Walking on Thin Ice… One More Polar Bear

Polar bear (Ursus maritimus) crawling on thin ice

It has been quite a while since I published an image, so I thought I would put up a funny one, one that I really like about Polar bears (Ursus maritimus) because it shows the (deceivingly) goofy side of these white, fluffy and yet deadly giants.

Beside being funny, the image actually shows an interesting behavior: when they are approaching thin ice, polar bears assume this position and start crawling on the ice so that their considerable weight more evenly spreads out a wider surface, thus reducing the risk of breaking through the ice and going for a cold swim.

Polar Bears

I am reblogging this post that was published today on The World According to Dina, a magnificent blog about the northern part of the world, photography, literature and symbolism.

The post is the result of a recent collaboration project on Polar bears (Ursus maritimus) between one of the authors of that blog, Dr Klausbernd Vollmar, a German-raised, English-resident psychologist, symbologist and author, and myself. When Klausbernd asked me if I wanted to be a part of this project, I was very excited and honored and of course I enthusiastically jumped on board!

More specifically, the post/article contains a part with general natural history information about polar bears (this is the portion that I researched and contributed) and a part dealing with the symbolism of the polar bear (which Klausbernd authored), plus a selection of my polar bear photographs.

I am very pleased of this collaboration and I think the end result shows the hard work that both of us put into it – but of course I will let you, dear readers, be the judge of it if you feel like visiting The World According to Dina (which I think you should, regardless of this specific post) and reading the article! Needless to say, your feedback would be most welcome! 🙂

Thanks,
Stefano

General Information
Polar bears are the largest land carnivores in the world and the most carnivorous of the bear species: they primarily feed on seals and, to a lesser extent, walrus and beluga whale. In search of their prey, they may often be found in areas of shifting, cracking ice where seals may surface to breathe air. Adult males (which are larger than females) measure up to 2,5 m in length and can weigh up to 720 kg!
Since they spend much of their time on Arctic sea ice, they have evolved to adapt to such extreme conditions: their white fur provides camouflage in their environment and is thicker than any other bears’, even covering their feet for both warmth and traction on ice; their skin is black to absorb heat from sun rays; and a thick layer of fat provides buoyancy and insulation.

Valentine’s Day First Date?

CANADA, Churchill (Hudson Bay) Polar bears (Ursus maritimus) interacting

Because that’s what this image reminds me of when I see it! A clumsy kiss, some indecision mixed up with curiosity, you know… 😉 Anyway, Happy Valentine’s Day, wherever you are and whichever way you plan to celebrate it! 🙂

I took this photograph of Polar bears (Ursus maritimus) interacting in Canada’s Manitoba province, where every year many polar bears congregate in late Fall, waiting for the temperatures to drop so that the waters of the Hudson Bay freeze and the bears can venture out on the ice in search of their favorite food item – seals. More about this on a future post.

Herculean Polar Bears

Polar bears (Ursus maritimus) confronting one another in a snow storm

With winter storm Hercules being the first big storm to hit New England in 2014, two mere days into the New Year, it only seems appropriate that I share another image from my Polar Bear Gallery, portraying two Polar bears (Ursus maritimus) play-fighting in a snow storm near Hudson Bay, in Canada’s Manitoba province: if you live in an affected area, stay warm! 🙂

Raw Moves: Three Reasons for Shooting RAW Instead of Jpeg

Polar bears (Ursus maritimus) play-fightingCaption: Canada, Hudson Bay – Polar bears (Ursus maritimus) play-fighting

A while ago, the exquisite Fairy of the North, Dina (who so elegantly authors the blog The World According to Dina, masterfully combining her beautiful images with perfectly selected quotes to complement them) asked me if I would write a post about why I think anyone who shoots digital and takes his or her photography seriously should shoot RAW as opposed to straight off the camera Jpegs.

By the way, before we even get to the point, what is a RAW file, just in case you were wondering? A RAW file is essentially the equivalent of a film negative in the digital age. Every camera manufacturer has their own proprietary formats of files containing the raw (hence the name), unprocessed input captured by the sensor. In fact, RAW files are called in several different ways and have different extensions, depending on the various camera makers: for instance, Nikon’s are called NEF and Canon’s are called either CRW or CR2, depending on the models.

Unlike straight out of the camera Jpegs (which are the result of the camera’s computer processing the sensor data, making arbitrary choices that you as the photographer cannot control and producing a file format that is immediately viewable by anyone), RAW files need to be processed through specialized software such as the camera manufacturer’s proprietary processing software or third-party software such as Adobe PhotoShop or Lightroom or Apple Aperture and then converted to a usable file format, such as TIFF, PSD or Jpeg.

In essence, processing a RAW file requires more of the photographer’s time because he or she has choices to make (in terms of optimizing white balance, exposure, contrast, color balance/saturation, etc.) but puts the photographer back in control of his or her creative decisions and what’s best, in a totally non-destructive, reversible way (more on this later).

Having said that, here are the three main reasons why I think you should set your camera to shoot RAW instead of Jpeg:

1. Unlimited White Balance Adjustments: This is one of the most powerful reasons for choosing a RAW file over an in-camera Jpeg. In short: if for any reason you shoot an image using a white balance setting that is not optimal for the scene you are shooting and you have your camera set to produce a Jpeg file, then you are stuck with that suboptimal white balance and changing it (or at least improving it) will be a difficult and time-consuming task to be performed in your image processing software. If instead you shoot RAW, you can easily correct your white balance with just one click in your processing software. Done!

2. Lossless Process: Jpegs are image files that are considerably smaller than other formats. This is because they utilize a compression algorithm that is lossy, meaning that it discards a bunch of color information from the image to make the file smaller. The more you compress, the more subtle color transitions and image sharpness you lose. In addition, image data loss is cumulative, meaning that every time you save or re-save a Jpeg file, you lose information that cannot be recovered later on. If you shoot RAW instead, you retain all of the information captured by your camera’s sensor, forever. This means not only that, should you need to perform some intensive editing of your image you will have more information to work on, but also and more importantly that you will forever retain full access to all the information that the sensor originally captured.

3. Non-Destructive, Reversible Editing: If you shoot Jpeg and then edit your file in post processing you can then either keep it as a Jpeg when you save it (in which case, all your edits will become permanent AND you will experience image data loss when you save your processed Jpeg) or work using layers (if available in your processing software). The latter is definitely the way to go, because layers can always be discarded later on, should you wish to process your image differently. However, Jpegs do not support layers, so if you use them and want to retain them, you will have to save your processed file in a format that supports layers, such as TIFF or PSD which are both lossless formats but end up in bigger file sizes. Instead, if you shoot RAW and process your RAW file, all your edits will be stored in a so-called “sidecar file”, meaning a small text file that goes hand in hand with your RAW file and contains all the information about the edits that you performed. This means that your RAW file will never be altered and you will always be able to change any of your edits at any time in the future with no damage to your image file or information loss. Pretty cool, huh?

As a final note, even if after reading these compelling reasons for shooting RAW 😉 you were to choose to continue shooting in-camera Jpegs, at the very least make sure that as soon as you download them to your computer you immediately save them to a lossless image format: as we said earlier on, not only will this let you retain your adjustment layers if you so choose, but it will avoid image degradation every time you re-save that Jpeg.

A Valentine’s Day Polar Bear Hug

Polar Bear Hug (Ursus maritimus)

As some of you know, I love bears, of any species, and I love it whenever I have the opportunity to see them up close (in a safe way, of course), observe their behavior and photograph them. They make for great photo subjects.

This image was captured on a trip to the Western shores of Hudson Bay in Manitoba (Canada) where in or around late October/early November large numbers of polar bears (Ursus maritimus) congregate after hibernation waiting for the sea water to freeze so they can venture out on the ice to try and capture one of their favorite preys: seals.

While they hang out by the shore and wait for the temperatures to drop so as to make the magic happen once again, younger polar bears often kill time play-fighting. Witnessing this “boys will be boys” kind of rough game is fascinating, and if you keep your eye in the viewfinder long enough, with some luck you may photograph them while they strike poses that can look awkward, funny, dramatic or… just shweeeet like the one in this image, which two years ago these days was published as a Valentine’s Day poster insert in the Italian magazine Focus Junior.

However, appearances are sometimes deceiving because, in the “play-fight” portrayed in this image, the bear on the right was actually biting the other bear’s ear while holding its victim steady with its strong paws. You might therefore say that this image would be more appropriate to illustrate an ear piercing ritual of sort or that infamous “if you cannot beat them, bite them” Tyson vs Holyfield moment… 😉

Happy Valentine’s Day to those of you who celebrate it!
