Inon Z220F Strobe Replaces Z220
Inon has released a new strobe, called the Z220F. The Z220 has been discontinued and replaced by this new strobe. The main difference between the two is that the “F” model has a focus light that can be turned on and off by the photographer, and it does not have an aiming laser.

SeaSpace 2005 Report
Seaspace 2005 was held in the Reliant Center at the Astrodome complex in Houston June 4th and 5th. Eric Cheng and I attended the show together again this year, but this time, we did not have any duties, other than checking out the booths, seminars, and workshops of interest to the Wetpixel underwater photography community. If you are into large “scuba gear shows” like DEMA, then you would have considered this years event to be pretty small. However, from a photo-centric viewpoint, the show was perhaps the best of the 5 that I have attended. This article will be a brief summary of the show, as most of the information is contained in the photographs and photo captions.
Optimal underwater macro aperture
Borut Furnlan sets out to answer the following question: “... what f-stop should I use at underwater close-up photography with a reproduction ratio of 1:1 (life size) to obtain the best compromise between depth of field and the list drop in sharpness due to the diffraction of light on aperture blades?” Borut also answers the following question: do objects underwater look 1.33 times bigger or 1.33 times closer? [Thanks, James]
Borut uses film, but the test is still an interesting read for digital guys (digital systems have different sensor sizes and pixel densities, which affect circle-of-confusion calculations).
Disney Hong Kong and Shark Fin Soup Update
Here’s an interesting article that shows that the protests and bad media may be having an effect:
- HK Disney answers soup critics (June 9)
Disney will only serve legally-harvested shark fin, and will hand out pamphlets to interested parties
On my personal website, I’ve posted a template for a letter you can e-mail to Disney executives (easy, one-click e-mail links also included).
And speaking of protests and media campaigns, Wetpixel member Jason Grimes is also organizing a letter-writing campaign. Continue reading for more information.
Celebrate the Sea Photo Competition Results Posted
The Celebrate the Sea Underwater Expo and Film Festival has announced the 2005 winners. Wetpixel member Darek Sepiolo (aka Darecky) from Poland took a gold medal in the black and white print category with his photo of Southern stingrays.
Darek’s photo also placed in the Chech PAF Tachov competition.
Wetpixel Sardine Run Expedition 2006
Join us in South Africa for one of the world’s greatest spectacles of nature. Every year, the world’s greatest marine migration takes place off the South African Wild Coast. Millions of sardines follow the cold winter currents moving north toward the warm Indian Ocean, bringing with them thousands of predators: dolphins, sharks, whales, seals and marine birds.
Doug Perrine won last year’s British Natural History Museum’s Wildlife Photographer of the Year award with an image he took while on a sardine run expedition.
Wetpixel has 10 spots for this amazing trip scheduled for June 21-30, 2006. Continue reading for more details. APR 26, 2006: THREE SPOTS JUST OPENED UP (LATE CANCELLATIONS).
Wetpixel Great White Shark Expedition to Guadalupe 2006
Wetpixel heads to Mexico in August of 2006! Photograph great white sharks with Eric Cheng and Norbert Wu aboard the Solmar V in the clear, blue waters off of Guadalupe Island, Mexico. This is a special, 7-day expedition. In addition to the normal surface cages, we’ll have a large “cinema cage” at 20’.

Zigview Angled Viewfinder
DPreview.com reports that a UK based company called Intro2020 is distributing the Zigview angled LCD viewfinder for SLR cameras. The unit is basically a tiny CCD video camera and LCD monitor merged with a case that mounts over your camera’s viewfinder, much like a right-angle finder. This unit may be of interest for underwater photographers as it looks like it could be enclosed in a small box and mounted on an underwater camera housing. The 1.9 inch diagonal LCD display, while probably not fine enough for determining focus, would be very helpful for macro composition.
