In the Field

Full STOP - Threat Sensed. Khutzeymateen Grizzly Sanctuary, northern BC coast, Canada. May 31, 2013.

This was a moment I'll remember for a long time. We had been watching this female grizzly and her two cubs foraging on the edge of a channel in the Khutzeymateen estuary when the three of them apparently decided the grass was greener (and tastier) on the other side of the channel. At the time the tide was rising and was approaching its highest point, and had functionally stopped the flow of the river, producing calm waters. The three bears chose to swim a route that brought them quite close to our boat. Just as they were passing us both mom and the cub swimming beside her stopped swimming and went into "all sensors deployed" mode - with their erect ears, focused eyes, and collective noses all pointing at the distant shore. When I captured this shot the bears had pretty much stopped their forward motion, but the incoming tidal current still produced a small standing wave in front of their noses and ripples along the sides of their faces. After I had captured a few swimming-in-profile shots I looked along the bears eye-lines and, sure enough, saw another bear walking in our direction, though at the time it was hundreds of meters away (but obviously close enough to cause these two bears some concern).

I captured this shot with a fairly long telephoto lens - a 600mm f4. Like with any shot, and especially when hand-holding a big lens from an unstable surface, I had to try to "optimize" this shot by balancing the variables of shutter speed, aperture, and ISO. The subjects were quite close to me and, even though they were close together, I knew it was absolutely impossible to render both subjects sharply (regardless of the aperture I chose). So I stopped down enough to get Ma totally in focus (f8) with the intent of her becoming the first thing the viewer's eye would go to (owing to how sharply she was rendered). Even at this aperture I was pushing it a bit in terms of shutter speed (1/400s) when hand-holding the 600mm lens, but past experience and testing had taught me that the odds were better than 50:50 that the capture would be sharp. Even at this moderate shutter speed I needed a reasonably high ISO (3600) to get the exposure right...but I was confident that at this ISO I had enough dynamic range and tonal range to render the image as I wanted, and that noise would not be an issue at all.

Did I choose the right balance of exposure variables to get the shot "right"? I think from a technical perspective the answer is probably yes. But what about the creative side of the equation? This is much tougher to answer. Working up-close with multiple subjects always presents focus and depth-of-field challenges, especially when you have a 600mm lens in your hands and no time to change lenses! I briefly considered focusing on the background cub and throwing Ma out of focus, but quickly decided that with her physical overlap of (and interference with the sight of) the cub she'd simply end up being a major distraction to the composition. But when I focused on the closer of the two bears (mom), I saw some symmetry in their poses and it occurred to me that the symmetry might help convey the short story behind the image. Moreover, because I was aware of the normal hierarchy of eye-drawing power in an image (first to luminance, second to the sharpest portion of the images, third to colour differences) I was fairly sure that the eyes of anyone viewing the image would be drawn first to the sharply focused mom - and likely to the white of her eye - and then slowly they'd explore the rest of the image. I can't say for sure that I'm right here - these are simply the things I was considering while peering through the viewfinder...

NOTES:

1. This image - in all resolutions - is protected by copyright. I'm fine with personal uses of them (including use as desktop backgrounds or screensavers on your own computer), but unauthorized commercial use of the image is prohibited by law. Thanks in advance for respecting my copyright!

2. Like all wildlife images on this website, the subject is fully wild and completely unconstrained. Besides the potential impact of my presence, nothing has been done to intentionally alter or affect the ongoing behavior of the subject and, of course, there has been no use of any form of bait or other form of wildlife attractants (including vocalizations).

3. This image was captured during one of my two spring "Grizzlies of the Khutzeymateen" photo tours in May/June of 2013. Each year I offer trips into two different parts of the Great Bear Rainforest as well as one to photograph aquatic mammals and oceanscapes near the northern tip of Vancouver Island. And, in selected years, I also offer photo tours to locations to capture other highly sought-after subjects, such as various boreal owl species and wildlife of Canada's Arctic. Details about these trips can be found on the Photo Tours page of this website.

Digital Capture; Compressed RAW (NEF) 14-bit format; ISO 3600.

1/400s @ f8; -0.67 stops compensation from "recommended" matrix-metered exposure setting.

At the Computer

Full STOP - Threat Sensed. Khutzeymateen Grizzly Sanctuary, northern BC coast, Canada. May 31, 2013.

RAW Conversion to 16-bit TIFF Phase One's Capture One Pro 8. Three raw variants (different versions of a single raw capture) processed, differing by a total of 1.4 stops in exposure.

Further digital corrections on resulting 16-bit TIFF files using Adobe's Photoshop CC 2014 and Light Crafts Lightzone. Photoshop adjustments included compositing (blending) of the three output files from the raw converter using manual masking techniques, minor exposure and contrast tweaks, selective colour desaturation, and selective sharpening for web output. Final tone-tweaking performed using LightZone's "tonemapper" tool.

Species Status in Canada**: Special Concern (May 2002).

While Grizzly Bears (Ursus arctos) are not technically listed as "Endangered" in Canada, they have been extirpated from most of their historical range. Grizzly Bears are far more sensitive to intrusion/disturbance in their habitat than are Black Bears and are being increasingly forced into marginal habitat by human encroachment. The Great Bear Rainforest along the central and northern coast of British Columbia is one of the last strongholds of the Grizzly Bear in Canada, and even this population is coming under increasing pressure.

Sadly, because these bears reside in BC, there's a very real chance that their lives will be ended by a bullet. And, their head and paws will be cut off (leaving the carcasses to simply rot) so that they can be mounted and adorn the wall of some fearless trophy hunter (who will, no doubt, be cheered on by all the grasses, sedges and clams that will be saved from being so mercilessly eaten by these fearsome beasts).

The debate about the trophy hunting of carnivores can be broken into 3 arguments: the ethical, the economic, and the ecological. The ethical argument for the trophy hunting of grizzlies in BC? On that one - just go back and look at this image and read the paragraph immediately above. The economic argument? Well, it's on even shakier grounds - not only does bear-watching in BC generate 11-15 times as much revenue as bear hunting (and employ 10-15 times as many people), but the revenue generated by bear hunting doesn't even cover the cost to the BC Gov't of managing the hunt itself - it's a net loss to the taxpayers of BC (all studies related to these economic claims can be supplied on request). The ecological argument? Yep, you guessed right - there isn't one. As a matter of fact, an increasing body of sound, peer-reviewed scientific studies have shown how the guild of carnivores at the TOP of the food chain are exceptionally important to the overall health of ecosystems - everything from ensuring continued biodiversity through to maximizing that amount of carbon dioxide the ecosystem can absorb (climate change consequences, anyone?).

So why does the trophy hunting of carnivores (and bears in particular) continue to exist in BC? Good question. Well, it sure isn't because of public support - just under 90% of British Columbians are against it. And many First Nations have banned it in their territories. Sadly, it appears that little more than the fact that a handful of elected officials (MLA's) in a few rural ridings fear the backlash from voters if they stand against trophy hunting is keeping trophy hunting alive.
