I have never been on an Aggressor boat. Are you saying that the owners/operators aren't divers? Or that the customer base isn't divers?

That's a great tag line. It describes every live aboard dive boat on the planet.

This is why I will never enter a NAUI competition. It is common for a competition to ask for a limited right to use winning images to promote future competitions, but asking for full ownership of all entries is simply unethical.

Actually, the Helium on earth was not created by Hydrogen fusion in a star (except indirectly). All of the Helium that was present on earth when it was formed has long since been lost to space. It turns out that Helium is so light that it floats up to the upper atmosphere where the temperature...

Hi All, Last week my dive club had a seminar day at SBCC Marine Tech and got a chance to play with their commercial dive gear. It was a blast and made for great photo ops. Here are a couple photos. Click on the images for more details. The first one is of me gearing up taken by a friend...

There is another problem with a wide zoom like an 18-105. When using a dome lens, you need to have the nodal point of the lens at the center of the dome to avoid spherical and chromatic aberration. As you change the zoom setting the nodal point moves around quite substantially. So, by using...

Here are a few more for your perusal. I have somewhat mixed feelings about the second to last one. The water was getting pretty stirred up so I tried to make lemonade out of lemons by capturing the sun rays, which I got alright, but I am not happy with the particulates in the foreground. What...

Thx. I try

Last week I had to go to a tradeshow in Orlando. I decided to go a day early and do something fun. I drove from Orlando to Crystal River and went snorkeling with the Manatees in the springs. Even though the Florida Manatee is endangered and there are only about 3000 left in the wild, you have...

I don't know much about Cabo day trip operators, but just so you know, Socorro is NEVER a day trip. It is 250 nautical miles from Cabo!

I'm surprised no one mentioned the most important tip! Practice with your camera on dry land. Dont try it underwater until you can get sharp images of flowers, your dog, etc.

Last year I donated a couple photos for use in the interpretive posters along the Pacific Grove Beach walk. I live 5 hours drive away and so I don't make it up there very often. A couple months ago I was visiting a friend and made a detour on the way back to check them out. The whole walk is...

I just got back from the Revillagigedos aboard the Nautilus Explorer, and although it will take some time to go through my photos I thought I would share a couple of my favorite Manta pics from the trip. The Mantas are just extraordinarily beautiful and elegant. I tried to capture the essence...

Yes. They said that the island was being closed for "naval excersizes". I thought immediately of San Clemente closures. I just wish that the closure had been published in advance. There are only three boats that make it out to Socorro so it wouldn't have been too onerous to let them know...

Hi All, I just got back last night from a trip to the Revillagigedos on the Nautilus Explorer. I will write a trip report in a few days when I have a chance to go through my images. However, I thought I would let you know about a recent development. We spent two days at San Benedicto and two...

I am pretty sure that this was primarily feeding behavior too. When I first arrived on the scene and found them swirling around, I noticed small white things floating in the water. I grabbed one and found that it was a squid tentacle. I figure that they sea lions had chased up some squid from...

When you are neutrally buoyant, you are not "weightless." However, rather than arguing over the definition of weight and mass, it would probably be more helpful to describe the practical difference. For example Nasa uses pool training to simulate weightlessness because it is similar (but not...

I too have the DUI dry gloves with zip seals. As the previous poster indicated they are a bit awkward because you have to don and doff the suit with the gloves attached, but I have gotten pretty good at it. I have been diving the same gloves for the past couple years and haven't had any leaks...
