Upside down or reverse image (sorry for my bad inglish but i speak spanish)

Greetings, I purchased a mac and use the webcam picture is upside down, what do I do?

Which webcam are you using and which application? If you are using the built-in camera and Photo Booth.app, the images will be mirror images by default. If you use the option "Auto Flip New Items" in the Photo Booth "Edit" menu, the photos should have the correct orientation.

For any other camera check the compatibility with MacOS X and see, if you can mount it turned differently.

Using Preview you can flip the photo.

Tools menu -> Flip Vertical

You're welcome 🙂
