Rare treatment for record 53 hours saves diver | Star Tribune Rare treatment for record 53 hours saves diver Article by: JEREMY OLSON , Star Tribune Updated: September 27, 2014 - 5:58 AM For Lake Superior diver forced to surface too quickly, HCMC doctors try protocol that they looked up in the...

Quite a few years back I used an INON UCL wet lens. I had a lens caddy to hold the lens while not in use, but I tethered it to the camera tray using a fishing leader. I looped one end through itself and wrapped it around the body of the lens, then taped it down with bright yellow tape. This held...

Seeing as I have only done cave trips this year, here are the three that stand out to me.

That's a tough one to answer in isolation since so much depends on the camera you are using (different cameras may perform differently at the same ISOs), the lens setup you are using (lenses can have different aperatures plus the use of TCs can affect how much light you can get wide open)...

I often travel with a similar amount of gear as carry-on. What I do is hand carry my housing with camera, lens and port on it separate from my carry-on camera backpack, which contains everything else. Airlines often allow a personal item in addition to your carry-on, which can be a camera...

Wow, thanks Lynne, I am humbled!

Here are a few images from this week so far. I never get tired of coming down here.

I think one of the more important questions that has yet to be asked is... what kind of photography or type of shots do you want to do?

Are you sure the problem isn't the sync cable? Especially if you have the older one without the strain reliefs at the connectors. I found those were really susceptible to damage. I went through a number of failed cables that way (and Ikelite won't repair them, you have to get a new one). The new...

Thank you Jan, I appreciate the comment. As a side note, if you ever get a chance to dive the Philippines, it is really amazing for macro photography. For the non-macro shots, the ones you mention are all taken with the 60mm from a slight distance, not more than a few feet max. The self portrait...

I would say get the Nikkor 60mm micro as well (micro is just Nikon's name for macro). If you're new to UW photography, this would be a good lens to start with if you want to get into macro shooting. It will allow for some portraiture shots as well (nothing too big though). It is the lens I shoot...

What are the state of the reefs? Have they recovered from the coral bleaching from a couple of years ago? I went twice in 2010, March and December. Somewhere in between, the water temperatures got abnormally high and by the time I was there in December, just about all the reefs were dotted with...

Hmm... not sure what to say about this other than there really isn't any substitute for experience, so it's not so much about how fast you learn something, but putting the requisite time in to hone those skills. I thought I was good at 100 dives. Now at over 2000 dives I look back and shake my...

Judging from the pictures, it looks like you have some motion blur due to the low shutter speeds. Lynn is correct about the strobe being the dominant light source in your shots, but I suspect that due to the low shutter speed and the relatively bright ambient light, you're getting some ghosting...

I have both lenses and use the same port on the aquatica system. I just need to use a port extension with the 105. I am not sure about ikelite.

I have tried the 14-24mm f/2.8 underwater. The main issues are as you describe - lack of ability to front mount diopters, which results in some pretty significant loss in sharpness in the corners. Even cropping a little bit only helps a little, plus that kind of defeats the purpose of having...

Wow, over 2 years to settle a claim. The check may take a few days to clear.

What it was that I didn't understand was that the dSLR inside the housing was deemed to be an explosion risk while the dSLR without the housing would not have been an issue. The best I figure perhaps is that they might have had sealed housings that have breached due to a positive pressure...

The flight attendant said she checked with the captain and he said it was ok and they let it go. I still don't know why they deemed it an explosion risk due to over-heating.

I suppose it is possible about the sealed housing. For me, I always remove the o-rings in the eyepiece so that it is not possible for a pressure differential to build up within the housing. However, when I asked the flight attendant why there was a greater risk, there was no reasonable...
