A few more from the Wolf Park, this time swapping out my Yellow 15 for a 720 nm filter. Leaning into the limits of f/5.6 to appreciate the caustics effect here.

Timber misjudges the catch, watching the treat sail by her left eye

Timber howling into the early evening sky

Visited the local Wolf Park conservation center over this past weekend with both IR and visible camera in tow

Gray wolf "Timber" catches venison treats thrown by her handler, showing off an impressive array of teeth.

A channel-swapped full-spectrum (minus yellow) photograph of timber, yawning from a log perch. Similar to how human skin looks in similar photos, her tongue takes on a yellow hue.

Timber eyes her handler intently for another treat, revealing her golden eyes.

Easy meals for the bird, fewer bugs for the bison. Aerochrome-inspired shots from this past weekend's visit to Kankakee Sands. Shot on a full spectrum digital camera with a yellow filter. #fullspectrum #infrared #wildlife #bison

An aerochrome-inspired digital color infrared image of a bison standing in a pink field. A small bird stands atop the bison. The bison licks the inside of its nose (gross!).

A panoramic crop of the same bison standing in a pink field. Now looking head-on to the camera. The bird remains posed atop the bison. A small pink tree stands on a distant hill.

A few more shots from a recent photo walk. All patterns captured in camera. #photography #invisible #bnw #abstract

A low contrast black and white image of a metal sundial sculpture, roughly shaped like an eagle's claw. One talon is coated in black dots.

A black and white photo of a concrete balustrade, coated in black dots. Differences in reflectivity give the appearance that a metal rail is now transparent.

A black and white photo of two benches, in front of the balustrade. Dots sweep across part of the image. The benches are rendered in white.

An abstract black and white closeup image of a mundane object, rendered almost unrecognizable, save for what structure is betrayed by black dots.

Happy accidents in double-exposing a roll of Fuji 400 during the #NoKings protest a few weeks ago #street #photography #bnw #film

A lone figure stands on a sandy Chicago beach past a pari of upturned boats. Abstract forms -- protesters marching and holding signs -- just begin to bleed into the image's top left corner

A black and white photo of the neighbor's very affectionate dog, squeezing through the fence to say hi, while looking both ghastly and world-wise. Signs, arms and faces appear to come out of the aether around the dog.

A (mostly) normal black and white photo of the No Kings protest. The courthouse in Lafayette, IN is framed between a US and Ukranian flag.

A clearly-double exposed photo of protesters holding signs with dour expressions, while a dog is groomed overhead, shoes and dog toys splayed across the floor.

Stumbled into a "Campus Clash" NERF battle last weekend while on a photo walk. Shot on Ilford HP5.

A black and white photo of three players running from a building's shadow into a brightly lit crossing. One is holding a cardboard shield.

A close-up action shot of a player mid-stride, their nerf blaster held in both hands.

A close up photo of three players in a tactical run towards opposing fire.

An unknowing bystander, coffee in hand, is caught in the conflict, surprised to see players holding NERF blasters around the corner

GIF'd the Artemis II crew's touchdown to the Pacific. Wow!

What the last five minutes before reentry look like aboard #Integrity (you can see the plasma build up in the last frame!)

Barrett Davis@barrettdavis· Apr 10

One photo every 15 seconds over the last 30 minutes before NASA's special coverage for #Artemis II started

Barrett Davis@barrettdavis· Apr 10

Watching the Earth slowly fill more and more of the frame as the #Artemis II crew gets ready for atmospheric reentry. Just amazing.

A screen capture of the Artemis II livestream taken a 16:48 Eastern time. The Integrity's rear thrusters can be seen just overlapping the half of the Earth in nighttime shadow.

A photo from the Artemis II livestream taken at 17:38 eastern time. One of Integrity's solar panels is now visible. the Earth appears slightly larger.

Some more photos with the 73-300 from I came across from 2022/2023 while migrating photos to my SSD

A shot from the highline north down an NYC avenue. Lens compression is extremely evident here, and only made possible by the long focal length.

A photo of a squirrel sheepishly holding onto a fencepost while appearing to look at the camera.

A couple sets up a red kite to fly, contrasting against aqua waters of the pacific in the background. Right before this one of them got down onto a knee, which prompted the snapping (turns out, just unlacing their shoes).

A photo looking south from Chicago's millennium park around sunset. The clouds in the background take on a cotton-candy appearance against green glass skyscrapers and red scaffolded elevators.

It was only after I started putting a lot of time into photography that I learned about the lens' reputation among Canon shooters... While it's no longer my preferred (or only) lens, I still quite like a lot of the photos I've taken with it

A soft, dreamy photo of a pine-laden spit out onto Lake Tahoe from the roadway several hundred feet above. Mountains are visible in the background dissolving into haze and puffy cloud.

A close up photo of a squirrel having a snack in early fall; green and yellow splotches can just be made out in an otherwise bokeh-ball erased background. Rain drops can also be seen in the image, caught mid-air.

A golden sunset photo of two silhouetted people walking by each other at the Albuquerque balloon festival.

A bright, airy photo of the Voss model on Purdue University's campus in early summer. The model is a fiery red/orange/yellow/white metal structure some 30 ft / 10 m in height meant to resemble the sun. It is flanked by green trees and a matte white cloudy sky overhead.

A walk through a local park with the familiar Canon EF 75-300 mm kit lens

A vibrant closely-cropped photo of yellow, cyan and blue waterslides.

A black and white photo of a duck in a pond. Ripples and mesh structures in teh water give the photo a sense of texture.

A black and white photo of two geese floating on steely pond water.

A photo of two kids on kit motorbikes. One's bike chain snapped, so the other is pushing them along with an extended foot.

Almost a year to the day when I pulled off to the side of a country road for this panorama. April showers have again flooded much of the surrounding farmland.

A black and white panoramic photo of a flooded field. A bare tree stands in the center of the field on its own patchy grass island.

Barrett Davis@barrettdavis· Mar 29

A high contrast black and white long exposure photo (or 1/3s exposure because the photographer didn't bring along an ND filter) of the tail end of the crowd walking across the pedestrian bridge. The courthouse can be seen in the background.

A black and white photo of a woman holding up a paper sign reading "F🖕🏿🖕🏼k Qualified Immunity". Streamers from a kite and their shadows cover the frame from left to right.

A man holds a shark kite up to the wind in the background. Two older protesters walk out frame to the right while reading the signs attached to the kite's line. Two younger protesters duck into frame from the left.

A high contrast black and white photo of a protester holding a small sign that reads "Draft Baron" while looking directly at camera. Their face is partially obscured in shadow from their sign and hat.

Barrett Davis@barrettdavis· Mar 29

A high contrast black and white photo from within the crowd of protesters. A man wearing a keffiyeh holds up a cardboard sign, partially obscuring his face in shadow, that reads "Their greed will kill us all". American flags fill the background.

A wider black and white shot of the protesters from above. A sea of signs fills the frame.

A black and white photo of a quieter moment from the protest. Concentric rings of people walk and sit around a child atop a circular bench who's holding up a sign that reads "Country before Cult".

A black and white photo of protesters walking back and forth up a bike / wheel-chair access ramp while holding signs.

A wider shot of the crowd walking towards WL from Lafayette along the pedestrian bridge. Two people in frog costumes cheer from the sides as people hold signs. The courthouse is visible in the background.

A panoramic crop of people holding cardboard anti-war signs: "N[peace sign for o] war" and "All children deserve peace" atop a Palestinian flag.

A woman holds a pasteboard sign that reads "Your war crimes don't mask your sex crimes". A person, wholly obscured by a frog costume, holds their hands up, looking like they're feigning shock.

No, this study did not assess the efficacy of autoclaves and it did not consider surgical tools. Instead, the authors placed polyethylene liners on an OR floor, then compared three different disinfecting solutions: CHG, povidone-iodine and 70% ethanol. (NB: I have no affiliation to the study)
