Step 3: Creating photos with different exposures. Select bracketing.
Select check boxes for desired EV values (1), like -4,-2,0,+2,+4 and hit the Start button(2). For this may do more try for better results. For best result it is indicated to set camera mode to "A".
Step 4: Select all images using context menu or selecting one by one using checkboxes on images thumbnails.
After that using same context menu starting utility for exposure fusion(Actions->Enfuse Images). This option start a utility application named enfuse (http://wiki.panotools.org/Enfuse), same application can be used for focus stacking.
Enfuse options: All checkboxes should be unchecked if you want to speed up the process you can down scale image (2). Most important setting is the Exposure (2) this slider sets the relative weight of the well-exposedness criterion. Increasing this weight relative to the others will make well-exposed pixels contribute more to the final output. For other options see the enfuse wiki.
