 Live preview

Helicon Filter's live preview can be used in either simple mode (commercial and freeware versions) or expert mode (commercial versions only).Simple mode allows the user to control aspects of the picture with fewer sliders, fewer brushes, no equalizers and no Aberrations filter, while expert mode gives the user more sliders along with equalizer control.Live preview can be used to show the final image after editing, can show a split between the edited version and the original, and can show images as a full-screen preview.
