  • The Foveon X3 direct image sensor captures all primary RGB colors at each and every pixel location. As the photo detectors are arranged in three layers, full and complete color is captured giving the images a three-dimensional feel.
  • The SD15 incorporates the "TRUE (Three-layer Responsive Ultimate Engine) II" image processing engine which improves the processing speed and overall image quality. The unique image-processing algorithm provides high resolution power and reproduces high definition images with richly graduated tones.
  • The SD15 captures light effectively and ensures noiseless image processing. The image sensor provides high definition with rich, gradated tones.
  • The durable focal plane shutter mechanism has a life cycle of over 100,000 exposures and dramatically reduces the amount of dust and dirt from the shutter mechanism.
  • The two motor systems are driven by the mirror-drive and shutter charge which lowers the vibration of the mirror movement, preventing camera shake. The mirror lock-up mechanism raises the mirror, preventing further vibration when the shutter is released.

The SD15 Digital SLR camera is the latest model in Sigma's SD series. Powered by the 14-megapixel Foveon X3 direct image sensor, it can capture all primary RGB colors at each and every pixel location arranged in three layers. The new SD15 incorporates the "TRUE II" image processing engine, which processes the large amount of data from the 14 megapixel direct image sensor.It also provides high resolution power and reproduces high definition images with impressive three-dimensional detail, rich in gradation. The camera adopts the SD card and incorporates a highly visible 3.0 inch LCD monitor, 77-Segment AE sensor and Analog Front End (AFE). It provides high image quality and user friendly design. In addition, the durable shutter mechanism, which has a life of over 100,000 actuations, is ideal for the demands of digital photography. The SD15 has been developed with the principle of producing superior image quality from the direct image sensor, as well as improved processing speed, operation and performance.

Opal in a Pearl - Two Gems in One

!±8± Opal in a Pearl - Two Gems in One

There is always the possibility of combining an opal and another gemstone such as a diamond or ruby. But when this happens it is really making a piece of opal jewelry and adding a diamond accent or a ruby accent. It is a combination but a combination of two gemstones and there is nothing so special about that. But this... this is something very different!

Opals can be millions of years old in their formation and pearls can be a year or two. So is it possible to combine the two in opal jewelry? But this time I mean to make them into one gemstone! Yes, it is and it certainly is most exciting.

In Shark Bay, Western Australia, the two gems are meeting in harmony. Shark Bay is an area where cultured pearls are harvested and that is a considerably sophisticated industry dealing with nature, a fragile environment and at the end of the day a fickle market.

Then, way out in the middle of nowhere in Lightning Ridge, NSW opals are found twenty metres or more underground.

The cut and polished opals are taken to Shark Bay and implanted into a live pearl shell. The oyster is put back into the sea and left there for over a year, perhaps a year and a half. By this time the mother of pearl has covered and embedded the polished black opal and it is ready to harvest.

Over this time the process involves careful observation and tender loving care of the pearl shell.

When the time for harvesting is ready it is taken out of the water and a skilful jeweler prepares the stone and its pearly surrounds to be made into a gorgeous piece of jewellery combining pearl and opal. The result is one of a kind.

The opal pearl combination is wonderfully suited to making pendants. Sometimes the original opal is set in gold before it is places in the pearl shell.

There were many experiments and the original opal in a pearl took three years to harvest and now the public is lucky enough to be able to buy these exciting items of opal jewelry, or is it pearl jewelry?
