Milder weather is good news for manatees
The Florida Fish and Wildlife Conservation Commission (FWC) has recorded fewer Florida manatee (Trichechus manatus latirostris) deaths in 2012 than in the preceding two years, which they attribute largely to milder winter temperatures. The FWC logged 392 deaths last year, compared with 453 in 2011. Collisions with watercraft caused 81 fatalities in 2012, compared to 88 in 2011.
The FWC works to enhance access to warm water sites for the manatees. Recent projects include the restoration of Fanning Springs, which give the animals access to a natural warm-water habitat off the Suwannee River.
Sony embraces 4K at CES
At Sony’s press conference at the CES show in Las Vegas, the company was all about delivering and creating 4K footage, Engadget reports. On display was a prototype 4K consumer camcorder which appeared to have a fairly standard prosumer form factor and features and displayed a Handycam logo. Also announced was the HXR-IFR5 Interface Unit, which upscales existing HD footage to 4K. The RAW video files produced by the unit are in 4096 x 2160 resolution. These new devices join Sony’s announcement earlier in the week that it will release two new affordable 4K TVs this summer.
Nikon announces new mirrorless products
Nikon has announced the release of two new mirrorless cameras and two new 1 series lenses. The 1 J3 and S1 both have phase-detection and contrast-detect AF. The J3 has a 14.2-million pixels CMOS sensor which supports an ISO range from ISO 160-6400. The S1 has 10.1-million pixels and a native ISO range ISO 100–6400.
Nikon has also released details of two new lenses for the 1 series, a 6.7-13mm f/3.5-5.6, and a 10-100mm f/4-5.6. The former gives a 100° field of view equivalent to a 16-35mm lens on a full frame camera.
Lastly, the company has announced an underwater housing for the J3.
Reviews: CrumplePop plug-ins for GoPro POV cams
Steve Douglas presents reviews of CrumplePop’s correction filters for GoPro POV camcorders. CrumplePop has released an HDR plug-in that helps restore color balance within footage, and a plug-in that corrects the fisheye effect that is created by the GoPro’s lens.
Steve summarises that both apps are very useful for those who use GoPro footage within their productions.
Giant squid filmed at 2,950ft
The Telegraph reports that a team from the Discovery Channel, Japan’s National Science Museum and NHK Japan have filmed a 10ft (3m) giant squid (genus: Architeuthis) at a depth of 2,067ft (630m) using a submersible last July at a site some nine miles east of Chichi island in the north Pacific Ocean. They then followed the squid down to a depth of 2,950ft (885m)
The squid had apparently lost its two longest arms, so the team extrapolated that the length of the animal if it had its arms attached would be 28ft (8m). I’m sure that there is good science in predicting this. The film is apparently the first of a giant squid in its natural habitat. The footage will be going to air soon.
