Samsung uses a pretty typical display layout for its user interface, although I have to admit I find its occasionally faux-analog aesthetic more appealing than most. From the main display (top) pressing Fn brings you to image settings, autofocus area, flash, color space, tonal correction, and image stabilization settings (middle). The rest of the settings, such as the Picture Wizard image controls (bottom), you pull up via dedicated buttons.
Though its defaults deliver relatively accurate results, Samsung's image controls are as frustrating as those on many entry-level dSLRs; they don't tell you what the inherent settings are for each of the different presets, instead leaving everything zeroed out. And Samsung gives you no indication as to which of the presets will provide the most neutral results.
