I photographed this Common Murre (bridled form) against the shadows under the cliffs during my recent Deluxe Puffins Galore and so much more workshop in Québec, Canada. It was a dark and cloudy morning with a distinct absence of light (to say the least). I knew I wanted to freeze the wingtips, so I chose 1/5,000 of a second shutter speed, leading me to use an ISO of 20,000 while wide open at f/6.3.
Common Murre (bridled) calling in flight
The opportunities were endless during the early morning boat cruise below the cliffs of BONAVENTURE ISLAND during my recent GANNETS GALORE and so much more workshop.
I love the white spectacles on this bridled common Murre. The key to success while working at 20,000 ISO is to pay particular attention to two things:
Ensure you have exposed the image correctly and pushed the whites all the way to the right of the histogram; correcting a poorly exposed image will always result in much more noise than getting it right in the camera.
Try to work full-frame; the more you crop an image, the more you magnify any noise that there may be.
Common Murre Bridled Form
Some Atlantic adult Common Murres in breeding plumage have a "bridle": a white eyering with a white line extending behind it. The Common Murre (Bridled) is a race or sub-species of the Common Murre, which is seen in North America. Although the Common Murre is seen in the Pacific and the Atlantic Oceans, this race is only seen in the Atlantic waters. It can be easily recognized by its bold white facial markings. It also has different coloured eggs than the Common Murre. Both races live among each other.
