Why are the black parts of my photos flashing?

Question

Recently I have borrowed my friend's SLR.

I don't know what settings I have changed.

When reviewing a photo, the black parts of the photo are highlighted (flashing) black/white every second.

The manufacturer of the camera is Olympus.

What is going on? How do I fix it?

Answer

You're in the mode of the camera where it shows you the over (or possibly under) exposed parts of your images. Its a useful mode, but if you'd like to exit, click the up or down arrow while you see that image to cycle through the viewing modes.
