The Fuji exploits its Super CCD EXR sensor, with 6MP of bright-light and 6MP of low-light sensors. The camera takes one picture, then combines the best of the highlight and shadow detail in a reduced 6MP file. Set EXR on the mode dial, then DRange Priority in a menu. You can also select the expansion level- for the photo here, we used the highest: 800 percent. Both usurp ISO control. The Fuji sets ISO 200; the Ricoh adjusts sensitivity according to scene brightness.
