To access the Details tab select an image (if the image is in a panel you'll need to double-click on the panel to select the image, making sure the you want to apply the effect is selected):
Now we're ready to apply a filter. Click on the filters popup menu to see the list of available filters:
Try out some of the other filters in the menu to see what effect they have - you'll find there is a wide variety. And we've also provided some Styles for you to try out.
The Invert checkbox inverts the colors in the image (after any filter has been applied) for a photo negative effect.
The Colorize checkbox applies the color shown in the color well to the image - you can get sepia like effects with this - or any other color tone you might like. Again the colorize is applied after any selected filter (and after invert if that is selected).
