The Fujifilm FinePix S5 Pro is packed with features to improve image quality as well as make life easier for professional photographers. Two of these features, Extended Dynamic Range and Tethered Capture, deserve more attention than could be given in the magazine review (June 2007).
Extended Dynamic Range
The unique double-photodiode matrix in the Fujifilm S-series digital SLR cameras allows the dynamic range of the capture to be varied, either automatically by the camera, or manually by the photographer. In the FinePix S3 there were three settings plus Auto. The S5 includes six settings plus Auto, with three of them identical to those found in the S3.
The settings are given as percentages, from 100% with the lowest dynamic range to 400% giving the greatest dynamic range. Darin Peeple of Fujifilm explains that these percentages are a way of measuring the total availabile ability of the pixels to record information. At the 100% setting, only the larger S-pixels are used and the dynamic range is 100% of their ability. As the dynamic range is extended by choosing other settings, the smaller R-pixels come into play. In combination with the S-pixels, the R-pixels can extend the dynamic range by as much as a factor of 4, thus the 400% maximum setting.

In this instance, the Auto setting produced the same result as the 400% setting. ©Stan Sholik
