Introduction For a long time, I held off getting a fisheye lens since I mainly photograph wrecks and really appreciate the "straight lines" that a rectilinear lens provides. But, there are advantages to a fisheye and I finally took the plunge but with a very vintage lens adapted to a modern Sony mirrorless camera. The [...]
Background One of my favorite rectilinear lenses for underwater wreck photos is the Tamron 17-28mm. It isn't that I don't like fisheye lenses, but for wreck photography (which is 90+% of my photos) I really prefer the straight lines from a rectilinear lens. Given the outside diameter of the Tamron 10-17 lens and the N100 [...]
Background Quite a few years ago, I posted about the DIY dual cam band brackets that I had acquired through Mike Hall. I've had numerous people reach out to me to get more details and to build their own version of these. The last time this happened, the person offered to build me a new [...]
NB 1: This post is probably only interesting to those who conduct deep rebreather dives OR anybody who just wants more information about how the rEvo rebreather works. NB2: Most rebreather divers should never need to do this. Please don't modify your system unless you know how (and why). I'm supplying this for any rEvo [...]
Background As I've said many times, I have a "love / hate" relationship with scooters. They are very useful tools and IMHO increase safety on deep dives -- but there is a tradeoff in complexity, additional gear, etc. I know some people who have mastered using a scooter and camera at the same time but [...]
Note: This is probably more in depth than the "casual reader" probably wants but I wanted to document what I brought to help future Antarctic trip travelers -- especially those diving or doing photography. The ice was here, the ice was there, The ice was all around: It cracked and growled, and roared and howled, [...]
Background I have been trying for quite some time to find a good solution for listening to music underwater while on deco. It can get very boring and I love music so it seems like a good idea. However, it hasn't been easy to find a solution which meets all my needs. In the previous [...]
(NB: This post is targeted at rebreather divers) The purpose of this post is to detail the situation when you would want to manually "vote out" a cell on a Shearwater computer and alternate solutions considered. Background The way I have my rEvo configured is that three oxygen cells are connected to the main Petrel [...]
NB: This post is probably not very interesting to non-divers. Background Believe it or not, I have recently been (gasp!) doing some rebreather dives at recreational depths, such as building a photogrammetry model of the Yukon and model of the Corsair south of Pt Loma and I have a few other projects at that depth [...]
I had recently written about the benefits of Shearwater making the SurfGF field persistent after clearing deco but was also waiting for that change to be "back-ported" to the Petrel2 hardware. I noted at the end of the article that a Shearwater support engineer said they were going to make the changes available in the [...]
