This is the Expert Mode interface.

You can see how this window has a different size. This is because I adjusted it to the size of this photograph.

You will notice that now you have five Auto cast removing modes, and tabs that handle Cast, Color, Brightness, Extras, Help, Histo, Info and Prefs. More on these later. The histogram at the bottom right is really only one out of the many, as well in appearance as in data it displays.

You will also notice that Expert Mode offers the option to save presets and to re-use them. This can come in very handy, for example when you have to create a larger version of your file and need to colour-correct it again, or when you have to remove a knwn cast like that of a negative film.

In Expert Mode, the reset button is controlled by the set preferences for it. These include an "own defaults" setting which can be saved and re-opened.
