Openlab is a camera capture software for Apple Macs. I don't recommend learning to use Openlab if you are a new user because development of the software stopped in 2010. The software still works on Macs running OSX up to and including version 10.6.8 but not newer versions, so if a computer running Openlab is replaced or if the version of OSX is upgraded then Openlab will stop working. In that situation you would then need to learn how to use another capture software. Any data you have in Openlab format can still be opened and converted into other formats using Fiji and other software.

Make sure the camera is switched on before opening Openlab, then click the Openlab icon in the dock.

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 (screen icon) and capture images (camera icon), digitally zoom on images, colourise them, etc. Initially the window will be white but when you get a live preview or start capturing images they will appear here.

There may also be floating 'palettes' the most important of which are the Video Controls and the Layers palettes. The Video Controls palette is where you set camera controls such as exposure, gain, etc. The exact controls in the palette will depend on the camera. The layers palette is where icons of your images appear as you capture them. It also allows you to select images to be colourised, merged or exported.
