Test Exposure Settings window

To take a single test exposure with the chosen settings on each connected camera, you have to open the Single Exposure window in Lunar Eclipse Maestro.

Choose Camera > Single Exposure with Settings…
Select the exposure program mode, the ISO sensitivity, the aperture and shutter speed before taking the exposure on the digital camera.
Depending on the selected exposure program mode, a few settings might be disabled. For example, in Program (P) mode, the aperture and shutter speed settings are disabled.

Note : on Canon cameras with a dial, the exposure program mode can not be modified programmatically. This limitation doesn’t exist with Nikon cameras.
