How can rebreather diving be made safer? That was the question at the core of the numerous presentations and discussions at Rebreather Forum 3 (RF3) held in Orlando, Florida, this May.
The last forum, Rebreather Forum 2.0, which I organized with rebreather builder Tracy Robinette, was held 16 years earlier in 1996, at a time when rebreathers were just being introduced to the sport diving market.
When it comes to cameras, traditionally, gear is divided into compact point-and-shoot or single lens reflexes (SLR). Compact point-and-shoot cameras are simple devices that many people use just for snapshots. In order to keep the price low, the lenses are not as sharp as the ones designed for SLRs. Some compact cameras are compatible with add-on conversion lenses to expand their range.
When it comes to cameras, traditionally, gear is divided into compact point-and-shoot or single lens reflexes (SLR). By definition a SLR camera had a mirror and prism positioned inside the camera, so the photographer could look directly through the lens. This way, they could see the exact framing of the image. When the shutter opens, the mirror quickly moves out of the way, so the film or sensor could be exposed to light. SLRs are advanced cameras with manual exposure control and interchangeable lens systems.
