The basic technique is to get close to the subject while balancing the lighting between foreground and background.

Although I had a lot of high-priced cameras along on my Solomon Islands trip, I also decided to take along the less expensive and friendly Canon G7X compact and the Fantasea G7X housing. The Canon G7X has had a lot of play in photo news sources as a “G16 replacement” and answer to the popular Sony RX-100. The Canon G7X sports the same sort of 24mm (35mm equivalent) f/1.8 lens, and large 1” sensor that should give it the image quality of m4/3rds cameras, and a competitor to the the Panasonic LX-100 and other similar high-end compact cameras. I wanted to get a feel for how it stacked up.
The Olympus TG-4/TG-3 Cameras have a robust selection of flash modes. Generally all you have to do is put the camera in auto/forced flash mode, but on some strobes TTL won’t sync with these settings. Fortunately Olympus has provided an alternative sync mode that does seem to work. To access it you must first enable it, then select it from the flash settings. It is best used in Program or Aperture camera modes. Here's how to set it up...
I’m just back from a 10 day live aboard dive trip to the Solomon Islands. I had packed 5 different cameras and systems to do a round table of testing and comparing in order to write some practical reviews.
As usual, I spent time going over each camera system making sure I had packed all the necessary batteries, chargers, lenses and attachments. All was reasonably packed into two cases. One was carried aboard and my Seahorse hard case and dive bag/clothes checked. With everything spread out the day before, I tried to balance their weights, airline requirements for lith-ion batteries, etc. What I didn’t do was to make sure that essential chargers, batteries and mounts were all packed together with each camera. Oops.
Underwater, the closer we look, the more we see. Slow down, go small and look into the plants and growth. You’ll find surprisingly beautiful and fascinating subjects. Macro photography allows photographers to get in close, reducing the amount of water between the camera and subject; bringing out color, sharpness and details in photos.
