From the forums: More corner sharpness tests
Corner sharpness, with rectilinear wide angle lenses behind dome ports, is a commonly debated topic on the Wetpixel forums. There are many variables: different domes, different port extensions, different lenses, different formats (full frame, versus cropped sensor) and different dioptres or no dioptres at all.
Of course it is possible to determine the theoretically correct dome port and dioptre setup for a lens, but many photographers find that deviating away from the theoretically perfect setup gives them the flexibility and results they are after in the field. Underwater tests are invaluable in determining performance, and for seeing the differences between different setups.
A recent thread about Nikon’s impressive 14-24mm lens has blossomed into a discussion where several photographers, Karin Brussaard, Stephen Frink and Alex Mustard, have been kind enough to share some of their tests of both Nikon and Canon lenses. See their results and join the discussion.
Google launches Ocean in Google Earth 5.0
Google yesterday released the latest version of its Google Earth software, for the first time introducing a new layer called “Ocean,” an oceanography component that allows you to “plunge all the way to the floor of the sea, view exclusive content from partners like BBC and National Geographic, and explore 3D shipwrecks like the Titanic.”
Wetpixel member Bruce Yates (bmyates) had the opportunity to attend the official launch of Google Earth 5.0 at the California Academy of Sciences in San Francisco, and has written a report of the event, with photographs of notable attendees Sylvia Earle, Al Gore, and Jimmy Buffett.

Dome Port Diaries - Chapter 8: Season Finale - Into the Blue
Having migrated the gear from plane to rental car, and from car to dive resort, it was time to unpack and plan the next day. The evening of arrival, (what was left of it anyway), I reassembled the rig.
To fit in its Pelican case, I had removed the handles, each wrapped in the socks they give you in Business or First class; a small token along with a slightly wider seat and a “kit” containing toothpaste, a toothbrush, lotion, lip balm, and tissues.
While re-attaching the handles, I had my first panic moment; what the hell did I do with the hex wrench for the handles? Could I have forgotten something so obvious and important? ...

Protest shark finning in Sipadan / Mabul
Wetpixel member Syam was in the Sipadan/Mabul area over Christmas and discovered the local villagers catching and finning sharks on Mabul Island. Please help the conservation of sharks in the Sipadan area by writing in to encourage the resorts on Mabul and Kapalai and the Malaysian government to protect what few sharks that are left in the area and enlarge the marine protected area to cover the island group.
Please read the thread to get the contact information for the officials. Our voice as paying tourists does count and we should ensure our dollars are spent for the protection of the area and not contribute to its detriment.
恭喜發財! Happy Lunar New Year!
