The Video Controls palette is where you set camera controls. The exact controls in the palette will depend on the camera but the most important parameters are exposure, binning, gain and auto contrast, although Openlab does not support auto contrast for all cameras. The layers palette is where icons of your images appear as you capture them. When you first launch Openlab there are only two icons in the palette, a blank white Original Image icon representing the empty document window and the Video Preview icon. If you click the Video Preview icon then the document window will display a live image of what the camera sees. Clicking the icon does the same thing as clicking the live preview tool in the document window tool bar. When you click the camera icon in the Document Window tool bar a 'captured layer' will be added to the icon list in the Layers palette.

Openlab Video Controls and Layers palettes

Colourising images and creating colour merges

Clicking on the little arrow on the right of a layer in the Layers palette opens a drop-down list where you can pick a colour from red, green and blue to apply to the layer. Once colours have been applied a new merge layer can be made by selecting the layers you want to merge and dragging them to the New button at the top of the palette.
