The Openlab interface consists of a main menu, a document window and several free-floating palettes. The adjacent image shows the menu and document window. The document window has a bar on the left with tools that you can use to get a live preview (the screen icon), capture images (the camera icon), digitally zoom on images, colourise them, etc. Initially the document window will be empty but the live preview and captured images will appear in here. There should be a few free-floating palettes. The most important ones are the Video Controls and Layers palettes. If they aren't on the screen they might have been closed or minimised to icons at the bottom of the screen. You can open them again by going to Windows in the main menu and selecting Palettes. All the available palettes will appear in a drop-down list but you only need the ones I've mentioned. |
