{IR}L
I attend estate sales not because I need anything, but for the thrill of the treasure hunt. But nothing prepared me for what I stumbled across on a heavily discounted day. It was day three of the sale, which meant 75% off everything left in the house. It was a sweltering July morning in Texas, and a dozen of us were idling in our cars with the A/C blasting, playing a game of chicken. Be cool, stay in the car, I thought to myself, watching the rearview mirror. But of course, someone broke rank, stepped out onto the sizzling asphalt, and forced the rest of us out into the heat. Now, I was ninth in line, at least we only had 10 minutes to go.
When the doors opened, I beelined straight for the electronics room. You don't expect top-of-the-line gear on day three—the 3D printers and spools of filament were long gone. But tucked away on the floor was a familiar black canvas bag. I unclipped it, expecting to find a basic, run-of-the-mill entry level Canon DSLR. I picked up the camera body. It was as I suspected…basic. It had no lens attached, nor were there any to speak of, and the battery was completely dead. But as I turned it over in my hands, two letters scrawled across the body in silver metallic Sharpie caught my eye: IR.
My heart skipped a beat. Could this be a full-spectrum conversion?
Factory digital cameras come equipped with an internal filter that blocks infrared and ultraviolet light, keeping images true to what the human eye sees. But a niche subculture of photographers pay to have that filter removed, turning the sensor into a full-spectrum light collector. The sticker price was $200, but with the 75% discount, it was fifty bucks. A gamble for a camera that wouldn't even turn on, but I rolled the dice.
Two agonizing days later, after waiting on our Overlords Amazon to deliver a charger and spare batteries, I inserted the new battery and held my breath, it worked *breath. If nothing else I had a camera that turned on, but no lens, or did I? In the bottom of the bag I’d discovered a Helga pin hole lens. A pinhole lens on a full-spectrum digital body is an absolute wild card, there’s no glass, no focus controls, just raw light passing through a microscopic aperture (roughly f/133) directly onto an unfiltered sensor.
I stepped outside, held my breath again, and hit the shutter.
The results were immediate and…pink…and blurry. Because this is a full-spectrum camera EVERYTHING makes it through. The camera works, let’s get a lens…and a filter.
Back to the waiting game.
eBay isn’t Amazon, so it took a week for the lens to arrive. It was an inexpensive kit lens, but it worked. After threading on the 720nm filter, I once again trooped outside. Deep breath…it worked! The resulting images feel like stepping into a parallel dimension. Foliage glows a stark, ghostly white against sepia skies, rendering everyday landscapes completely liminal and surreal.
A few weeks later, as I flipped through my latest set of shots, I found myself wondering about the man who owned it before me. Why had he converted it? I went back through the rest of the camera gear I’d picked up at the house. Tucked into a side pouch were a series of extremely dense neutral-density filters, the kind used specifically for solar photography. I went straight to the estate sale coordinator's preview photos, I needed more information, what equipment was there before? I spotted what I had missed on the first two days of the sale: a heavy-duty tracking mount designed for deep-sky astrophotography.
He wasn't just taking surreal landscape photos; he was pointing this converted sensor toward the stars, capturing light from distant suns. He wouldn’t have used the ND filters on these, just our sun, but I wondered what showed up in the night sky that I was missing because I could only see the visible spectrum?
I held the camera body for a moment, looking at the faded silver Sharpie marks, holding the tool he used to peer into invisible spectrums, I wished I’d had the chance to sit down and have a conversation with him. I think we would have had a lot to talk about.
