Tips and bugs in EMplified

Status: October 2021

The live view images jumps

This only seems to happen when the Drift correction in the Live View is activated. Deactivating the feature should resolve the behavior.

Live View and Drift correction.

The acquired image becomes white

This is a bug in the current EMplified version. It can happen that the images in the Viewport become completely white or black. This has to do with the contrast/brightness setting of the Histogram. In the "Standard new" layout, you can find the global Histogram on the left hand side. The Histogram is active on different windows depending on the operation:

• When the Live View is running, it is active on the "Live View" window or the "Power Spectrum", depending on which window is selected.
• When the Live View is NOT running, it is active on the "Viewport".

When the bug happens and you want to see your acquired image, stop the Live View and click on Reset C/B in the Histogram control panel. Now, the image in the Viewport should look normal. When the Live View is restarted, the image might turn white or black again. As long as you save in 16bit format, the saved images are fine. If you save in 8bit format, there might be an issue with the saved files (they are white or black as well).

So, the strong suggestion is: Save all images in 16bit format!
