortion
Berkley-Dighton Bridge
Berkley, Massachusetts
Shot with the 830 nm Singh-Ray "I-Ray" infrared (IR) filter. I'm very interested in IR photography, and couldn't resist picking up this filter a while back when Singh-Ray had a sale. This is my only reasonable shot with it so far. For me, it's got a pretty serious limitation (on the D750 at least); namely, I estimate it behaves like a 20-stop ND filter, which means you need serious light, a large aperture, and/or a (relatively) high ISO for a realistic exposure time. (I normally would have shot this at around or above f/11 and ISO 100, but the exposure time would have been over an hour!)
This filter does not pass light with wavelengths shorter than 830 nm (the visible spectrum ranges from about 400 to 700 nm), and is considered a "deep B&W" IR filter. I hope at some point to acquire another body and convert it to IR by removing the internal hot mirror filter that blocks IR, allowing the camera to be used "normally" (once calibrated). There are several internal filter replacement options; I'm intrigued by the "Super Color" IR option offered by Life Pixel, which has a cut-off wavelength of 590 nm, allowing some visible light to pass, and also allowing filters with higher cut-off wavelengths to be used, like this 830 nm filter. See this article by Jason Odell for motivation.
As for the title, I had a tough time finding a composition I liked that didn't suffer from the horrible distortion that causes the nearest street lamp to look like it's about to topple over. And after much time futzing around, the sun moved into flare-inducing territory over the course of the exposure. I kind of liked it's look though, as it seemed to fit with the IR effect.
Lastly, I probably won't be on Flickr regularly around the holidays, so I hope you all have safe travels, and wonderful times with family and friends. Cheers! -Mike
