“For Sale: Canon EOS 1000D.

Description: only used underwater once, in the Pacific Ocean, for approximately one year.

Actual story: found off the end of a wharf in Deep Bay, BC while I was diving on a job for the harbour. I removed the SD card, cleaned it up, stuck it in a card reader and after being underwater in a corroding camera since August 2010 - it works! Approximately 50 pictures on the card from a family vacation. If you know a fire fighter from British Columbia whose team won the Pacific Regional Firefit competition, has a lovely wife and (now) 2 year old daughter - let me know. I would love to get them their vacation photos :)

There are other clues on within the pictures - I think we should be able to track them down (not sure he’ll want the camera back tho).”

This was posted by Google+ user Markus Thomson and he has subsequently discovered the camera’s owner. Plans are now afoot to reunite the owner with his pictures, although he may not want the camer back.

BBC Nature features an article about a time-lapse sequence shot as a part of the Frozen Planet series currently on air. Filmed under the ice at Little Razorback Island, near Antarctica’s Ross Archipelago, the camera crew captured the growth of a “brinicle”, which formed as a result of sea water freezing around brine released from sea ice. As this brine was well below zero and much denser than the water surrounding it, it formed a frozen icicle hanging underneath the sea ice. Due to its temperature, the brinicle is lethal to anything that it touched, freezing them instantly.

In the article, cameramen Hugh Miller and Doug Anderson talk about how awkward it was to get the equipment into place, and the fact that The large weddell seals in the area had no problems barging past and breaking off brinicles as well as knocking over the filming equipment.

Photoshop trainer and author, Scott Kelby, has written an open letter to Adobe management protesting about a change to their upgrade policy which will come into effect with Creative Suite 6. Until now, registered owners of the previous three versions of the software have been eligible to upgrade to the newest at a discounted fee. However, beginning with CS6 the company will only allows owners of the previous version (in this case CS5 OR 5.5) to upgrade and owners of older versions will have to re-purchase CS6, rather than being able to upgrade to it.

Adobe are offering 20% off upgrades from CS2, 3 and 4 to CS 5.5 until 31 December, presumably to allow people to then upgrade into CS6 when it is released.

Current Biology has published a research paper by researchers at Duke University showing how two species of squid can quickly switch between transparency and pigmentation to essentially become invisible. The two species studied, octopus Japetella heathi and the squid Onychoteuthis banksii, are both deep water dwellers, and it is theorized that the animals can switch between a transparent resting state and a pigmented camouflage state when light is introduced. Since many deep-sea predators have light emitting organs that they use for hunting, this pigment change would give these species an advantage in avoiding detection.
