Technical Scuba Diving
Tyler recently "re-identified" the Corsair that we dove last October. While we cannot be 100% sure, we are pretty sure based on accident reports that the original team mis-identified it (newer accident reports were released in 2012). In the search for more clues, Tyler started reviewing the photos I had taken. The "version" of the [...]
Strobes are a useful (I would call them essential) tool for divers. I never conduct a dive without at least one strobe and I usually have 2-3 on a dive. I think of strobes as the proverbial "bread crumbs" to find your way home. I almost always put one on the "down line" to a [...]
I have 5 sets of rebreather tanks (4 x 3L steel, 1 x 2L carbon fiber) and two drysuit inflation bottles. They used to just be strewn all over the place, usually shoved under my workbench cabinets: Tanks, tanks, and more tanks Custom tank racks My brother's hobby is to build "stuff" out of wood, [...]
NB: For the non-divers who subscribe, we use the format of "XX / YY" to denote the gas in a tank whereby XX is the percentage of Oxygen (O2) and YY is the percentage of Helium (He) -- the remainder is assumed to be Nitrogen -- and we put stickers on our tanks with that [...]
On a whim, I entered the Marissa 2020 Photo Contest and I recently found out that I was the runner-up! https://www.facebook.com/MarissaCharters/photos/a.230572168441/10159356247963442/ I submitted three photos to the contest: Tyler @ Corsair EngineTBM AvengerUSS Hogan Drew Wilson, who I've done a lot of diving with in the past year, won the contest (Congrats, Drew!). He is [...]
I was running the other day and one of my favorite Rush songs, Dreamline, came on. Today is the first anniversary of the passing of the great Rush dummer & lyricist Neil Peart, so it seemed like an appropriate day to publish this. I'm currently listening to Moving Pictures on vinyl and dreaming of better [...]
What to my wondering eyes should appear, but a DiveX Piranha P1 Scooter...
Background I started hearing about photogrammetry for documenting and visualizing wrecks about 2-3 years ago and had a passing interest. Since then, I've spent more time working on my photography skills (and equipment). I had watched a couple Wetpixel videos on photogrammetry recently and decided that, with Covid, I should learn more about it. I've [...]
Intro / Background After diving the UB88 wreck a number of times and also starting to delve into photogrammetry, I decided to combine both of these into a rather large project: Build a realistic 3D Photogrammetry model of the entire UB88 wreck. This project represents a number of challenges -- starting with the fact that [...]
Tyler and I dove a cool Corsair wreck last week (I'll post photos & the story soon) and I didn't shoot pictures for a photogrammetry model but figured I had enough of them to see what it would look like if I massaged them and put them into the software. It worked out pretty well! [...]
