Digital Cameras – Dynamic Range of the Panasonic DMC-G3.
An example of one of the latest digital cameras is the Panasonic DMC-G3. Constructed from aluminium, the Panasonic Lumix DMC G3 has also been made some 10% lighter than the G2. Despite its smaller size, this latest Panasonic Lumix camera still manages to keep its electronic viewfinder. The sensor on this latest Panasonic Lumix model is now a 15.8 Mp Live MOS. The sensor offers an ISO range of between 160 and an impressive 6400. It also has a new noise elimination circuit at the sensor level itself. In addition, the dynamic range exhibited sets it apart from the rest of the digital cameras within its group.
The ability of the sensors, found within digital cameras, to capture information over the whole range from darkest areas to lightest is called its dynamic range. Whatever digital cameras are being used, their sensors have difficulty capturing the full range of tones that may be present in a photograph. Tones that are too dark won’t provide enough photons, or light, to register in the sensor’s photo-site “buckets,” to give them their correct term. Sensors, unless you specify a lower threshold or amplify the signal, clip the shadows and in so doing increase noise.
This is why professional photographers prefer digital cameras, such as the DMC-G3, that have larger sensors, such as the full frame dSLR’s This allows greater sensitivity and higher ISO settings, reduced noise, and an expanded dynamic range. This is especially so when one selects the RAW format.
Pansonic is the largest manufacture in Lumix cameras which has been a great tool for many photographers all around the world.
