I have used Panasonic 20mm and 14-42mm kit lens for underwater photography for more than two years. These two lens can't focus on close objects, so it's really difficult to use them to take pictures of small stuffs with good results. Hence, I bought a second hand Panasonic 45mm Macro lens to improve my underwater pictures.
The minimum focus distance of the lens on the lend is 15cm(0.49ft). How big the object taken by the lends can be? The diameter of the coin below is 2.6cm(1.02in), and the image of it taken by Panasonic GF1(4/3 mirror less) underwater is like this:
So, if you take a picture of a coin-size frogfish, it will be approximately like this: ...

It would not have been a complete DEMA, without visiting the Ocean Geographic Society booth. The artwork and hard work that goes into the production of this eco-oriented magazine, is shown to be a labor of love. The enthusiasm of the folks at Ocean Geographic is catching. Dedicating time and extreme effort, both above and below the surface, to bring stunning photos, and in-depth coverage of the splendor, and devastation that are the world's oceans. Founded in 2007, "It is the mission of the Ocean Geographic Society to kindle the natural compassion of the being by informing and inspiring the citizens of the world to conserve and preserve our natural world." ...

At DEMA 2014 in Las Vegas, I was honored to meet the wonderful people of Dive Pirates. This group of extraordinary people have come together to make a place for those who have a heart of steel, and a will so strong as to not be broken. What first caught my eye, was a pair of the most colorful pair of pirate pants I've ever seen.(more on these at the end of this piece) Outgoing and passionate about their roles in the diving industry, President Barbara Thompson, Susan DeVore, Executive Director; Sophie Wimberly, Vice President; and Charlie Oxley, Director of Operations, made an impact on on my stay at DEMA. Their work to bring the joy of diving to injured persons, and war veterans alike,...

Diving is cool… not just a little bit cool… it’s REALLY cool! Having dive experience and being a part of the SCUBA community makes each of us a member of a fortunate group. The great news is that this group is always looking for new members and as ambassadors of the SCUBA community (aka – SCUBAvangelists) we enjoy drawing people into the sport, either vicariously through our own dive stories or quite literally by introducing them to diving for themselves.
Here are 4 ways you can share your SCUBA! Dive In to the Under Pressure Dive Blog for more!

Why use double strobes for UW macro photography? The following two reasons are my humble opinions about it:
1. Reduce shadow
It's very easy to create shadow when we use only one source of lighting, like the picture shows below. I don't mean shadow is totally wrong or bad for the UW pictures. Shadow can bring more contrast and stereoscopic, however, many details will be lost in shadow.
Last time, I used double strobes to take the pictures of Porcelain Crab. As what we see below, there is less shadow on the subject and the picture is softer.
2. Various Strobe positioning ...

Since the very beginning you've been able to upload dives from your dive computer through the Diveboard plugin that was running within your web browser and connecting to your dive computers. This has worked great so far but came with a few issues such as the lack of an offline mode - you needed to be online and logged in to grab your dive profiles and upload them. Moreover browsers will soon drop the support for plugins like this. So we needed to evolve our plugin towards a more future proof solution.
So we crated the Divebaord Agent.
Just like the plugin, it will work on Mac/Linux/Windows. The agent lives in the tray and will connect to your dive computer and upload dive profiles to...

Out of focus again and again!!!
Can't focus underwater by auto mode, why not try MANUAL FOCUS?
I believe many divers who use mirrorless cameras and newly started to take macro pictures have the difficulty to focus on subjects. Using a mirrorless camera without a viewfinder, we have to take pictures by LCD monitor. This is one of the disadvantages of using mirrorless because it consumes battery faster. However, I take it as an advantage because it makes me apply manual focusing more easily.I went diving couple of weeks ago and practiced manual focusing with my Panasonic GF1. The picture below doesn't show clearly what the subject was, but it's a good example of manual focusing....

I went on a diving trip to Dumaguete, Philippines in August, 2014. I arrived at the diving shop around 12nn. The name of the shop is Liquid Dumaguete.
Day 1After simple lunch, I joined the shore dive at 2pm. Because the boat of the shop was in Apo Island for their diving day trip, we took a jeep to the breach of the dive site and geared up there. Unlike the white beaches I usually see here in the Philippine, the beach is brown color. The name of this dive site is Sahara. Like Sahara Desert, it's all sand in the sight. I spotted around 20 Garden Eels in a group right after getting into the water and was surprised why the dive master didn't point them out for us. After 10 minutes I...
