Jump Settings For Blue Water Video

Jump Settings For Blue Water Video

By Sy Harris

It is important to always think about your camera and what settings it’s in before jumping into the water. Below is a setting checklist you should follow before and at the beginning of every dive. It should be the mantra you chant each time you enter the water. If your camera is set to these specifications you will be ready to capture great footage in almost every situation."

Strobes for digital cameras

Strobes for digital cameras

by Ikelite

Strobes for many of the new digital cameras must fulfill requirements that are different than what has been required for film cameras.

Some of the digital cameras require a small initial preflash before the standard flash, allowing the camera to gain exposure information. The camera may not provide the best results without this preflash. The two flashes happen almost instantaneously. Most strobes for film cameras can not produce this rapid flash sequence."

OceanNEnvironment

OceanNEnvironment only undertake projects that yield measurable goals and objectives.

Our positional statements are:

• 
  
  The single MOST important reason why coral reefs are dying is that there are too many people on this planet. We believe that if the focuses of our conservation efforts are directed to benefit the local people, like feeding them, or providing them with resources to benefit from the eco - tourism, the reef will save itself.
• If long-term conservation is to take place - it is dependent on our capacity to persuade local people that they will be ‘better off’ protecting the natural system than degrading it, by creation of markets for goods and services in an environmentally manner.
• If local people gain from sustainable use of the coral reef through tourism, they will protect this asset and may even invest future resources into it. Marine parks and reserves cannot survive without the support of the local people.
• We believe that understanding, appreciation and love begets preservation and protection people can only protect and preserve what they love therefore it is important that they have affinity and connection to the environment. In this aspect OceanNEnvironment actively support marine research and educational programs with financial grants

What is High Definition Video? or What is HDV?

What is High Definition Video? or What is HDV?

By Sy Harris

When choosing an HDV camera you’ll notice the HDV format comes in a variety of resolutions, scan modes and frame rates. Understanding what these designations mean however, can be very confusing. For instance, the Sony FX1 shoots in 1080i or 1920x1080 60i, where the JVC GR1 shoots in 720p or 1280x720 24p. Both are considered HDV, but how are they different? What is 720p? What is 60i?

To be considered HD, video must follow certain criteria. It must have a 16:9 aspect ratio, varying frame rates, and resolutions of 1080 or 720 horizontal lines. The chart below breaks down these constraints and will show you the main variations of the HDV format."

Making the Jump: Going Digital Photo

Making the Jump: Going Digital Photo

By Brad Brown

Since the day I reviewed the first slides produced using my Nikonos V seven years ago I have asked myself 'Why are so many of my images rubbish?' I can't blame the camera. The Nikonos V is capable of producing magnificent images. I've concluded rather that the problem lies with my inability to use the camera to its fullest potential.

The learning curve is steep. I made my greatest jump up this curve during a week of diving in on the island of Sipadan. The resort photo pro processed E6 several times a day. I was able to apply what I learned reviewing my slides within hours of exposure. Consequently my rubbish heap shrank as my relative quantity of keepers grew. When the digital SLR became an option I saw the potential right away. The prospects of
1) instant image review
2) never running out of film
3) autofocus
made the switch from the Nikonos alluring.

I made the decision to buy a Canon 20D and a Subal C20 housing. Since my purchase I have been able to build upon my Nikonos experience while benefiting from those advantages a digital SLR affords. The principles are the same. Only the medium and the methods are different.

My rubbish heap is now a virtual trashcan on my Mac's desktop."

●Exclusive rechargeable Ni-MH battery for YS-250PRO with the optimum efficiency.

The YS-250PRO is designed for demanding professionals, packed with revolutionary new features to meet the challenges of digital photography. A large circular arc tube emits a powerful flash at guide number 32 (its value on land, ISO 100/m) when power is set to FULL. It provides incremental manual flash power adjustment in 12 steps for graduations of light.
The YS-250PRO is lightning fast: it recycles in 1.8 seconds. Its high-capacity Ni-MH battery, designed exclusively for the strobe, stores enough power when fully charged for 200 full flashes. A high-luminosity white LED target light in the center of the strobe shows precisely where the strobe is pointed, and a ready lamp and a TTL confirmation lamp on each side of the strobe indicate when the strobe is charged and when it has been controlled by the camera’s TTL. An audible signal sounds when the lamps light so you can concentrate on your subject in the viewfinder.
The YS-250PRO includes other sophisticated features such as three fiber-optic cable sockets (2 of them with slave sensor), pre-flash cancellation that handles up to two pre-flashes from a camera.
The YS-250PRO: at home in the water day or night, satisfying your demands for the best possible images.
