Turning off Mac camera's mirror effect

It is annoying that Command-F use to flip the image in Photobooth and, I think, iChat. There must be thousands of people using Facetime from home who would use this feature. Maybe if we all send feedback to Apple (ha ha)
Update…
Despite my reticence I have submitted this feedback to Apple:
Many thousands of people around to world are showing printed documents to others via Facetime (e.g. for giving school lessons from home). The mirror image that we see makes pointing out features on the document, or reading from it, very difficult.
Can you please urgently introduce the “flip image” option that was available in early versions of Photobooth (and, I think, iChat). With Photobooth pressing Command-F flipped the image.

P.S. There is no feedback selection for Facetime
